About Helicobacter pylori

Helicobacter pylori is a stomach bacterium that can cause ulcers and gastritis. It is a medical condition diagnosed and managed by a doctor. The information below is for information only.

What is H. pylori infection?

Helicobacter pylori (H. pylori) is a bacterium that colonizes the stomach or duodenum. It is the most common cause of peptic ulcer disease and chronic gastritis. If left untreated, persistent irritation of the stomach lining can lead to more serious health complications.

Symptoms and causes

How does H. pylori damage the stomach?

The bacteria live in the protective mucus layer of the stomach lining. They produce an enzyme called urease, which neutralizes stomach acid by converting urea into ammonia. This lets the bacteria survive in the harsh acidic environment, where they gradually weaken the stomach tissue.

Common symptoms of infection

Many people are asymptomatic, but when symptoms occur they often mimic gastritis or ulcers:

  • Dull or burning stomach pain (often worse at night or when the stomach is empty)
  • unplanned weight loss and loss of appetite
  • frequent bloating and belching
  • nausea or indigestion (dyspepsia)
  • in severe cases: blood in the stool or bloody vomit

Suspecting an infection? Test yourself at home.

Don't wait for symptoms to worsen. You can run a reliable screening in the privacy of your home with a rapid 10-minute test.

Diagnostics and professional help

If you prefer a clinical diagnosis, your doctor may perform a breath test, stool test, blood test, or a gastroscopy (endoscopy). If H. pylori is confirmed, treatment usually involves a combination of antibiotics and proton-pump inhibitors, decided and supervised by your doctor.
