What Is The Cause And Treatment For Recurrent Stomach Ulcers?

Yes. I have an extensive history of stomach problems, including a duodenal ulcer, strictures, ulcers, pain, cramps, etc. A recent episode of hypermesis led to hospitalization, where an endoscopy revealed another stricture, as well as an infection referred to as e. pylori . My internet searches do not find e. pylori! Since I cannot get the scripts for the antibiotics the doctor prescribed, how long do I have before the infection turns into cancer?
