Peptic Ulcer

A break in the lining of the stomach. Normally the lining of the stomach and small intestines is protected against the irritating acids produced in the stomach. If this lining stops working correctly and breaks down, it results in inflammation or an ulcer.

Ulcers usually occur in the first layer of the inner lining—it is not a hole.

Symptoms
 Abdominal pain, nausea/vomiting, smoking, heavy drinking, fatigue, pallor, epigastric tenderness
