If you’ve been dealing with reflux, bloating, constipation, or even anxiety and can’t figure out why, histamines might be part of the picture. In this episode, I’m joined by Michelle Shapiro, RD, to break down the connection between histamine intolerance, MCAS, and gut symptoms and why so many people feel worse with standard gut protocols.

Michelle and I discuss:

What histamine intolerance really is and how it overlaps with MCAS
The wide range of symptoms histamine issues can cause (and why they’re often missed)
How the gut, DAO enzyme, and microbiome influence histamine balance
Why nervous system support is just as important as gut support
Practical steps you can take if you suspect histamine intolerance

Michelle also shares her personal journey with histamines, mold exposure, and POTS and how slowing down and supporting safety in the body can be a turning point for healing.
