  • Blood tests: A small sample of blood is taken to look for the presence of specific antibodies against the H. pylori
  • Breath test: the patient is given to ingest the tagged carbon molecules. If the bacteria are present they will utilize the molecule and the released by product is released into the blood. Now the breath of the patient is analyzed for the presence of these tagged carbon molecules

Endoscopy: Endoscope is a hollow tube through which contains light and the camera. It is passed down through your throat to look for the inside features of the gut. If ulcer is found, biopsy or part of the ulcer can be taken for the laboratory examination

Diagnosis of helicobacter pylori


If the symptomatic ulcer is left untreated then it can lead to severe complications as follows

Perforation: The ulcer can perforate making a hole in the wall of the stomach. The acidic food content can leak through the perforation into the body cavity from the stomach

Internal bleeding: If an ulcer is located near a blood vessel and then the blood can ooze out leading to black stools or vomit in the blood. Gradually iron deficiency anemia will develop.

Peritonitis: The leaked contents irritate the peritoneum and the organs present in the cavity of the body.

Stomach cancer: It is the extreme complication of chronic stomach ulcer

Complications of Helicobacter pylori


Asymptomatic H. pylori infection doesn’t come to notice and doesn’t require treatment. The management of symptomatic infection includes treatment of underlying condition by giving antibiotics and reducing the signs and symptoms


Triple therapy: the drug therapy is known as triple therapy as it includes two different antibiotics and a proton pump inhibitor which blocks the acid secretion as in reduced acid concentration the antibiotics works more effectively.

Clarithromycin and amoxicillin are the common antibiotics prescribed

Lansoprazole, rabeprazole or pantoprazole are the common Proton pump inhibitors


For many people having asymptomatic infection, H. pylori rarely causes trouble. The outlook of patients having diseases associated with the bacteria is good after taking the medications. Some people need a second round of triple therapy to completely eradicate the bacteria. Chances of developing stomach cancer is rare and seen in chronic patients.
