Mast cell activation syndrome (MCAS) is an emerging condition that sees mast cells, a major player in the human immune system, chronically release mediators (chemicals) which causes a myriad of symptoms. MCAS goes hand-in-hand with other complex chronic illness including mold-related illness, electromagnetic hypersensitivity syndrome (EHS)/electromagnetic (EMF) sensitivity, myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), fibromyalgia, postural orthostatic tachycardia syndrome (POTS) and more.

Dr Olivia Lesslar, MBBS will explain the role of mast cells in the immune system, what happens when they go awry, and the mechanism of MCAS. She also explains how MCAS is diagnosed and what management and treatment strategies are possible. Dr Sandeep Gupta, MBBS is a guest instructor for module 6, that details the environmental and toxic drivers of MCAS including mold, heavy metals and man-made chemicals.
