Preface

I am a practicing gastroenterologist and a medical school professor, as well as the author of numerous articles for medical journals and self-help books for the general public, such as How to Stop Heartburn and Natural Stomach Care, in addition to books written specifically for physicians. My different roles give me a broad and current overview of both common and rare diseases and disorders of the digestive system. From these perspectives, I see significant advances as well as some disturbing trends. For example, I have seen overweight and obesity rates escalate dramatically in the United States. The majority (two-thirds) of all Americans are known to be either overweight or obese. As a result, they are at risk for many disorders, such as diabetes mellitus, gallbladder disease, hypertension, and the third-most common form of cancer, colorectal cancer, as well as cancers of the stomach and the liver. I urge and challenge readers with a weight problem to lose weight to decrease their risk for these diseases. Even a loss of 10 pounds can make a dramatic difference.
Another issue affecting public health is the rapidly aging population in the United States, with the first of the baby boomers (born between 1946 and 1964) reaching age 65 in 2011, and many more to follow. Older people are more prone to many digestive disorders ranging from gastroesophageal reflux disease and ulcers to cancers of the digestive system. Many elderly people also suffer from chronic constipation and other daily digestive annoyances. These topics are all thoroughly covered in this second edition.
In addition, my coauthor and I discuss alternative remedies for digestive disorders as well as the broad range of medications used to treat digestive diseases. This new edition covers concerns that have recently come to light, such as the risks of nonsteroidal anti-inflammatory drugs (NSAIDs) along with withdrawal of COX-2 inhibitors. In fact, some organizations, such as the American Geriatrics Society, are so concerned about the effects of NSAIDs that in 2009 they urged their members to prescribe opiates to elderly patients rather than NSAIDs.
The new edition also covers the latest technology used to diagnose and treat digestive diseases and disorders; for example, wireless endoscopy enables physicians using a noninvasive means to visualize regions of the small bowel that are not easily within the reach of standard endoscopy, thus increasing the likelihood of pinpointing the causes of obscure gastrointestinal bleeding and other digestive problems. At the same time, double-balloon enteroscopy enables physicians to evaluate most of the length of the small bowel, regions formerly difficult to explore.
The effects of bacteria have been known for more than a hundred years, but despite this knowledge, many patients worldwide have died of bacterial and parasitic infections that were transmitted through contaminated food and water. This new edition provides recent data on both common and less common bacterial infestations that affect the digestive system, such as cholera, Clostridium, and Cryptosporidium. However, many digestive enigmas remain unresolved. There remains much to learn, and important research continues. For example, many forms of cancer are still rapid killers, such as pancreatic cancer or esophageal cancer, frequently causing no symptoms or signs until the disease is far advanced. Other diseases and disorders, such as Crohn’s disease or irritable bowel syndrome, although they usually do not kill patients, can cause misery for years or even decades. However, because of medical advances, instead of wearing a colostomy bag after the removal of the colon for ulcerative colitis, patients may now choose newer surgeries that enable continent bowel function through the anal canal.
