Mast Cell Activation Syndrome (MCAS) is a condition characterized by excessive mast cell activation, leading to chronic symptoms such as flushing, hives, abdominal pain, and anaphylaxis. In toxicology, understanding MCAS is important because individuals with this syndrome may be more susceptible to the toxic effects of certain substances. Proper diagnosis and management of MCAS are crucial to prevent severe reactions to environmental and dietary triggers.
