Speaker:

Hello everybody and welcome to the vP Life podcast brought to you by vitalityPRO.

Speaker:

My name's Rob and I'll be your host on today's episode.

Speaker:

Today we're joined by Dr.

Speaker:

Rui Lopes, a medical doctor and clinical researcher who leverages his expertise

Speaker:

as the medical advisor for Owlstone Medical, a biomedical company that

Speaker:

is aiming to revolutionize the way we test GI disorders including SIBO.

Speaker:

During today's episode we take a deep dive into what Owlstone

Speaker:

are trying to accomplish and how their breathalyzers work.

Speaker:

We then take a step back and explore the world of SIBO, what it is and the various

Speaker:

treatment options that are available.

Speaker:

As usual we get through a lot in today's episode so be sure to

Speaker:

check out the show notes and the transcript should you need them.

Speaker:

And I'd like to ask you a little favor.

Speaker:

Our podcast is slowly gaining traction and we'd love it if you could leave us a

Speaker:

review wherever you listen to podcasts.

Speaker:

This will help us grow, reach more people and allow us to host future guests.

Speaker:

And with that, on with the show.

Speaker:

Hi, Rui.

Speaker:

Thank you for joining us on today's episode of the podcast.

Speaker:

Would you just quickly like to sort of introduce yourself, who

Speaker:

you are and what it is you do?

Speaker:

And then we can just sort of take a deeper dive into OMED health as well.

Speaker:

Yeah, perfect.

Speaker:

Yeah.

Speaker:

Thanks, Rob.

Speaker:

Uh, it's a pleasure to be here.

Speaker:

So, um, The journey where I am today until, um, getting to

Speaker:

Owlstone has been nothing but typical for a doctor usually does.

Speaker:

Somewhere along the way I kind of drifted away from the NHS, but I started

Speaker:

as every doctor starts, completed my studies, um, started working in the

Speaker:

NHS as a physician, and I've been there for the past six, seven years.

Speaker:

And I've always had this very traditional path for my clinical

Speaker:

training and my specialization.

Speaker:

But the interest for research was always there for me.

Speaker:

And around two years ago, motivated a great deal by the fact that

Speaker:

I have two young children, I transitioned onto the industry.

Speaker:

And for that, I've leveraged my research knowledge and my clinical experience

Speaker:

across a variety of therapeutic areas, including gastroenterology, where I'm now.

Speaker:

And this became extremely useful for my role as a medical advisor

Speaker:

at Owlstone um, it's a great role.

Speaker:

It's a great place to work, uh, particularly when you see the cutting

Speaker:

edge research that we produce in breath analysis and, and biomarker analysis.

Speaker:

And this grants us the status of, uh, world leaders in breath research, really.

Speaker:

And OMED is, is just a brand of Owlstone where.

Speaker:

We're pioneering these new breath technologies, such as the OMED

Speaker:

breathalyzer, this portable, precise piece of engineering for the monitoring

Speaker:

of GI disease, such as SIBO and IMO.

Speaker:

Before we sort of dig a bit deeper into OMED, let's just sort of Discuss a

Speaker:

bit more about your sort of foray into gastroenterology, what sort of made you

Speaker:

choose that as a speciality or what sort of do you to that field specifically as

Speaker:

opposed to, I suppose, endocrinology or?

Speaker:

Yeah, so I've done throughout my, my clinical training.

Speaker:

I've, I've had exposure to lots of, um, uh, therapeutic areas.

Speaker:

Gastroenterology was one of them and I've done a lot of research, uh, particularly

Speaker:

in, in biomarker analysis in IBD and IBS.

Speaker:

And that was really the one of the most interesting pieces of

Speaker:

research that I've conducted in the past, in the past few years.

Speaker:

And that was a big selling point for me when, when, um, the

Speaker:

Owlstone role came, uh, to play.

Speaker:

Because it, it landed perfectly with, uh, my experience in biomarker,

Speaker:

um, analysis and discovery.

Speaker:

Uh, because it's, it's the mainstay of, of, of Owlstone.

Speaker:

This, uh, breath biomarker identification and research to try and, and create these

Speaker:

new expedited pathways for non invasive diagnostics of very complex diseases.

Speaker:

Okay, fair enough.

Speaker:

Well, let's dig into the nuts and bolts of it then.

Speaker:

Um, I think a lot of people have heard of SIBO, but maybe not a lot of people

Speaker:

actually know what it really is.

Speaker:

I mean, there are a lot of acronyms out there.

Speaker:

You have SIBO, you have SIFO.

Speaker:

There are various different types of SIBO.

Speaker:

Um, you, there are very different, various different ways of obviously testing it.

Speaker:

But just sort of add from a sort of a 50, 000 foot overview, what

Speaker:

is SIBO and who does it affect and how is it affecting them?

Speaker:

What is this sort of this condition actually doing to people?

Speaker:

Yeah.

