MCAS: Symptoms, Diagnosis, Treatment, Histamines, Food Sensitivities & Allergies - Dr Tania Dempsey

Dr. Tania Dempsey discusses the complexities of Mast Cell Activation Syndrome (MCAS) in a comprehensive interview. She explains that MCAS is characterized by dysfunctional mast cells which release mediators like histamine, causing widespread inflammation in the body. Symptoms can affect multiple systems, including neurological, gastrointestinal, and respiratory, among others. Dr. Dempsey highlights that MCAS can be triggered by genetic predisposition and environmental factors such as toxins and infections. She also notes the importance of distinguishing true allergies from non-allergic mast cell reactions. The discussion covers various treatment strategies, including antihistamines and dietary approaches like the carnivore diet, which may benefit some patients. However, Dr. Dempsey emphasizes that MCAS management is highly individualized and may require addressing underlying infections, mold exposure, and other comorbidities. Additionally, she touches on the connection between MCAS and heart health, and the potential impact of psychological factors such as trauma. The conversation underscores the importance of an integrative approach to managing complex chronic illnesses.
