Peptic ulcerrefers to erosion of the mucosa lining any portion of the G.I. tract.
It is defined as : A circumscribed ulceration of the gastrointestinal
mucosa occurring in areas exposed to acid and pepsin and most often
caused by Helicobacter pylori infection. (Uphold & Graham, 2003)
gastric ulcer : the ulcer that occurs in the stomach lining ,some of
them may be malignant
duodenal ulcer : most often seen in first portion of duodenum
(>95%)

The causes of peptic ulcer disease include the following:
Infection with the bacteria Helicobacter pylori occurs in 80 to 95% of
patients with peptic ulcer disease. H. pylori infection impairs the protective
mechanisms of the G.I. tract against low pH and digestive enzymes and
leads to ulceration of the mucosa.
Stress — Emotional, trauma, surgical.
Injury or death of mucus-producing cells.
Excess acid production in the stomach. The hormone gastrin
stimulates the production of acid in the stomach; therefore, any factors that
increase gastrin production will in turn increase the production of stomach
acid.
Drugs: Chronic use of aspirins and NSAIDs, or Corticosteroids

Manifestations of peptic ulcer disease:
• Episodes of remission and exacerbation
• Pain that for duodenal ulcers is often relieved by eating
or antacids
• G.I. bleeding and possible hemorrhage (20 to 25% of
patients)
• Perforation of ulcers with significant mortality
• Obstruction of G.I. tract