Speaker:

So, so if we look at our, our gut, um, and particularly if we break it down into

Speaker:

different parts, small intestine, large intestine, when there's a change in the

Speaker:

composition, the density and the function of the organisms that are in the small,

Speaker:

present in the small intestine, um, This leads to an imbalance of our microbiota.

Speaker:

And the microbiota is this agglomerate of organisms that we have in our GI

Speaker:

tract and other places in our body.

Speaker:

And SIBO, which stands for small intestinal bacterial overgrowth, is a

Speaker:

type of, uh, this imbalance, uh, that we often mention as dysbiosis, which

Speaker:

is characterized by an overabundance of bacteria that are usually in the large

Speaker:

intestine or in the mouth and throat.

Speaker:

And they relocate to a place where they really shouldn't be,

Speaker:

which is the small intestine.

Speaker:

And when these bacteria are present in the colon, they are usually not harmful.

Speaker:

They are part of the normal digestion, so they help breaking

Speaker:

down fiber, for example.

Speaker:

But, however, when, when the stomach and the small intestine usually, have very few

Speaker:

bacteria, and the composition of this, the organisms present here, is very different

Speaker:

from the ones from the large intestine.

Speaker:

And things like, for example, stomach acid and the movement of the food along the

Speaker:

GI tract tends to limit this overgrowth of bacteria in the small intestine.

Speaker:

But any impairment to these protective mechanisms can cause SIBO, and SIBO

Speaker:

can affect a wide range of individuals.

Speaker:

So we believe, according to published literature, it's about one in seven of us,

Speaker:

but it's particularly prevalent in those that have underlying conditions such as

Speaker:

IBS, diabetes, or they've had abdominal surgery in the past, for example.

Speaker:

And the different types of SIBO, as you mentioned, we often categorize

Speaker:

it based on the gas that is produced.

Speaker:

Uh, predominantly by, uh, the organism, uh, in, involved.

Speaker:

So, uh, it could be hydrogen, which is mostly produced in, in SIBO.

Speaker:

Methane, which is mostly produced by, uh, these organisms called Archaea,

Speaker:

in a condition called IMO, which is often branded together with SIBO.

Speaker:

Hydrogen sulfide, for example.

Speaker:

And, and there's different, different gases that are produced

Speaker:

in, in different situations.

Speaker:

And we tend to break it down into different categories of SIBO,

Speaker:

but if you look around in the literature, everything is under the

Speaker:

conglomerate of, of, of SIBO, really.

Speaker:

And, and this, and the development of SIBO can, can occur due to several factors.

Speaker:

Yeah, like I said, an impairment of those protective mechanisms will lead to the

Speaker:

bacteria accumulating in the wrong place.

Speaker:

So things such as impaired gut motility will lead the bacteria to start, start

Speaker:

accumulating in the small intestine.

Speaker:

abnormalities in the structure of the, of the GI tract, disruptions of the

Speaker:

microbiome because of antibiotic use.

Speaker:

There's really a wide range of factors that are crucial for

Speaker:

understanding how SIBO happens and how we can diagnose it and treat it.

Speaker:

Okay.

Speaker:

So it's going to predominantly sort of affect people who are already in a, I

Speaker:

suppose you would say, a diseased state.

Speaker:

But when sort of, I suppose, treating it In a traditional sense, what you

Speaker:

would normally do is you would go to your, uh, your physician and you would

Speaker:

do a traditional breath test there.

Speaker:

Try and sort of analyze which of the forms of SIBO is present.

Speaker:

And I suppose this is where OMED comes in and specifically the

Speaker:

technology you've helped to develop.

Speaker:

How is this different to how you would normally, uh, work with your

Speaker:

physician and treat this condition?

Speaker:

Um, how does the technology work and what is it that You're providing

Speaker:

that it's perhaps different from the status quo, the norm, right?

Speaker:

So, if you consider, for example, um, the case of the UK, we have a system

Speaker:

that is heavily burdened by a lot of complexity in terms of, um, dictated

Speaker:

by, The investment of government budgets and things that, like, for example,

Speaker:

the COVID 19 pandemic that have caused further burdens onto the system.

Speaker:

And you have this amount of people that suffer from GI conditions and GI

Speaker:

symptoms, millions of them, every day.

Speaker:

They struggle to find access to even diagnostic tests for conditions

Speaker:

that could be SIBO, could be IMO, could be something else.

Speaker:

And, and that's where OMED comes, um, into play.

Speaker:

We provide this device that is a point of care portable device, which is precise

Speaker:

and, um, overlaps very nicely in terms of preciseness with, with in clinic

Speaker:

devices that cost millions of pounds.

Speaker:

Um, and this, a, a fraction of the price can allow you to, to measure

Speaker:

accurately, um, gases like hydrogen and methane that we know are involved,

Speaker:

um, in conditions like SIBO and IMO.

Speaker:

Okay.

Speaker:

And, uh, the, the goal of OMED is to provide this platform that

Speaker:

aims to transform how we normally manage gastrointestinal disorders.

Speaker:

And, and the focus is, is being accessible, quick.

