319: Mast Cell Activation Syndrome: What is MCAS + Why It's So Devastating w/ Jill Carnahan

The Healthy Skin Show

Have you ever heard of mast cell activation syndrome but thought it was the same thing as histamine intolerance? It’s not… MCAS or mast cell activation disorder is much more serious!

Today’s guest dives into what are mast cells and will show you how mast cell activation syndrome (MCAS) is distinctly different and more complex than histamine intolerance.

Though I have spoken about histamine intolerance before (I do see a lot of clients who struggle with this along with chronic hives and dermatographia), it’s important to know if what you’re dealing with is in fact mast cell activation syndrome (MCAS) because of how it will impact your MCAS treatment plan.

So, today I’m joined by the perfect person to talk about what are mast cells and how to deal with MCAS mast cell issues, Dr. Jill Carnahan! She is Your Functional Medicine Expert® dually board certified in Family Medicine for 10 years and in Integrative Holistic Medicine. She is the founder and Medical Director of Flatiron Functional Medicine. As a survivor of breast cancer, Crohn’s disease, and toxic mold illness, she specializes in searching for the underlying causes of illness through cutting-edge lab testing and personalized medicine protocols.
