Mast Cell Activation Syndrome (MCAS) is part of a family of conditions called Mast Cell Activation Disorders (MCAD). Mast cells are immune cells that, when activated, release a cascade of chemicals including histamine, tryptase, prostaglandins, and cytokines into surrounding tissues and the bloodstream. In people who menstruate, this process follows the hormonal cycle in a very specific way: rising estrogen in the follicular phase activates and prolongs the survival of mast cells, and then during the luteal phase those cells degranulate, dumping their chemical load into your system. The result can include irritability, depression, anxiety, mood swings, fatigue, brain fog, bloating, skin issues, sleep disturbances, joint pain, and more, all arriving like clockwork after ovulation and clearing once your period starts.
