Summary

Up to 1 in 5 people may have this condition and never know it and the diagnoses they've been handed instead, from PCOS to IBS to chronic fatigue, may all be pointing at the same hidden cause. In this episode, I sit down with Dr. Tania Dempsey, Johns Hopkins-trained internist and one of the leading researchers on Mast Cell Activation Syndrome, who tells me that 100% of her PCOS patients test positive for MCAS, and walks me through why mast cells may be the most overlooked driver of chronic illness in modern medicine. If you've been told your symptoms are idiopathic, or that nothing's wrong even though everything feels wrong, this is the conversation that finally connects the dots.

Right now, in my practice, 100% of patients with PCOS have Massel activation syndrome.

0:05.0

Up to 17 to 20% of the population may have Mass Cell Syndrome and not know it.

0:10.0

It mimics dozens of other conditions, allergies, IBS, anxiety, chronic fatigue, skin issues.

0:16.0

Massile activation syndrome, it's a chronic inflammatory, multi-system condition. Everyone has mass cells.

0:22.8

Mass cells are your front line of your immune system. They're helping us, but they can also damage

0:27.9

us. They're chemical messengers, and when their system is faulty, they can chronically secrete

0:33.4

these without an invasion as if one was occurring. Let's look at the root and understand, you know, that the mass cells are affecting the motility,

0:41.3

they're causing inflammation in the gut, they're making more difficult to tolerate certain foods.

0:45.3

This is such a fascinating, underserved area of medicine, where we start really looking at root causes

0:52.3

that people are diagnosed with. It may be something even deeper. But also I want to give hope
