Summary (generated — provider review required)
Mast cell activation syndrome (MCAS) involves inappropriate mast-cell mediator release producing flushing, urticaria, GI symptoms, and reactivity to foods, temperature, and medications. It frequently co-occurs with dysautonomia and hypermobility ("triad"). High reactivity is a key safety consideration before introducing new agents.
