Peptic Ulcers Support Group

A peptic ulcer is an ulcer of one of those areas of the gastrointestinal tract that are usually acidic. Most ulcers are now known to be associated with Helicobacter pylori, a spiral-shaped bacterium that lives in the acidic environment of the stomach. About 4 % of gastric ulcers are caused by a malignant tumor, which is one reason to be vigilant in their detection.
