Dr. David J. Zieger is an integrative Doctor who has a very full tool box for treating his patients. He does a good job of explaining why so many of us have autoimmune conditions now, compared to the past. He discusses the many conditions for which he utilizes LDN (Low Dose Naltrexone). He states that approximately 70% of his patients have thyroiditis and/or Hashimoto’s which LDN can correct through bolstering and regulating our autoimmune systems.
