Which specialist treats Helicobacter pylori infection?

Helicobacter pylori is a stomach infection that may cause abdominal pain, bloating, excessive burping, or indigestion. A GP can review symptoms, arrange a breath or stool test, and prescribe an eradication regimen when appropriate. A gastroenterologist is useful when symptoms continue, an ulcer is suspected, treatment has not cleared the infection, or an upper endoscopy is needed.

Start with a GP appointment and mention previous antibiotics, acid medicines, allergies, and any earlier H. pylori tests. Follow the prescribed course exactly and ask whether medicines need to be paused before testing. A follow-up test may be needed to confirm that the infection has cleared; do not assume that symptoms alone provide the answer.

Get urgent medical help for black stools, vomiting blood, severe or worsening abdominal pain, fainting, or marked weakness. These symptoms can indicate gastrointestinal bleeding or another serious problem. Arrange prompt review for ongoing vomiting, difficulty eating, or unexplained weight loss, even if discomfort is mild.

Which test is suitable for me? When should I repeat testing after treatment? What should I do if side effects make the medicine difficult to take? Do my symptoms or history mean I should see a gastroenterologist or have an upper endoscopy?
