Complementary and alternative medicine and gastrointestinal diseases

Complementary and alternative medicine (CAM) is becoming increasingly utilized as a form of health care, with recent studies suggesting that over 40% of Americans use some form of CAM. This has major financial implications for the health care industry. Traditional physicians frequently are unaware of CAM use by their patients, and there are potential interactions between CAM and traditional forms of medical therapy. Many of the medicinal CAM agents have been used for their postulated anti-inflammatory and/or antifibrotic effects. CAM is especially frequently used in patients with chronic diseases. This review discusses CAM use in three types of chronic gastrointestinal diseases--liver disease, irritable bowel syndrome and dyspepsia, and inflammatory bowel disease.
