Stomach ulcers can be caused by a few
things:
helicobacter pylori - these bacteria is
thought to be responsible for around 60
per cent of stomach ulcers and at least 90
per cent of duodenal ulcers.
Certain medications - including aspirin,
taken regularly to help prevent heart
attack or stroke, and drugs for arthritis.
Anti-inflammatory medications (nsaids)
are thought to cause around two fifths of
stomach ulcers.
Cancer - stomach cancer can present as an
ulcer, particularly in older people.
A stomach or gastric ulcer is a break in
the tissue lining the stomach. The term
'peptic ulcer' refers to those that occur
in either the stomach or the first part of
the small intestine that leads out of the
stomach, called the duodenum.
Treatment for stomach ulcers includes the
use of antibiotics to kill the infection,
and acid-suppressing drugs.
