This book was written to help you avoid heart disease and PBS. If it's already too late to avoid these problems, this book can help you recover. The first few chapters explain how common germs cause heart disease and raise cortisol levels. Beginning with Chapter 6, the emphasis shifts toward cortisol-related illnesses: high blood pressure, obesity, and type 2 diabetes. Chronic subtle hypercortisolism is the technical term for potbelly syndrome, and Dr. Marin explains how to diagnose this disorder in Chapter 16.