Speaker:

Non invasive, allowing the patient and their medical practitioner to

Speaker:

monitor their clinical status almost in real time, which is something that

Speaker:

doesn't really happen at the moment.

Speaker:

And behind this technology is the technology of breath testing that

Speaker:

Owlstone has developed over the years and led us to become the

Speaker:

leaders in breath analysis worldwide.

Speaker:

And for example, if you look at SIBO, at the moment, There's a, a big long

Speaker:

wait for you to access a specialized care for even the diagnostic of, um, uh,

Speaker:

functional, uh, gastrointestinal disorder.

Speaker:

If there's the availability of a device or a test that can provide a diagnosis or

Speaker:

the monitoring component almost in real time, that leads the physician in care to

Speaker:

understand how their interventions have an effect on the levels of the gases, on

Speaker:

the symptoms and on the patient's general

Speaker:

clinical status.

Speaker:

This is a technology that is fundamental for streamlining care for individuals

Speaker:

that suffer from GI symptoms every day.

Speaker:

Okay.

Speaker:

And is this a sort of a direct to consumer device or is this something

Speaker:

that people are having to sort of work with their physicians to sort of acquire?

Speaker:

Is it, um, are you able to just pick one up or, again, is it something

Speaker:

that you would, uh, Maybe go and see your, your PCP and then work with

Speaker:

them utilizing this piece of kit.

Speaker:

Yeah, so at the moment, we're working together with, uh, industry leaders, with,

Speaker:

with gastroenterologists and other, other, um, healthcare practitioners to help them

Speaker:

with the monitoring of their patients.

Speaker:

So.

Speaker:

As things stand now, to acquire the device, uh, to acquire the

Speaker:

OMED breathalyzer, you would have to go through your practitioner.

Speaker:

But the future allows us to, uh, provide this directly to consumer, um, if we want.

Speaker:

This is a, uh, like I mentioned, it's a precise device that allows you to,

Speaker:

comparatively to an in clinic piece of machinery that costs millions of pounds.

Speaker:

measure accurately your levels, allows you to record your symptoms, allows

Speaker:

you to record your lifestyle, your levels of stress, your sleep, uh, your

Speaker:

exercise, um, and, and even your diet.

Speaker:

And, and this almost real time monitoring component is essential for you to

Speaker:

understand how any intervention that you take, any modification that you do.

Speaker:

on yourself and your diet, for example, uh, if it has any impact, uh, in, in

Speaker:

the levels of your gases and ultimately on the underlying cause, which is SIBO.

Speaker:

I'd like to backtrack quickly and just sort of, uh, maybe discuss in

Speaker:

a bit more in, in depth what the difference between your various types

Speaker:

of gases is and how they would present, present differently in terms of

Speaker:

symptoms or what that actually means.

Speaker:

I think we've, uh, talked about a few times You get a methane, you get

Speaker:

hydrogen, and if I'm correct, you also get a hydrogen sulfide form of SIBO.

Speaker:

But when it comes to the nuts and bolts, but maybe how does that

Speaker:

sort of alter either treatment or how does that alter the diagnosis?

Speaker:

So when you look at the gases, the gases are ultimately produced

Speaker:

predominantly by the organism that is underlying the cause of your symptoms.

Speaker:

So if you look at SIBO, SIBO is, like I've mentioned, an overabundance of bacteria.

Speaker:

And there's specific bacteria that tend to produce hydrogen when they

Speaker:

get into contact with substrates.

Speaker:

So anything that comes in your food that doesn't get absorbed goes on

Speaker:

to that, to those bacteria, become essentially their own food and lead

Speaker:

them to produce hydrogen, which in large amounts can lead to symptoms such as

Speaker:

bloating, flatulence, abdominal pain.

Speaker:

And this is for SIBO alone, but if you look at gasses like methane, methane is

Speaker:

traditionally produced by an organism called archaea, which is not a bacteria.

Speaker:

It tends to exist across your whole GI tract.

Speaker:

Um, some people more than others have, uh, lateral preponderance of archaea in their

Speaker:

body, so they become producers of methane.

Speaker:

Uh, so when exposed to certain types of substrate from your food,

Speaker:

essentially, it will lead to the production, the production of, of

Speaker:

methane via the metabolism of hydrogen.

Speaker:

So there's these complex biochemical pathways in the microbiome where

Speaker:

different gases are produced, uh, ones directly from a metabolism of food,

Speaker:

others from metabolism of other gases.

Speaker:

But essentially, what all these gases have in common, and regardless of the organism

Speaker:

that produces them, is that their quantity and the way that they act on the, on the

Speaker:

intestinal wall will drive the symptoms that are, that affect millions of people.

Speaker:

One of the most, uh, known differences, if you, when you talk about hydrogen

Speaker:

and methane, for example, is that people traditionally associate

Speaker:

methane with, uh, IBS, uh, with constipation, which is something

Speaker:

that's been shown in the literature.

Speaker:

Higher levels of methane are associated with a slower GI

Speaker:

tract that leads to constipation.

