Does upper endoscopy treat Helicobacter pylori infection?

During an upper endoscopy, a flexible camera is guided through the mouth to view the oesophagus, stomach, and first part of the small intestine. A clinician may take small stomach tissue samples when looking for H. pylori or investigating symptoms such as upper abdominal discomfort, nausea, or bleeding.

The procedure and the treatment have different purposes. If infection is confirmed or strongly suspected, eradication usually involves a prescribed combination of medicines, commonly including antibiotics and an acid-reducing medicine. The exact plan depends on medical history, previous medicines, allergies, and local prescribing guidance.

Ask why endoscopy is being recommended and whether a breath or stool test could answer the diagnostic question in your situation. If samples show H. pylori, take the full prescribed course exactly as directed and tell the prescriber about allergies or previous antibiotic problems.

Follow-up testing may be used after treatment to check whether the infection has cleared. Ask when to pause acid-reducing medicines before that test, because some medicines can affect the result. Do not reuse leftover antibiotics or share them with another person.

Get urgent care for vomiting blood, black stools, severe or rapidly worsening abdominal pain, fainting, confusion, or inability to keep fluids down. After endoscopy, seek prompt advice for increasing chest or abdominal pain, fever, breathing difficulty, or persistent vomiting.

Ask whether you need endoscopy or a non-invasive test, how samples will be checked, which treatment is planned if H. pylori is found, and how eradication will be confirmed.
