In this episode of the Healing Powers Podcast, host Laura Michelle Powers speaks with medical doctor and functional medicine expert Dr. Kelly McCann about mast cell activation syndrome (MCAS), histamine intolerance, and the growing number of people experiencing unexplained chronic symptoms. Although mast cell activation was only first described in medical literature in 2007, research suggests that up to one in five people may be affected.

Dr. McCann explains how mast cells—an important part of the immune system—can become overly reactive due to environmental toxins, mold exposure, infections, stress, and trauma. When this happens, it can trigger widespread inflammation throughout the body and lead to symptoms such as allergies, brain fog, digestive issues, insomnia, migraines, anxiety, and fatigue. Laura also shares her own experiences with mold exposure and sensitivities, highlighting how many people struggle to get answers through conventional testing.
