MCAS, Histamine Intolerance and Chronic Fatigue
Mast cell activation syndrome (MCAS) and histamine intolerance may be part of the complex web of imbalances in Chronic Fatigue Syndrome (CFS/ME) and other chronic illnesses.
MCAS can be associated with pain, cognitive dysfunction, brain fog, sensitivity to light and sound or intolerance to chemicals and smells. Many of these symptoms, and more, go hand in hand with those who experience a chronic illness.
