Hydrogen-methane breath test for SIBO and IMO in Wroclaw.

Hydrogen-methane breath test for SIBO and IMO in Wroclaw.

This is an easy and non-invasive examination that allows for the detection of
hydrogen and methane levels in exhaled air.

Under physiological conditions, the presence of these gases in the small intestine is negligible.

An increase in gas during the test allows for the detection of Small Intestinal Bacterial Overgrowth (SIBO) and Intestinal Microbial Overgrowth (IMO), which is an overgrowth of bacteria and/or archaea in the small intestine.

Hydrogen-methane breath test for SIBO and IMO in Wroclaw.

How are tests conducted at our facility in Wrocław?

The patient inhales air into their lungs and exhales into a special bag, and then the staff examines the sample in the QuinTron Breathtracker SC machine. Then, they consume 10 grams of lactulose solution, which is a synthetic disaccharide composed of galactose and fructose that is not absorbed in the small intestine and undergoes fermentation by gut bacteria. Lactulose moves down the digestive system, and bacteria break it down into short- chain fatty acids, hydrogen, and carbon dioxide. Hydrogen dissolves in the blood and
is transported to the lungs, where its presence in exhaled air can be examined. Hydrogen can be used by archaea to produce methane. The patient repeats the air exhaling procedure every 20 minutes for 3 hours. If there is an elevated increase in hydrogen and/or methane in the appropriate segment of the small intestine, it may indicate bacterial overgrowth in the small intestine (SIBO) and/or archaeon overgrowth (IMO).

What are the indications for conducting breath tests?

Indications for the test can include excessive bloating, gas, abdominal pain, diarrhea, loose stools, constipation, reflux, heartburn, unpleasant breath odor, feeling of overflow, fullness in the upper abdomen, headaches, and anemia. Symptoms may worsen especially after consuming products such as onions, garlic, leeks, cauliflower, and apples. After a longer period of illness, symptoms may worsen even after drinking a glass of water
on an empty stomach.

What are the contraindications for performing hydrogen-methane tests?

An absolute contraindication is hereditary fructose intolerance and postprandial hypoglycemia, also known as reactive hypoglycemia.

Is a referral for the test needed?
