Classification
A peptic ulcer may arise at various locations:
A peptic ulcer , also known as PUD or peptic
ulcer disease[1]
is an
ulcer of an area of the
gastrointestinal tract that is usually acidic and thus
extremely painful. 80% of ulcers are associated with
Helicobacter pylori, a spiral-shaped bacterium that lives
in the acidic environment of the stomach, however only 20% of
those cases go to a doctor. Ulcers can also be caused or worsened
by drugs such as
Aspirin and other
NSAIDs.
Contrary to general belief, more peptic ulcers arise in the
duodenum (first part of the
small intestine, just after the stomach) than in the
stomach. About 4% of stomach ulcers are caused by a
malignant tumor, so multiple biopsies are needed to make sure.
Duodenal ulcers are generally
benign.
