Hydrogen Lactulose Breath Test

Hydrogen lactulose breath test
There is now a method called hydrogen lactulose breath test, which is used to detect gastrointestinal diseases. The method uses lactulose as bait and takes it. Lactulose is difficult to absorb in the small intestine. After entering the large intestine, it is yeasted by the intestinal flora and generates hydrogen.

The subject first fasts, then drinks the liquid containing lactulose, and regularly collects breath samples to measure the amount of hydrogen in it. If the intestinal transmission rate is abnormal, or colonic bacteria migrate to the small intestine, the measured hydrogen concentration varies at a specific time.

The advantages of this test are non-invasive and convenient. There is no need for laparotomy and no risk of radiation, and the subject is easy to accept. It can help doctors break off diseases such as excessive growth of small intestine bacteria and intestinal motility disorders, which is of great significance in the diagnosis of gastrointestinal diseases. According to the results of the test, doctors can determine precise treatment strategies for patients to help them recover from health early.
