The H. pylori breath test is a simple and safe test used to detect an active H. pylori infection.
Helicobacter pylori (or H. pylori) is a bacteria that can infect the stomach or duodenum (first part of the small intestine). If left untreated, H. pylori bacteria can cause gastritis (an inflammation or irritation of the stomach lining) and duodenal or gastric ulcers. In addition, infection with H. pylori increases the risk of other diseases and is also a risk factor for gastric cancer.
Accurate detection of H. pylori is the first step toward curing stomach and intestinal ulcers, and preventing the development of more serious gastrointestinal problems.
During the test, you will be asked to exhale into a balloon-like bag. The air you breathe into this bag is tested to provide a basis for comparison (called a baseline sample). You will then be asked to drink a small amount of a pleasant lemon-flavored solution. Fifteen minutes after drinking the solution, a second breath sample will be taken. The air you breathe into this bag is tested for an increase in carbon dioxide.
Be sure to tell your doctor if you are allergic to any medicines or if you are phenylketonuric.
Please note:* *Do not stop taking any other medicine without first talking with your doctor.
One hour before the test, do not eat or drink anything (including water).
A healthcare provider will explain the procedure in detail and answer any questions you might have. The procedure lasts about 20 to 30 minutes.
