Millions of people around the world suffer from ulcers. An ulcer is a sore or hole
             in the lining of the stomach or duodenum (the first part of the small intestine).
             People of any age can get an ulcer and women are affected just as often as men.
             With stomach ulcers, H. pylori infection is found in 60 to 80 percent of the cases.
             Again, it is still uncertain how the infection acts to cause the ulcer. It probably
             weakens the protective mucous layer of the stomach. This allows acid to seep in
             and injure the underlying stomach cells. However, there is still a great deal of
             research to be done to unravel this relationship. In times past, physicians were
             taught "no acid, no ulcer." The medical profession felt the single most important
             factor causing duodenal ulcers to form was strong stomach acid. Research has
             now shown that over 90% of all patients who develop duodenal ulcers have H.
             pylori infection in the stomach as well. Medical studies are under way to
             determine the relationship between the two and how an infection in the stomach
             can be related to a duodenal ulcer. Acid is still important; patients without acid
             in the stomach never get duodenal ulcers. However, physicians now accept the
             fact that the infection is directly related to the development of duodenal ulcers. It
             is now rather easy to clear duodenal ulcers with the strong acid-reducing
             medicines available. But, the ulcers will usually recur unless the H. pylori
             infection is also cleared from the stomach.
             Although we use to think that spicy food, acid, and stress were the major
             causes of ulcers, we now know that nine out of ten ulcers are caused by H.
             pylori. Helicobacter Pylori is a specific bacteria that can cause infection of the
             stomach. This infection can contribute to the development of diseases, such as
             dyspepsia (heartburn, bloating and nausea), gastritis (inflammation of the
             stomach), and ulcers in the stomach and duodenum....
