Mast Cell Activation Syndrome or MCAS is a debilitating condition where a patient continues to experience allergic reactions, such as hives, swelling, low blood pressure, difficulty breathing, bloating, and severe diarrhea. Dr. Weinstock talks about the symptoms of MCAS and how it can mirror and overlap with Postural Orthostatic Tachycardia Syndrome (POTS) and Ehlers-Danlos syndromes (EDS).In MCAS, the mast cells, a big portion of our immune system, have a gene mutation and are unregulated to set off a cascade of immune and allergic symptoms. Pharmacist Jay Gill talks with Dr. Weinstock to educate us about MCAS, it's symptoms and potential treatments including low-dose naltrexone (LDN) and needed supplements like quercetin, probiotics, etc. Dr. Weinstock practices in St. Louis at Specialists in Gastroenterology.
