Mast Cell Activation Syndrome (MCAS): Symptoms, IBS, POTS & Why It’s Often Missed
Explore how mast cells and histamine sensitivity can drive symptoms across multiple systems
Mast Cell Activation Syndrome (MCAS) is finally gaining attention in conventional medicine—and for many patients with chronic, unexplained symptoms, this shift is long overdue. In this episode, Dr. Polly Watson sits down with Dr. Amy Doherty to break down what MCAS is, why it’s often missed, and how histamine sensitivity can affect nearly every system in the body.
Your nervous system doesn’t differentiate between something that’s life-threatening and something that just feels threatening. – Dr. Amy Doherty
If you struggle with IBS, migraines, POTS, chronic sinus congestion, hives, fatigue, or unexplained inflammation, mast cell activation could be part of the puzzle. Mast cells are foundational immune cells that respond to histamine and environmental triggers. When dysregulated, they can drive widespread symptoms that are frequently dismissed or misdiagnosed.

Dr. Doherty explains the spectrum of MCAS, challenges with lab testing, and practical treatment options—including antihistamines, supplements like quercetin, dietary strategies, trigger avoidance, and nervous system regulation. The conversation also explores the powerful connection between the immune system and the autonomic nervous system, including the role of fight-or-flight activation in chronic illness.

Quotes:
- “We have histamine receptors in our heart. We have them in our brain. It can be related to refractory migraines. We have them in our gut. “- Dr. Polly Watson
- “Your nervous system doesn’t differentiate between something that’s life-threatening and something that just feels threatening.” – Dr. Amy Doherty
- “If you have food and it’s left out for a while, the bacteria will start producing histamine. For someone who’s sensitive, that change from freshly made food to the next day can make a huge impact.” – Dr. Amy Doherty
