Heliobacter Pylori


Helicobacter pylori (H. pylori) is a type of bacteria that can cause an infection in your stomach. Caregivers do not understand exactly how you get an H. pylori infection. An H. pylori infection usually occurs in childhood and may persist for many years. H. pylori may weaken the protective layer of the stomach and damage the underlying stomach cells. This can lead to the formation of stomach ulcers.

You have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.


  • Medicines used to treat H. pylori may cause nausea, vomiting, mouth irritation, or skin rashes.
  • If untreated, an H. pylori infection may lead to inflammation, bleeding, or ulcers that may perforate (cause a hole through the tissue). This may cause an abdominal infection and peritonitis (swelling of the abdominal wall). If this happens, surgery may be needed to treat your ulcer and other problems. An H. pylori infection may also increase your risk for stomach cancer or lymphoma.

An IV (intravenous) is a small tube placed in your vein that is used to give you medicine or liquids.


  • Antibiotics: This medicine is given to help treat or prevent an infection caused by bacteria.
  • Antacids: You may need antacids to decrease stomach acid.
  • Antiulcer medicine: This medicine helps decrease the amount of acid that is normally made by the stomach.
  • Antinausea medicine: This medicine may be given to calm your stomach and prevent vomiting.


  • Blood, urine, and saliva tests: These are used to test for an H. pylori infection.
  • Urea breath test: You will need to drink a special liquid. Then you will blow air into a bag or balloon. A sample of your breath is checked to see if you have an H. pylori infection.
  • Bowel movement sample: A sample of your bowel movement is sent to the lab to check for the presence of H. pylori.
  • Endoscopy: This test uses a scope to see the inside of your stomach. A scope is a soft, bendable tube with a light and tiny camera on the end. Samples of your stomach contents may be removed and sent to a lab to test for H. pylori.