Speaker:

So it's something that's been observed in IBS, for example.

Speaker:

Um, and higher levels of hydrogen have been, uh, observed.

Speaker:

But for example, in cases of patients that have a faster

Speaker:

GI tract leading to diarrhoea.

Speaker:

But there, there is a large overlap in the symptoms of these conditions and

Speaker:

probably explains why they tend to be agglomerated under the name of SIBO alone.

Speaker:

So, would you then say that, uh, SIBO sort of almost forms the, the base

Speaker:

of a lot of these other GI disorders like, uh, IBD, IBS, Crohn's, Ulcerative

Speaker:

Colitis, is there always going to be an element of SIBO in these individuals

Speaker:

or are they too sort of, can they be very distinct from one another?

Speaker:

I would err on the side of caution is saying always, always will be

Speaker:

SIBO or IMO in those individuals.

Speaker:

We know that a large frequency of, um, of SIBO exists in IBS.

Speaker:

So we know that people that have IBS very frequently have, uh,

Speaker:

SIBO underlying undiagnosed.

Speaker:

And until they're diagnosed and treated, their symptoms are not

Speaker:

appropriately managed, uh, regardless of the intervention that they take.

Speaker:

And we know that SIBO is related to, um, other, uh, medical conditions, other

Speaker:

functional and motility disorders, immune disorders, and, and endocrine disorders.

Speaker:

I wouldn't say that, particularly when you try to associate with other

Speaker:

GI conditions that, um, are very hard to diagnose, like IBS, uh, I wouldn't

Speaker:

say that this is the sole cause, but it is, it is a large contributor, yes.

Speaker:

Okay, then I suppose the next step is to discuss how you are sort of suggesting

Speaker:

physicians go about treating SIBO.

Speaker:

What is, I mean, again, a lot of physicians will sort of utilize

Speaker:

antibiotics as their sort of first port of call, something like Rifampicin.

Speaker:

Um, Rifaximin, I think it's called, but are you sort of advocating

Speaker:

for a more natural approach?

Speaker:

Are you sort of very much looking into drugs as a treatment opportunity

Speaker:

or how are you at OMED going about, uh, yeah, with the supportive side

Speaker:

of it, treating it specifically?

Speaker:

So at OMED and at Owlstone um, as a whole, we tend to base our approach

Speaker:

always backed by, uh, scientific evidence.

Speaker:

And, um, the problem sometimes with the evidence surrounding conditions of, uh,

Speaker:

gut gut brain disorders, for example, Is that, uh, the quality, um, is not

Speaker:

always the best, the quality of the evidence, and, and the studies that are

Speaker:

conducted are relatively underpowered.

Speaker:

However, there is, there is a mainstay of therapy for SIBO and, and IMO,

Speaker:

where we tend to treat, try to treat the underlying cause where applicable.

Speaker:

Antibiotics is, uh, a large contributor to eradicating, uh, the condition.

Speaker:

And then, um, treating nutritional deficiencies, identifying trigger

Speaker:

foods is a big component as well of the treatment of SIBO.

Speaker:

So things like antibiotics, as you mentioned, Rifaximin is, um, the, the

Speaker:

main antibiotic we use to treat SIBO.

Speaker:

Um, and IMO as shown as the best quality of evidence in terms of treatment for

Speaker:

eradicating, eradicating this condition.

Speaker:

But things like, for example, diet interventions.

Speaker:

Uh, obviously, uh, a big, uh, contributor to identifying trigger

Speaker:

foods, identifying tolerances, and try to create personalized, uh, diets long

Speaker:

term that are balanced and allow for, um, um, someone that ha that suffers

Speaker:

from GI symptoms to manage their condition without recurrently having to,

Speaker:

go to antibiotics to get rid of SIBO.

Speaker:

Diet alone has been shown, for example, to starve the bacteria that cause SIBO.

Speaker:

So if we, if you take a targeted approach to identify and restrict the trigger,

Speaker:

the trigger ingredients, then you can successfully manage long term disease.

Speaker:

In terms of when you look at how we, we manage it at Owlstone, we tend to focus

Speaker:

our component on the low FODMAP diet.

Speaker:

We, we see the benefit in the literature of the low FODMAP in the treatment

Speaker:

of IBS and the treatment of SIBO.

Speaker:

Um, and low FODMAP involves Reducing certain, uh, amounts of fermentable,

Speaker:

uh, fermentable carbohydrates.

Speaker:

They tend to be associated with symptoms, uh, such as bloating, and,

Speaker:

and flatulence and abdominal pain.

Speaker:

And in, again, in numerous studies this has been shown to help alleviate

Speaker:

symptoms by, by starving the bacteria and the organisms that produce

Speaker:

the, these, uh, gases in excess.

Speaker:

And in your experience, when somebody's following one of these diets, whether

Speaker:

it be a sort of a low FODMAP diet, or potentially something like a ketogenic

Speaker:

paleo diet, or some form of elimination diet, Are they at some point then

Speaker:

able to reintroduce a lot of the foods that they were previously eating?

