Peptic ulcer disease

Abstract

Peptic ulcer disease (PUD) is defined as a disruption in the innermost lining of the gastrointestinal tract, due to the secretion of gastric acid or pepsin. The disruption is in the gastric epithelial layer, specifically the muscularis mucosae. PUD normally affects the stomach along with the first and second parts of the duodenum, although it is not limited to these areas. Typically, gastric ulcers induce upper abdominal pain within 30 minutes of eating, whereas duodenal ulcers cause discomfort much later. Endoscopic and histological investigations are the key to early identification and treatment of patients with PUD, with testing for Helicobacter pylori necessary in those patients suspected of having PUD. In this article we will be looking at the aetiology, pathophysiology and management of PUD.
