Gastric(stomach) ulcers are crater like lesions in the lining of the stomach. They can also be located in the duodenum(small intestine). The lesions cause pain and may lead to perforation and bleeding. Most gastric ulcers are caused by the bacteria Helicobacter pylori.
Treatment of gastric ulcers is twofold. First, proper antibiotic therapy aimed at eradicating the H. pylori is initiated. Secondly, medications that decrease gastric acid are started. Increased amounts of gastric acid aggravate the ulcer and make it worse.
People with diagnosed gastric ulcers can also make lifestyle changes to decrease the amount of acid in their stomachs like quitting smoking, decreasing stress.
