H. pylori is a spiral-shaped bacterium found in the stomach, which (along with acid secretion) damages stomach and duodenal tissue, causing inflammation and peptic ulcers.
It is believed that H. pylori's shape and characteristics cause the damage that leads to ulcers.
Because of their shape and the way they move, the bacteria can penetrate the stomach's protective mucous lining where they produce the enzyme urease, which generates substances that neutralize the stomach's acids. This weakens the stomach's protective mucus, makes the stomach cells more susceptible to the damaging effects of acid and pepsin, and leads to sores or ulcers in the stomach or duodenum (first part of the small intestine).
The bacteria can also attach to stomach cells, further weakening the stomach's defensive mechanisms and producing local inflammation. For reasons not completely understood, H. pylori can also stimulate the stomach to produce more acid.
Researchers do not yet know what causes certain people to develop H. pylori-related symptoms or ulcers.
The following are the most common symptoms of H. pylori- related for ulcers. However, each individual may experience symptoms differently.
