It will be useful to know
             some things about the upper digestive tract to understand how and where
             Helicobacter pylori infection can occur. H. pylori is a fragile bacteria that has
             found an ideal home in the protective mucous layer of the stomach. These
             bacteria have long threads protruding from them that attach to the underlying
             stomach cells. The mucous layer that protects the stomach cells from acid also
             protects H. pylori. These bacteria do not actually invade the stomach cells as
             certain other bacteria can. The infection, however, is very real and it does cause
             the body to react. Infection-fighting white blood cells move into the area, and the
             body even develops H. pylori antibodies in the blood. H. pylori infection
             probably occurs when an individual swallows the bacteria in food, fluid, or
             perhaps from contaminated utensils. The infection is likely one of the most
             common worldwide. The rate of infection increases with age, so it occurs more
             often in older people. It also occurs frequently in young people in the developing
             countries of the world, since the infection tends to be more common where
             sanitation is poor or living quarters are cramped. In many cases it does not
             produce symptoms. In other words, the infection can occur without the person
             knowing it. The infection remains localized to the gastric area, and probably
             persists unless specific treatment is given. Medicines that reduce stomach acid
             may make you feel better, but your ulcer may come back. Since most ulcers are
             caused by this bacterial infection, they can be cured for good with the right
             antibiotics. The main cause for ulcers in eating disorder patients is the irregular
             eating habits. When there is no food in the stomach for long periods of time the