Speaker:

Or does this become their quote unquote new normal?

Speaker:

Are they then sort of stuck with this way of eating to sort of remain in a state of,

Speaker:

uh, in a SIBO free state going forwards?

Speaker:

Or is the idea to then sort of allow an in an individual to reintroduce

Speaker:

foods, uh, that they were, that they were otherwise partial to or just form

Speaker:

a, generally a large part of their day?

Speaker:

Diet on a day-to-day basis.

Speaker:

Yeah, that's a great question.

Speaker:

So, uh, one of the problems with these restrictive diets is that when they are

Speaker:

continued for a long time, they tend to lead to nutritional deficiencies because

Speaker:

they are quite restrictive in the way, in the approach that we take for, for

Speaker:

trying to identify these trigger foods.

Speaker:

I think the goal of low FODMAP and other similar diets is The restrictive

Speaker:

part has to be long enough to allow us, uh, to take away, uh, a big group of

Speaker:

foods, but short enough that doesn't cause a tremendous impact on the, on

Speaker:

the clinical status of the patient.

Speaker:

So we don't want to cause, uh, nutritional deficiencies.

Speaker:

But there is a component for reintroduction and the reintroduction

Speaker:

part is very important.

Speaker:

It's not just to identify What gives you symptoms, but also to identify the

Speaker:

tolerance levels of certain certain foods So you might have you might be

Speaker:

okay to consume certain Carbohydrates, for example when you talk about the

Speaker:

low FODMAP diet You might consume a certain carbohydrates with minimal to

Speaker:

no symptoms, but then when you go to increased servings, there might be quite,

Speaker:

uh, quite a lot of symptoms for you.

Speaker:

And you might be okay with that, with constructing your diet around

Speaker:

that, to have limited amounts of those particular trigger foods.

Speaker:

Uh, always present in your diet but at a limit that allows you to,

Speaker:

to go about with your day with no impact in terms of, uh, of symptoms.

Speaker:

But there's, the, the goal is to always test this reintroduction, this tolerance

Speaker:

level occasionally because we know from, for example, allergy studies that

Speaker:

things tend to change along the way across, across the span of several years.

Speaker:

Your tolerance levels to certain foods in things like IBS and and SIBO will vary.

Speaker:

So your diet has to become, has to be modulated around that.

Speaker:

It has become relatively flexible for you to test these, these foods along the way,

Speaker:

trying to make sure that your tolerances increase in the way that your diet remains

Speaker:

balanced and you're not going to a very restrictive pattern that it'll eventually

Speaker:

might get rid of SIBO, but will give you other problems.

Speaker:

Yeah, create nutritional deficiencies along the way.

Speaker:

If, if carbohydrates are essentially what are sort of, well in part, um, driving,

Speaker:

uh, a number of these conditions, then why not just sort of take a sort of a shotgun

Speaker:

approach potentially, and then just use something like a ketogenic diet, which

Speaker:

will sort of remove well all simple sugars and all complex sugars from the equation.

Speaker:

What are your thoughts on sort of a ketogenic approach, and

Speaker:

why, how does it differ from a low, the low FODMAP approach?

Speaker:

So if you look at a low FODMAP, it's not, it's not just carbohydrates

Speaker:

that are involved, and they have been shown to cause symptoms

Speaker:

in people with IBS and SIBO.

Speaker:

I'm not very experienced with, uh, the ketogenic diet as a whole, but I know

Speaker:

that the evidence for things like IBS and SIBO is relatively, there's a relatively

Speaker:

unclear role for, for using it long term.

Speaker:

Now, we know that, for example, with FODMAPs, which are the, uh, low

Speaker:

fermentation, uh, low fermentable oligod and monosaccharides and

Speaker:

polyols uh, we know that these, are things that are poorly absorbed and

Speaker:

are osmotically active, and they go along the intestinal tract, and they

Speaker:

get fermented by these bacteria.

Speaker:

So, if you have a microbiota that is not imbalanced and is dysbiotic,

Speaker:

we know that this will drive those bacteria that predominate and dominate

Speaker:

over others to increasing numbers and increasing places where they shouldn't be.

Speaker:

So we know that a low FODMAP is something that has shown to improve

Speaker:

bloating and gas in patients with IBS, with SIBO, and there's evidence

Speaker:

to support this in the prevention and management of patients long term.

Speaker:

But again, there has to be a lot of caution in terms

Speaker:

of these restrictive diets.

Speaker:

It has to always be done under the auspice of a dietician

Speaker:

or a healthcare practitioner.

Speaker:

to prevent it from, from treating one thing but causing further problems.

Speaker:

Of course, and I think it's always, it should always be noted as you just said

Speaker:

that any sort of intervention should be done under the guidance of a physician.

Speaker:

When sort of treating these conditions, what are your thoughts on compounds

Speaker:

like antimicrobials, like berberine, like colloidal silver to sort of

Speaker:

further support the eradication of some of these underlying issues?

