ABOUT H. PYLORI
What is H. pylori?
Helicobacter pylori (H. pylori) is a type of bacteria that causes peptic ulcers. H. pylori is so tough that it is one of the few bugs that can actually live in your stomach acid. Unfortunately, H. pylori is not the type of guest that you want to stick around. That’s because H. pylori breaks down and irritates your stomach lining. Eventually, this irritation can lead to a painful peptic ulcer.
While H. pylori bacteria can survive in stomach acid, they can also be killed by eradication treatment. Because you shouldn’t take antibiotics if you don’t need them, your doctor will probably want to make sure your peptic ulcer is caused by H. pylori before treating it.
