In today's episode, we interview Dr. Leonhard Weinstock on the topic of mast cell activation disorders and the gut, which are becoming epidemic in the population. Mast Cell Activation Syndrome (MCAS) is a complex and often misunderstood disorder that involves the abnormal release of mast cells in the body. These cells are an essential part of our immune system, but when they become overactive, they can trigger a range of symptoms and health issues. Key Points ✅ How did you get into the study of medicine and gastroenterology and what led you to become an expert in MCAS? ✅ Describe in detail what symptoms are related to MCAS and how symptoms might manifest in the gut and other areas of the body? ✅ What do you think we've seen a rise in MCAS diagnoses? ✅ Let's talk more about TRIAD (EDS, MCAS, POTS) and how this can manifest together? ✅ What are some ways we can treat MCAS? ✅ What is the connection with MCAS and psychiatric symptoms/mental illness?   Dr. Leonard B.
