Stomach ulcer

A stomach or gastric ulcer (also called a peptic ulcer)  is a break in the tissue lining the stomach. This is a small erosion (hole) in the gastrointestinal tract.It’s happen in the duodenal, occurs in the first 12 inches of small intestine beyond the stomach.

A variety of causes
A stomach ulcer can be caused by a variety of factors, including:

• 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. Today, research shows that most ulcers (80 percent of gastric ulcers and 90 percent of duodenal ulcers) develop as a result of infection with a bacterium called Helicobacter pylori (H. pylori).
• 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.
• Alcohol - Although no proven link has been found between alcohol consumption and peptic ulcers, ulcers are more common in people who have cirrhosis of the liver, a disease often linked to heavy alcohol consumption

A severe, untreated ulcer can sometimes burn through the wall of the stomach, allowing digestive juices and food to leech into the abdominal cavity. This medical emergency is known as a perforated ulcer. Treatment generally requires immediate surgery. Treatment options include antibiotics and acid-suppressing medications.

What does a stomach ulcer affect?

The main thing that a stomach ulcer affects is the nerves surrounding it. The nerves become agitated and cause a great amount of pain. However, stomach ulcers can cause hemorrhages from the erosion of a major blood vessel; a tear in the wall of the stomach or intestine, with resultant peritonitis; or obstruction of the gastrointestinal tract because of spasm or swelling in the area of the ulcer.
