Mast cells are a type of white blood cell that helps your immune system fight infections and heal wounds. MCAS is an immune disorder caused by a cellular malfunction where mast cells overreact to a harmless, sometimes unknown, trigger. Triggers can include food, medication, odours, and stress. Many parts of the body can be affected (gastrointestinal tract, urinary tract, the lining of the airway, and the skin). Symptoms can include reflux, diarrhea, vomiting, bladder urgency, swelling, shortness of breath, flushing, itching or unexplained rashes. Symptoms can range from mild to severe to life-threatening anaphylaxis.
