H pylori can be challenging. Many patients present with dyspeptic symptoms; physicians often don't find a specific cause and classify them as nonulcer dyspepsia, said Jonathan Leighton, MD, FACG, a gastroenterologist from the Mayo Clinic in Scottsdale, Arizona, and chair of the ACG Educational Affairs Committee. "If in fact some of those patients are infected with H pylori, it's important to know because, obviously, the treatments are very different," he said.
