Can bacterial infections cause ulcers?

Dr. Jeffrey Crespin
Gastroenterology 28 years experience
Yes: A bacteria called helicobacter pylori is the most common cause of ulcers. The bacteria can be treated by antibiotics. It can be detected on endoscopy or stool or breath tests. Ulcers can also be caused by too much Aspirin or antinflammatory medications.
Dr. Kenneth Cheng
Family Medicine 31 years experience
Yes: Helicobacter pylori is the bacteria that has been implicated as a common cause of ulcers. This bacteria thrives in the highly acidic environment of the stomach where it was previously thought that no bacteria could survive in the acid. In addition to the already mentioned other causes (anti-inflammatory medications and aspirin), alcohol can also "weaken" the stomach lining allowing ulcers to form.
Dr. Cynthia Point
Specializes in Internal Medicine
Yes: H. Pylori bacteria in the stomach are associated with stomach ulcers. If you have a stomach ulcer, you will probably be tested for the bacteria, and if you have it, you can take antibiotics to get rid of it, and reduce your chances of having another ulcer. Not all ulcers are caused by bacteria, though. Some are caused by Aspirin or nsaids, and some other medicines.
Dr. Dean Giannone
Internal Medicine 25 years experience
Yes: There is a bacterium in the stomach, helicobacter pylori, that can cause ulcers. Documentation of this bacterium is important because eradication of such reduces the chance of ulcer recurrence by 95%.
