Book excerpt: According to recent statistics from the Centers for Disease Control and Prevention (CDC), 34.9 percent or 78.6 million U.S. adults are obese. In addition, about 17 percent, or 12.7 million U.S. children, between the ages of 2 to 19, are obese. In addition, obesity-related conditions, such as heart disease, stroke, type 2 diabetes, and even some cancers are increasing. These alarming statistics coupled with the exponential growth of medical costs to treat obesity, have created an urgency to find effective treatment options. Weight-loss (bariatric) surgery has become a preferred, and cost-effective, treatment option. This book is an overview of weight loss surgery. Written by Scott A. Cunneen, MD, FACS, the Director of Bariatric Surgery at Cedars-Sinai Medical Center in Los Angles and leading expert, the book is a concise resource for people with diabetes who are considering weight-loss surgery. Following the American Diabetes Association's 21 Things Series premise and structure, Dr. Cunneen covers all the important questions patients have when facing weight-loss surgery, such as, the types of bariatric surgery, how to prepare for the procedure, what to expect after surgery, establishing new habits and food routines, and managing the patients expectations.
