Peptic Ulcer

CLINICAL NUTRITION 3(2+1)
Lesson 11 : Diseases of the stomach and duodenum

Introduction

A peptic ulcer is a hole in the lining of the stomach, duodenum, or esophagus. An ulcer is a sore or erosion that forms when the lining of the digestive system is corroded by the acidic digestive juices. It is estimated that between 5% and 10% of adults globally are affected by peptic ulcers at least once in their lifetime.

When a peptic ulcer affects the stomach it is called a gastric ulcer, one in the duodenum is called a duodenal ulcer, while an esophageal ulcer is an ulcer in the esophagus. When the lining of these organs is corroded by acidic digestive juices secreted by stomach cells peptic ulcers can form.

The first symptom of peptic ulcer is usually stomach pain - caused by the ulcer and intensified by stomach acid coming in contact with it. However, it is not uncommon for people to have a peptic ulcer and no symptoms at all. Even though stomachache is the first symptom, most stomachaches are not serious and do not mean the individual is ill.
