We know that autoimmune disease - a condition when the body's immune system attacks its own healthy tissue and cells - affects millions of people worldwide. But as New York Times bestselling author Dr Gottfried explains in this eye-opening new book, autoimmune disease may be even more pervasive than we realise - and its cause may surprise you. Conventional medicine falls short when it comes to both diagnosing and treating autoimmune disease. Many people suffer from mysterious symptoms like severe fatigue, brain fog, aches and pains, feelings of tingling and numbness, stubborn weight gain, abdominal pain, digestive problems, hair loss, insomnia, and even anxiety, and don't realize their immune system is at the root of their symptoms. In her precision medicine practice, Dr Gottfried noticed a seemingly unusual pattern: many of her patients who suffer from autoimmune disease and symptoms have a history of trauma. Emerging research shows that up to 80 per cent of patients with autoimmune disease experienced significant emotional distress before getting sick.