Speaker:

Do you think these sort of more natural, um, remedies have their place,

Speaker:

or would you just sort of prefer to stick to something like an antibiotic?

Speaker:

I think there's a place for, for antimicrobials.

Speaker:

There's definitely evidence for specific, uh, antimicrobials in general.

Speaker:

They're proving their, their antimicrobial activity and,

Speaker:

and other functions in the gut.

Speaker:

Now, I'm, I'm, again, weary in terms of a blanket statement

Speaker:

of using them across, uh, as a replacement, strictly a replacement

Speaker:

for antibiotics, without discussing the benefits and the risks of both.

Speaker:

The antimicrobials, the evidence that exists related to SIBO,

Speaker:

is, uh, of poor quality.

Speaker:

It is there, but it is relatively underpowered studies.

Speaker:

So, there needs to be more research in these natural treatments for

Speaker:

SIBO and IMO and IBS to allow us to confidently say this is something

Speaker:

that we can offer alongside antibiotics or instead of antibiotics.

Speaker:

But again, I'm not completely putting them away.

Speaker:

I think there's a place for them, but it has to be on a case by case situation.

Speaker:

And there are a number of other, uh, therapies and modalities currently

Speaker:

being explored in this space.

Speaker:

I know there's a lot to be said about limbic system retraining

Speaker:

and looking at the vagus nerve and stimulating the vagal nerve.

Speaker:

Is this something you've explored, uh, at all?

Speaker:

Or is this a body of evidence you are in any way familiar with?

Speaker:

And do you think that these approaches that maybe look at,

Speaker:

from a gut brain perspective, it's more a brain gut take on it.

Speaker:

So sort of reversing the order of operations as it were, do you think these

Speaker:

modalities hold any promise or unless you're actually treating the underlying

Speaker:

is pathogenesis, the right word, um, pathology of these other modalities,

Speaker:

perhaps maybe a bit sort of weak in their, um, approach or just underpowered.

Speaker:

Well, there's definitely a, a growing interest around this topic of gut

Speaker:

brain s as being, uh, bidirectional.

Speaker:

Not like you said, not just, uh, brain gut, but gut brain as well.

Speaker:

And what we've seen in terms of research is we know that the mental, the mental

Speaker:

health and anxiety and depression affect the way you perceive your symptoms and,

Speaker:

and affect the existence of symptoms and the frequency in which they occur,

Speaker:

uh, in, in specific populations.

Speaker:

I think they hold promise, uh, for future integration within treatment protocols.

Speaker:

Uh, things like, for example, retraining, uh, limbic system, vagal

Speaker:

nerve stimulation, to address this neural regulation of gut function,

Speaker:

uh, and this interaction between the microbiota and the gut brain axis.

Speaker:

But again, the evidence is still very, very new, very scarce.

Speaker:

There has to be more quality evidence, more, um, more studies done, conducted

Speaker:

to, to see how this, this, this, uh, relationship is bidirectional and can be

Speaker:

modulated both ways with effect on, on, on symptoms and eradication of disease.

Speaker:

But again, I, I don't think this is a, a treatment of its own.

Speaker:

It will always be something.

Speaker:

As, um, used in conjunction with an eradication method.

Speaker:

So it will be something to more manage symptoms long term.

Speaker:

Or, uh, or manage symptoms when eradication is not possible, for example.

Speaker:

Fair enough.

Speaker:

Yeah, I suppose it's going to be always going to be more as an adjunct

Speaker:

therapy and not just a monotherapy.

Speaker:

Exactly.

Speaker:

You mentioned, yeah, you mentioned the future a couple of minutes ago.

Speaker:

Where do you sort of see the future of, of breath testing going?

Speaker:

And, and maybe this is just purely speculation and, Uh, just something

Speaker:

that's of interest to me, but do you sort of see breath testing maybe being

Speaker:

used in the next five to 10 years and sort of a, in a metabolic sense, maybe

Speaker:

as a tool to help navigate and determine certain cancers or at this point, do you

Speaker:

think it's purely going to be kept in the realm of a sort of functional GI care?

Speaker:

Oh no, no.

Speaker:

I think, I think the future of breath testing is incredible.

Speaker:

incredibly promising.

Speaker:

Not just in in GI disease, but just across all areas of medicine.

Speaker:

I think over the next 5, 10 years there's going to be significant advancements.

Speaker:

Not, not just about the accuracy and make them completely translating onto

Speaker:

in clinic methods, but also in the By making it accessible, like we do

Speaker:

with the OMED Breathalyzer device, making it accessible for the masses to

Speaker:

streamline care and reduce waiting lists.

Speaker:

I think that there's, there's, that for instance, there's a great potential to

Speaker:

use breath testing in, in early detection of metabolic diseases, as you said,

Speaker:

um, in identifiying specific biomarkers related to metabolic dysfunction.

Speaker:

Um, there's already ongoing research in the use of breath testing

Speaker:

for, for, for cancer diagnostics.

Speaker:

And this will revolutionize the way we, we screen and diagnose a range of diseases

Speaker:

from, from cancer to liver disease.

