A peptic ulcer is an erosion (a sore) in the lining of the stomach or duodenum, caused mainly by the bacterium Helicobacter pylori or by the use of anti-inflammatory medication. It usually causes burning or night-time pain in the upper abdomen, which is often relieved by eating (in duodenal ulcers) or worsened by it (in stomach ulcers).
How we approach it
Confirming the location and healing of the ulcer is done with gastroscopy, together with testing for H. pylori and its full eradication where present, and avoiding substances that irritate the stomach. Medication includes agents that reduce acid secretion, aiming for complete healing and preventing recurrence.
