Obesity has become a major concern among gastroenterologists due to its large influence on gastrointestinal and hepatic diseases: reflux esophagitis, pancreatitis, gallstone disease, liver fibrosis, and neoplastic tumors of the esophagus, pancreas, and colon. Studies of morbid obese subjects undergoing bariatric surgery have revealed that obesity is related with an increased prevalence of endoscopic and histologic gastritis. A recent study of health check-up subjects demonstrated an association of obesity with endoscopic gastritis and gastric ulcers. We recently investigated the underlying mechanisms of the effects of obesity on endoscopic gastritis in subjects undergoing health check-up examination, and demonstrated that adiponectin, a bioactive molecule released from visceral fat, could be a protective factor of endoscopic gastritis. We would like to propose a new category of gastritis, obesity-related gastritis, which could become dominant in the near future. Copyright © 2012 S. Karger AG, Basel.