Speaker:

The, I think, The world is our oyster in terms of how we can apply these

Speaker:

volatile organic compounds, VOCs and breath, to link with specific

Speaker:

diseases and, and create these non invasive methods to diagnose and treat.

Speaker:

I would be remiss if I didn't ask about probiotics, something that

Speaker:

I probably should have touched on earlier and asked about.

Speaker:

Do you think probiotics have any specific sort of Place in, again, in functional

Speaker:

GI care and, and disease, or are they more or less sort of preventative?

Speaker:

Uh, are they something that you would take prophylactically, do you think?

Speaker:

And sort of, are your strain, are these sort of multi, multi

Speaker:

formula sort of approaches or maybe a single strain approach?

Speaker:

Do you think, do you have any thoughts on probiotics specifically?

Speaker:

Yeah, so I think there's, there's, um, there's a role for both, for

Speaker:

preventive and targeted care.

Speaker:

Okay.

Speaker:

Again, there's data on certain diseases like IBS.

Speaker:

There's limits of data on, on, on probiotics and SIBO.

Speaker:

Um, with, I think, there's recent meta analysis where they show, kind of, both

Speaker:

ways, there's no significant difference with, um, the incidence of SIBO, uh, with

Speaker:

probiotics compared to a control group.

Speaker:

But I think there's a component that we've seen with, uh, with, uh, recent

Speaker:

studies on probiotics in IBS and IBD.

Speaker:

There's a component to use them as targeted therapy, but it will always

Speaker:

be on, on a very bespoke situation with a particular patient and not, not

Speaker:

like a mainstream approach to eradicate or even, or even prevent the disease.

Speaker:

I think there's always There's always a component for prevention in terms of multi

Speaker:

strain, of improving your gut microbiome.

Speaker:

Particularly if you feel better taking it.

Speaker:

And there's no side effects and it doesn't interact with anything that

Speaker:

you take in terms of medication.

Speaker:

Sure, I'm more than happy to advise people to take that approach and trying

Speaker:

to get this balance between health and well being and control of disease.

Speaker:

There's not enough studies out there yet for the targeted approach of probiotics.

Speaker:

For to be able to standardize this treatment formulations to use in patients.

Speaker:

I suppose that sort of naturally leads on to a quick discussion about prebiotics.

Speaker:

Do you think prebiotics again have their place?

Speaker:

Or is that very much sort of a case of adding fuel to the fire?

Speaker:

Especially if there's sort of an underlying pathology again in

Speaker:

the case of something like SIBO.

Speaker:

Are these products helpful?

Speaker:

Are they damaging?

Speaker:

My view of the literature says oftentimes, um, I suppose this also

Speaker:

falls into the FODMAP side of things that if you're adding in a prebiotic

Speaker:

to somebody who's already in a diseased state, that it's probably

Speaker:

just going to make the issue worse.

Speaker:

But do you have a sort of an opinion on that or counter or yeah, what are

Speaker:

your views on prebiotics as a whole?

Speaker:

I think, I think there's a, there's again a benefit for prebiotics in terms

Speaker:

of promoting gut health in general by stimulating the growth of beneficial

Speaker:

bacteria, but again, as I said, It could be adding fuel to the fire, if we promote

Speaker:

it in the diseased state, uh, where we have these specific organisms that feed

Speaker:

on specific foods that are non digested.

Speaker:

And if you're introducing several strains or a particular strain, you might tip

Speaker:

the balance of the scale to another type of dysbiosis, and not necessarily to,

Speaker:

to make it a eubiosis environment where everything works perfectly in your gut.

Speaker:

I would be more wary in using it in the diseased state, in someone

Speaker:

who has active SIBO, versus using it in someone that is looking to

Speaker:

just improve their general health.

Speaker:

Uh, because they, they occasionally have symptoms, they, they feel that

Speaker:

their digestive function is not as good as it could be, and their metabolism

Speaker:

is not as good as it could be.

Speaker:

So I, I think there's, there's um, incorporating it in, in the diet

Speaker:

can be a good and effective way to improve the gut health, but very

Speaker:

wary of using it in diseased states.

Speaker:

I suppose like everything, it is ultimately about just finding balance

Speaker:

and utilizing the right tool and the right individual at the right time.

Speaker:

Exactly right.

Speaker:

I think before we close, I'd just like to, and again, a selfish question.

Speaker:

I'd just like to pick up your brain a little bit about how you, knowing what

Speaker:

you know and uh, and what you've studied and, uh, the clinic and yeah, how you

Speaker:

incorporate these practices in your life.

Speaker:

Do you sort of follow any specific dieting exercise regime?

Speaker:

I hate the word biohacking.

Speaker:

It's sort of almost become cult like.

Speaker:

But do you sort of including any of those sorts of practices in

Speaker:

your life to optimize your life?

Speaker:

Yeah, it's just always interesting to hear it from the horse's mouth, so to speak.

