The main issue with H. Pylori is that it causes chronic inflammation of the lining of the stomach. So chronic gastritis is the most common issue. Beyond that, patients who have chronic inflammation may have some compromise of the blood flow to that tissue. And so patients who have chronic gastritis are predisposed to developing ulcerations, cuts of sore in the lining of the stomach. And then beyond that, if you have this inflammation over extended periods of time, this chronic irritant in a very small number of cases may cause the cells in the lining of the stomach to change. And in some very small cases, that change may become cancerous.
