Gut Origins of Thyroid Health  Practical Applications and Case studies

Featuring Ryan Monahan, FDN-P

Most thyroid autoimmune conversations start with the thyroid itself.

Yet the immune system learns tolerance in the gut and that education depends on several factors; from adequate dietary fiber, environmental and lifestyle stressors to genetics. Where should clinicians begin to best support the gut-immune-thyroid axis? Have you ever heard of the fiber gap?

Drawing on a decade of clinical practice and thousands of functional lab interpretations, Ryan Monahan FDN-P connects the microbiome, immune tolerance, and thyroid function into a single picture and lays out a terrain-first framework for supporting the gut-immune-thyroid axis.

Participants will learn:

-How immune tolerance is established in the gut, and the role of dietary fiber and butyrate in supporting regulatory T cell function

-The role of secretory IgA in immune exclusion, and why its function is central to maintaining tolerance at the mucosal barrier

-The relationship between intestinal barrier integrity and the development of autoimmunity

-To identify microbial and inflammatory factors that influence peripheral thyroid hormone metabolism, including endotoxin-driven shifts in T3 and reverse T3

-How to apply a terrain-first framework, using real case studies, for supporting the gut-immune-thyroid axis in clinical practice
