How Does Someone Develop MCAS? - Dr. Tania Dempsey

Dr. Tania Dempsey discusses the development of Mast Cell Activation Syndrome (MCAS) as a progressive condition often rooted in early life. According to Dempsey, many patients with MCAS have dysfunctional mast cells from a young age, potentially due to environmental exposures or toxins. Over time, these exposures—such as chemicals found in pesticides, petrochemicals, or even medical implants—can lead to increased dysfunction of mast cells. This process can eventually lead to chemical intolerance and exacerbate the symptoms of MCAS, making management increasingly difficult. The discussion highlights the role of environmental factors in triggering and aggravating MCAS and emphasizes the need for understanding these triggers in managing the condition.
