What are the symptoms of helicobacter pylori infection?

Some people notice burning or aching discomfort in the upper abdomen, early fullness, belching or reduced appetite. Symptoms may come and go, and some infected people feel well. The infection can irritate the stomach lining and contribute to gastritis or a peptic ulcer. Persistent symptoms cannot identify the cause by themselves, because reflux, medicines and other digestive conditions can feel similar.

Make an appointment if upper abdominal discomfort, nausea or indigestion keeps returning, affects eating or does not settle. Tell the clinician about medicines, previous ulcers and any family history of stomach disease. Testing may use a breath or stool sample; an upper endoscopy may be considered when symptoms or examination findings call for a closer look. Confirmed infection is treated with a prescribed combination that can include antibiotics and acid-reducing medicine.

Seek urgent help for vomiting blood, black stools, severe or sudden abdominal pain, fainting, persistent vomiting or difficulty swallowing. Arrange prompt review for unexplained weight loss, ongoing loss of appetite, anaemia symptoms or worsening pain. These signs need assessment because an ulcer or another stomach condition may require specific treatment.

Ask which test suits you, whether medicines need adjusting before testing, how treatment will be checked, and which symptoms should trigger an urgent review.
