Is H. Pylori Dangerous?

A Heliobacter pylori infection that is severe and not treated can be dangerous, especially if there are serious symptoms present. The infection can even be fatal for some patients, although those who receive treatment generally have a good prognosis, explains MedicineNet.

A Heliobacter pylori infection is caused by bacteria that damage the stomach lining, which leads to the development of ulcers, states WebMD. This can cause peptic ulcers and may be a risk factor for gastric cancer, notes the Cleveland Clinic. People can get infected by eating or drinking contaminated foods or fluids. Although some people infected with this bacteria may not suffer symptoms or develop an ulcer, others do. Once an infection has been diagnosed, antibiotics are a treatment option, relates the Cleveland Clinic.
