Helicobacter Pylori - Abdominal Pain, Indigestion (Bacteria Associated With Pain, Ulcers, Or Cancer) - Clinical Trials

What is Helicobacter Pylori Infection?

Helicobacter pylori (H. pylori) infection occurs when a type of bacteria called Helicobacter pylori (H. pylori) infects your stomach. This usually happens during childhood. A common cause of peptic ulcers, H. pylori infection may be present in more than half the people in the world.

Most people don’t realize they have H. pylori infection, because they never get sick from it. If you develop signs and symptoms of a peptic ulcer, your doctor will probably test you for H. pylori infection. If you have H. pylori infection, it can be treated with antibiotics.

Most people with H. pylori infection will never have any signs or symptoms. It’s not clear why this is, but some people may be born with more resistance to the harmful effects of H. pylori.

When signs or symptoms do occur with H. pylori infection, they may include:

  • An ache or burning pain in your abdomen

  • Abdominal pain that’s worse when your stomach is empty

  • Nausea

  • Loss of appetite

  • Frequent burping

  • Bloating

  • Unintentional weight loss


Make an appointment with your doctor if you notice any persistent signs and symptoms that worry you. Seek immediate medical help if you experience:

  • Severe or persistent abdominal pain

  • Difficulty swallowing

  • Bloody or black tarry stools

  • Bloody or black vomit or vomit that looks like coffee grounds