Speaker:

So I would love to say I practice what I preach about, but I'd be lying.

Speaker:

Um, I, I, I tend to maintain, try and maintain a balanced lifestyle.

Speaker:

So in terms of diet, uh, for years I followed the Mediterranean style diet

Speaker:

because I'm Portuguese, but recently that, that, that has become very hard to

Speaker:

achieve, but I tried to, it's all, again, like you said, it's all about balance.

Speaker:

I try to include a bit of everything in my diet.

Speaker:

I try to not restrict myself too much.

Speaker:

'cause fortunately, I, I, I don't suffer from GI problems.

Speaker:

So, uh, but I try to maintain my diet relatively balanced by

Speaker:

including a bit of everything and, uh, not letting it tip to excess in

Speaker:

a particular, in a particular part.

Speaker:

Um, in terms of, uh, in terms of exercise, could do more, I, I, I enjoy hiking

Speaker:

and climbing and, and occasionally, uh, I, I do that and, uh, it helps me to

Speaker:

stay active and, uh, cardiovascular, um, cardiovascular exercise does me to,

Speaker:

to, to feel a bit better about myself.

Speaker:

I've, I've, I've attempted diets in the past, so something like periodic

Speaker:

fasting, intermittent fasting.

Speaker:

Which, which helps, but it's very difficult to maintain, um, long term.

Speaker:

But, but there's, there's a lot of things that, that, that you could do, alongside

Speaker:

of things like, for example, uh, specific diets, uh, specific treatment regimens,

Speaker:

uh, uh, sorry, exercise regimens, and, and things like cold exposure, for example.

Speaker:

But I think it's all about balance.

Speaker:

As long, as long as you can find balance for you, cause, uh, it's not a one size

Speaker:

fits all kind of thing, as long as you find balance for you and what works for

Speaker:

you, and try and maintain that, don't let it tip towards one end of the scale, just

Speaker:

try and, and, Allow a bit of everything.

Speaker:

Don't restrict yourself too much because long term it's very hard

Speaker:

to maintain and will probably, um, have worse consequences.

Speaker:

But yeah, I think, I think I'm managing so far.

Speaker:

But I, um, I'm definitely not, not, uh, practicing what I preach.

Speaker:

So, uh, I'm not not the best example.

Speaker:

No, well, I mean you are otherwise healthy.

Speaker:

So if not, why not?

Speaker:

But yeah, no, I couldn't agree more.

Speaker:

Um, and just to sort of reinforce what you just said, this sort of

Speaker:

concept of biochemical individuality is, uh, is very important.

Speaker:

And I do find it fascinating that a lot of people in the influencer space Who sort of

Speaker:

promote these very extreme diets, whether it be carnivore or vegan or ketogenic.

Speaker:

They all, over time, you watch them, Paul Saladino, the individual who really

Speaker:

pushed the carnivore diet for a long time, being a prime example of this,

Speaker:

they always seem to come back to center, whether it's sort of reintroducing

Speaker:

carbohydrates, reintroducing vegetables.

Speaker:

Uh, practicing less fasting, uh, fasting is a stressor obviously in

Speaker:

a, in a, in a therapeutic sense.

Speaker:

Um, it's amazing, but only in the short term, uh, obviously with long term

Speaker:

use, you're going to potentially create dysfunction in your HPA axis and creates

Speaker:

all sorts of hormonal dysregulation there.

Speaker:

So yeah, no, I couldn't agree more.

Speaker:

It's, it's, it's ultimately about maintaining that sort

Speaker:

of healthy middle ground.

Speaker:

Where's the best place to find you and your company.

Speaker:

Rui?

Speaker:

I know you've mentioned both Owlstone and OMED for the consumer who's looking

Speaker:

to potentially particularly purchase one of the, these breath analyzing, uh,

Speaker:

products, where would you point them to?

Speaker:

Yeah, so if, if you're interested in, in learning more, um, you can find

Speaker:

regular updates and, and our latest research and developing in our websites.

Speaker:

So generally about breath research at Owlstone Medical and, uh, more

Speaker:

specifically about g the GI space, uh, OMED Health, so omedhealth.com.

Speaker:

And owlstonemedical.com for detailed information about what we do and how

Speaker:

we are advancing the field of breath based diagnostics and research.

Speaker:

Um, I intend to, to publish some of those updates as well in latest research

Speaker:

and developments in my LinkedIn.

Speaker:

So if you feel free to contact me there.

Speaker:

Okay, perfect.

Speaker:

And we'll publish links to all of those socials and websites in the show notes

Speaker:

as well as any other studies that we sort of either mentioned or discussed.

Speaker:

or that I would think that the listener would otherwise find interesting in

Speaker:

the, yeah, again, in the show notes.

Speaker:

Thank you so much for your time.

Speaker:

We really appreciate it.

Speaker:

This has been enlightening.

Speaker:

Definitely learned a lot and we'll have to get some points soon.

Speaker:

Yeah, thank you.

Speaker:

It's been great to be here.

Speaker:

Thanks Rob.
