Gastric and/or duodenal ulcer

This is a lesion on the wall that lines the digestive tract, also known as the mucosa.

Predisposing/causing factors include infection by the Helicobacter pylori bacterium, smoking and the use of anti-inflammatory drugs.

It can sometimes be asymptomatic, but the most common symptoms are pain or discomfort in the middle and upper abdomen and heartburn.

The severity may increase with perforation or bleeding.

It is diagnosed by taking a clinical history and carrying out specific tests such as endoscopy and biopsy of the ulcer.

It is treated with medication to eliminate the Helicobacter pylori bacteria (if present) and to reduce stomach acid levels. Drinking limited amounts of coffee and not smoking or drinking alcohol is recommended.
