Millions of people are discovering they are victims of conditions such as chronic fatigue, fibromyalgia, intestinal permeability (a.k.a. leaky gut syndrome), etc.; although these are all relatively new terms to most of us, they are real and debilitating for those who suffer from them. Invisible Illnesses, 2nd Edition covers all these conditions, as well as multiple chemical sensitivities, chemically induced immune system disorders and prescription drug withdrawal syndrome among others. It introduces natural therapies and lifestyle modifications for overcoming these disorders. They emphasize diet, supplementation, non-toxic therapies, environmental modifications, and therapies that encourage the healing process-reserving drugs and surgery as a last resort. With this book, and the guidance of a naturopath or integrative medical doctor, readers can learn what is needed to achieve optimal health, naturally.
