In mast cell activation syndromes, people have symptoms of mast cells being activated even though they have a normal number of mast cells. Their mast cells are being triggered inappropriately. Chemical mediators released by those mast cells can cause symptoms such as flushing, itching, hives, headache, gastrointestinal symptoms and low blood pressure.
