The focus of the practice is on enteropathies, with symptoms of abdominal pain/discomfort, gas (bloating, distention, flatulence, and noisy bowel sounds), and bowel dysfunction (diarrhea, constipation, or both). The symptoms of IBS (irritable bowel syndrome) and SIBO (small intestinal bacterial overgrowth) are the same, and they are interrelated. SIBO is a condition that has many causes, the most common of which is IBS-D (diarrhea) or IBS-M (mixed). Most patients with IBS-D/M have associated SIBO. If IBS-C (constipation) is present, most have an associated Methanobrevibacter smithii "bloom," a predominantly colon overgrowth of the microbe that manufactures methane, which causes or contributes to constipation. This is a different condition than is SIBO.




I’m board-certified in Internal Medicine and Gastroenterology, with a Sub-Specialty in IBS, SIBO, and the Microbiome. I have over 40 years of experience: caring for patients with IBS, teaching medical students and residents, and lecturing other doctors. I have written IBS: A Gastroenterologist Answers Your Questions because I am passionate about helping patients learn about IBS and how to get well. It is extremely gratifying to have made a difference in thousands of my patients’ lives, and I’d like to help you, too. And so, I’m going to answer your IBS questions in this book. You’ll become an “IBS expert” so you can work effectively with your doctor and other care givers. Join me on a short journey through the pages of this book. It will change your life.

I am in the process of writing a new book: IBS, SIBO, and the Gut Microbiome: Help From a Caring and Expert Gastroenterologist.

Written by an M.D. gastroenterologist and IBS expert, this comprehensively illustrated ebook integrates the latest medical science and understanding of IBS with a whole being and mind/brain - body/gut) approach to diagnosis and treatment.

IBS is a functional disease. The term, "functional" means disturbance or dysfunction in how the body works. The ebook explains how and why IBS so commonly occurs with other functional GI conditions (such as heartburn unresponsive to strong acid reducers, upper abdominal pain not caused by an ulcer, and abdominal bloating with or without actual enlargement, called, "distention") and with functional symptom syndromes (such as fibromyalgia, fatigue, chronic headache, back pain, and interstitial cystitis.
