H. pylori: Symptoms, Testing and Treatment

Helicobacter pylori (H. pylori) is a bacterium that can infect the stomach lining. Many people have no symptoms, while infection can contribute to gastritis or peptic ulcer disease and is associated with longer-term gastric risks in selected people.

Symptoms and urgent assessment

Symptoms can include upper-abdominal pain, indigestion, nausea or bloating, but these are not specific to H. pylori. Seek prompt medical care for vomiting blood, black stools, persistent vomiting, difficulty swallowing, unexplained weight loss, anaemia symptoms or severe pain.

Testing

Breath and stool-antigen tests can identify active infection; biopsy may be used during endoscopy for selected indications. Some medicines affect test accuracy. NICE dyspepsia guidance advises a washout period after proton-pump inhibitors before breath or stool testing, under clinician direction.

Treatment and follow-up

Confirmed infection is generally treated with acid suppression and antibiotics selected for the individual and local resistance guidance. Complete the prescribed course and do not self-treat with leftover antibiotics. Retesting may be appropriate in defined situations. Treatment success and symptom resolution are not guaranteed.
