Every year, thousands of patients go undiagnosed or misdiagnosed with Mast Cell Activation Syndrome.

What is MCAS? Mast Cell Activation Syndrome causes mast cells to release chemicals that trigger allergic and inflammatory reactions across multiple organ systems.
Symptoms MCAS can cause hives, flushing, abdominal pain, brain fog, fatigue, and anaphylaxis — often triggered by food, heat, or stress.
Diagnosis MCAS is frequently missed or misdiagnosed for years. Awareness and advocacy are critical to getting patients the care they need.
Triggers Common triggers include certain foods, medications, temperature changes, exercise, stress, and infections — varying widely between patients.
Treatment Treatment focuses on antihistamines, mast cell stabilizers, and trigger avoidance. There is currently no cure for MCAS.
Prevalence MCAS is estimated to affect up to 17% of the general population, yet remains widely underrecognized by medical professionals.
Our Mission Detailing for MCAS raises funds for research and empowers the MCAS community through education, advocacy, and support.

The Reality of
Living with MCAS.

Greater awareness means more research funding, earlier diagnoses, and stronger support systems for families. When more people understand and get involved, quality of life for those with MCAS can improve dramatically.
