A breathing urine test is a simple, painless test that checks for an infection in your stomach called Helicobacter pylori (or H. pylori). Despite its name, it does not involve urine — you breathe into a bag after drinking a special liquid. The test measures a gas in your breath to see if the bacteria are present.
Key facts
This test is commonly used when a person has stomach pain, indigestion, or an ulcer that might be caused by H. pylori. The infection itself is common worldwide, especially in areas with less access to clean water.
Anyone can have H. pylori infection, but it is more common in children and older adults. People living in crowded conditions or areas with poor sanitation are at higher risk.
A healthcare provider will first ask about your symptoms and medical history. If they suspect H. pylori, they may order a breathing urine test (urea breath test) or a stool test. The breath test is very reliable and often the first choice.
For the urea breath test, you will be asked not to eat or drink for at least 6 hours before. You may need to stop certain medicines for 1‑2 weeks beforehand (your doctor will tell you which ones). The test itself is painless and takes about 30 minutes. You drink a mild liquid, then after about 15 minutes you breathe into a collection bag. The results are usually available within a few days.
If the test shows H. pylori infection, treatment aims to kill the bacteria and heal the stomach lining. A typical treatment uses a combination of two or three antibiotics plus a medicine that reduces stomach acid. Your doctor will choose the best regimen based on your health and local resistance patterns.
Doctors usually prescribe a combination of antibiotics (such as amoxicillin and clarithromycin, or metronidazole and tetracycline) along with a proton pump inhibitor (a medicine that lowers stomach acid). Sometimes bismuth subsalicylate is added. The exact combination depends on your situation. Treatment lasts 10‑14 days. After finishing, a repeat breath test is often done to confirm the infection is gone.
With successful treatment, most people feel better within a few weeks. You should avoid triggers like smoking, excessive alcohol, and stress, which can worsen stomach issues. Complete the full course of treatment even if symptoms disappear.
During treatment, eat bland, easy‑to‑digest foods like rice, bananas, applesauce, and cooked vegetables. Avoid spicy, acidic, or fatty meals. After healing, a balanced diet rich in fruits, vegetables, and whole grains can help keep your stomach healthy. Gentle exercise like walking can improve digestion, but avoid heavy exertion if you feel unwell.
There is no vaccine for H. pylori, but you can lower your risk by practicing good hygiene. Wash your hands often, drink safe water, and avoid eating undercooked or unwashed food. If you live with someone who has H. pylori, they should complete treatment and avoid sharing personal items until the infection is gone.
Routine screening for H. pylori is not recommended for everyone. Your doctor may suggest testing if you have ongoing stomach symptoms, a family history of stomach cancer, or if you come from a region where the infection is common.
The outlook for H. pylori infection is very good. With proper treatment, more than 90% of people are cured. Ulcers usually heal, and symptoms improve. After treatment, the risk of complications like cancer drops significantly. Regular follow‑up with your doctor and a healthy lifestyle can keep your stomach healthy for years.

Surgery is rarely needed for H. pylori infection. It may be considered only if the infection causes a serious complication like a perforated ulcer (a hole in the stomach wall) or severe bleeding that cannot be controlled by other means.
Having a chronic stomach issue can be frustrating and may cause anxiety about eating or social activities. It is normal to feel this way. Talk to your doctor or a counselor if you feel overwhelmed. Most people recover fully and return to normal life after treatment.
