Helicobacter pylori breath test in Medellín, Colombia

What is the Helicobacter pylori breath test?

It is a simple, non-invasive test that detects an active Helicobacter pylori infection, a stomach bacterium that can cause gastritis and ulcers and, over time, raise the risk of stomach cancer. A breath sample is taken, you drink a solution containing labeled urea, and a second sample is taken to compare them.

When is it ordered?

For burning or pain in the upper stomach, feeling full quickly, nausea, or a diagnosis of ulcer or gastritis. Also for people with a family history of stomach cancer and, importantly, to confirm the bacteria was eliminated after treatment.

How should you prepare?

Preparation is key for a reliable result. Usually you will be asked to:

Stop acid-reducing medications such as omeprazole, esomeprazole or similar for the 2 weeks before.

Not have taken antibiotics or bismuth-containing medications in the last 4 weeks.

Arrive fasting, usually for 6 hours, and avoid smoking before the test.

Check with your doctor before stopping any medication and follow the lab's exact instructions.

When should it be repeated after treatment?

It is recommended at least 4 weeks after finishing antibiotics, with the same preparation. Testing earlier can give a false negative.

Is it safe?

Yes. It is painless, takes 30 to 60 minutes, and the carbon-13 version is not radioactive, so it can be done in children and pregnant women. A gastroenterologist or general practitioner interprets the result and decides on treatment.
