Core Tip
Core tip: This review deals with the active clinical problems related to Helicobacter pylori (H. pylori) infection in obese patients. Even if still controversial, the infection might represent a confounding and limiting factor in bariatric surgery, due to the high incidence of postoperative foregut symptoms and/or lesions in non-eradicated patients. The controversies on preoperative H. pylori screening are highlighted, as well as those related to its clinical management, which is complicated by the low eradication rates in obesity. Finally, a revision of studies on the possible correlation between H. pylori and body mass index and its possible protective role in development of obesity is included.
