What are the causes of stomach ulcers?
The direct cause of the ulcer is the destruction of the gastrointestinal mucosa of the stomach by hydrochloric acid, usually in the digestive juices of the stomach. Infection with the bacterium Helicobacter pylori is considered an important role in the cause of gastric and duodenal ulcers to play. Helicobacter pylori can be transmitted to person through contaminated food and water from one person. Antibiotics are the most effective treatment for peptic ulcer Helicobacter pylori.
Lesions of the gastric mucosa and weakened the defenses of the mucosa are also responsible for stomach ulcers. Excess secretion of hydrochloric acid, genetic predisposition, and psychological stress are major factors leading to the formation and worsening of duodenal ulcers.
Another important cause of ulcers is the chronic use of anti-inflammatory drugs like aspirin. Smoking is a major cause of ulcer formation and failure of the ulcer.
