Mast cell activation syndrome, or MCAS, is being recognized in more and more people, and for families living with autism the pattern is often familiar before it has a name. When sleep falls apart, anxiety spikes, big emotions arrive out of nowhere, and foods, supplements, seasons, and smells all start to become triggers, most people have no language for what is happening. In this episode, Dr. Debby Hamilton builds that language from the ground up.

Dr. Hamilton explains what mast cells actually do, how MCAS differs from a classic allergy and from histamine intolerance (three terms people use interchangeably but should not), where it comes from, and what actually helps. She walks through the decision tree she uses when a child or an adult reacts to everything, and why she calms mast cells and histamine first, before pushing detox or stacking new protocols. She connects histamine and neuroinflammation to the anxiety and big emotions parents recognize fastest, reframing them as an inflamed nervous system rather than behavior.

We also talk about low-histamine foods and the DAO enzyme, why some supplements are tolerated while others are not, how MCAS can hide behind POTS, Ehlers-Danlos syndrome, and IBS, and one calm first step a family can take this week.

"If you're reacting to everything, you go back and you treat the MCAS first." Dr. Debby Hamilton
