Overview

Stomach ulcers, also called gastric ulcers and grouped with duodenal ulcers under the term peptic ulcers, are open sores that form in the lining of the stomach or upper small intestine when the protective mucosal barrier is breached and digestive acids damage the underlying tissue. The two most common causes are infection with the bacterium Helicobacter pylori and the long-term or heavy use of nonsteroidal anti-inflammatory drugs such as aspirin and ibuprofen, both of which can weaken the mucosal defenses. Symptoms often include burning upper-abdominal pain, bloating, nausea, and, in more serious cases, bleeding that may manifest as dark stools or vomiting of blood. Untreated ulcers can lead to complications such as hemorrhage, perforation, and obstruction. Diagnosis may involve endoscopy and testing for H. pylori, and treatment typically combines acid-suppressing medications, such as proton pump inhibitors, with antibiotics when infection is present, along with avoidance of contributing factors. Within the study of Digestive Disorders And Diagnosis, stomach ulcers illustrate the interplay between gastric acid, mucosal protection, infection, and medication effects. Research in this journal has addressed related topics including the market and quality of anti-ulcer drugs. This page gathers peer-reviewed, open-access research relevant to stomach ulcers and digestive disorders.
