A condition where mast cells abnormally activate, causing multi-system symptoms including flushing, hives, and GI issues.
About MCAS
Mast Cell Activation Syndrome (MCAS) is a condition where mast cells abnormally activate and release excessive amounts of chemical mediators, causing multi-system symptoms including flushing, hives, GI distress, brain fog, and anaphylaxis. Compounded medications are often essential for MCAS patients because commercial products frequently contain dyes, fillers, and preservatives that trigger mast cell reactions.
