Hello! Is there anybody who can tell me how H. Pyloria causes peptic ulcer? My father has it, and I would really like to know this. Thank you!

Hi there! As you probably already know, H.PYloria is a spiral shaped bacterium that lives in the stomach and duodenum. It has a unique way of adapting in the harsh environment of the stomach. H. pylori weaken the protective mucous coating of the stomach and duodenum, which allows acid to get through to the sensitive lining beneath. Both the acid and the bacteria irritate the lining and cause a sore, or ulcer. H. pylori survives in stomach acid because it makes enzymes that neutralize the acid. This mechanism allows H. pylori to make its way to the protective mucous lining.
