When H. pylori enter your body, it attacks lining of your stomach which protects you from the stomach acid that the body uses for digestion. These bacteria have adapted themselves to live in harsh and acidic environment of the stomach and they can change stomach environment around them by reducing its acidity so that they can survive. Their spiral shape helps them to easily penetrate the stomach lining and the immune cells of the body can’t reach them and so they can damage the stomach lining. This damage allows the stomach acid to get through the lining which results in ulcers. This can also cause infections and bleeding when food moves through your digestive tract.

People can get H. pylori through water, food or utensils. It is more common in those countries that lack clean water or do not have good sewage systems. The bacteria can transfer through saliva or other fluids of body of the infected person. Most of the people get H. pylori in childhood but adults can also get it.

Doctors are still not sure why some people only get ulcers.

Histamine (H-2) blockers: They block histamine, a substance which triggers production of stomach acid. Examples include ranitidine (Zantac) and cimetidine (Tagamet).
