In this episode of The Dr. Hyman Show, the discussion revolves around autoimmune diseases, their causes, and functional medicine approaches to treatment. The speakers discuss the limitations of conventional medicine, which often focuses on suppressing symptoms rather than addressing root causes like toxins, infections, allergens, diet, and stress. They highlight the importance of identifying individual triggers through comprehensive testing and detailed patient history. A case study of a 43-year-old woman with joint pain, brain fog, and fatigue illustrates how functional medicine can uncover underlying issues like thyroid problems, gluten sensitivity, and gut dysbiosis. The speakers also explore various dietary approaches, including anti-inflammatory diets, paleo resets, and the consideration of lectins, emphasizing personalized treatment plans. Dr. Hyman shares a detailed case of a 10-year-old girl with a severe autoimmune disease, dermatomyositis, and how functional medicine principles helped her recover by addressing root causes like mold exposure, mercury toxicity, and gut imbalances.
