How common is persistent indigestion in Helicobacter pylori infection?

Helicobacter pylori is a bacterium that can live in the stomach. When it causes symptoms, people may notice upper abdominal discomfort, burning, bloating, nausea, early fullness or indigestion that keeps returning. Similar symptoms can come from reflux, medicines, irritation of the stomach lining or other digestive conditions, and some people with the infection have no symptoms.

Testing is needed to establish whether Helicobacter pylori is present. A clinician chooses the test based on your symptoms, medicines and whether there are warning signs that need a different assessment.

Arrange a medical review for indigestion that lasts, recurs or affects eating and sleep. Tell the clinician about pain location, appetite, nausea, anti-inflammatory medicines and acid-reducing treatment. Ask whether a breath test, stool test or another assessment is suitable, and check whether any medicines need to be paused before testing.

If treatment for Helicobacter pylori is prescribed, take it as directed and ask how follow-up testing will confirm that the infection has cleared.

Get prompt medical care for vomiting blood, black stools, severe or worsening abdominal pain, repeated vomiting, trouble swallowing, unexplained weight loss, chest pain or fainting. These features need evaluation and should not be managed with self-treatment alone.

Ask which test is appropriate, whether current medicines could affect the result, what treatment involves if the test is positive, and when you should contact the clinic about persistent symptoms or side effects.
