## Resource

Mast Cell Activation Syndrome can affect nearly every system in the body—but its symptoms are often dismissed, misdiagnosed, or mistaken for anxiety. Michelle Shapiro, RD, joins Drs. May and Tim to explain MCAS, histamine intolerance, and the overlap with long COVID, POTS, and hypermobility. They also discuss why common treatments may backfire in highly sensitive bodies and why healing requires an individualized approach.
