Hydrogen Test - Xylitol Intolerance Wrocław

Professional Breath Test – Xylitol
Intolerance Wrocław.

 Before performing the xylitol intolerance test, it is necessary to exclude SIBO and IMO by performing a hydrogen-methane breath test with lactulose load.

The breath test with xylitol load is an easy and non-invasive examination that allows detection of hydrogen concentration in exhaled air. Under physiological conditions, the content of this gas in the small intestine is negligible. Its increase allows for the detection of xylitol intolerance.

Hydrogen Test - Xylitol Intolerance Wrocław

How are tests performed at our facility in Wrocław?

The patient inhales air and
exhales into a special bag, which is then handed over to the staff for analysis using the QuinTron Breathtracker SC device. Then, the patient consumes 12.5g of xylitol dissolved in 250ml of water. Xylitol is not sufficiently absorbed and if its intake exceeds absorptive capacity, it moves down the gastrointestinal tract, where bacteria in the colon 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 can be measured in exhaled air. The patient repeats the exhaling procedure every 20 minutes for 120-180 minutes. The hydrogen concentration in the first sample should not exceed 10 ppm. An increase above 20 ppm compared to the baseline sample indicates xylitol intolerance.

What are the indications for conducting breath tests?

  • Indications for the test may include excessive bloating, gas, abdominal pain, diarrhea, loose stools, a feeling of fullness, and nausea. Symptoms may worsen, especially after consuming products such as chewing gum, sweets, gummies, lollipops, jams, nut creams, chocolates, and diabetic products sweetened with xylitol. Xylitol naturally occurs in mushrooms, corn, oats, birch syrup, and many fruits and vegetables. It is also added to medications and syrups.

What are the contraindications for performing hydrogen tests?

An absolute contraindication is reactive postprandial hypoglycemia.

Is a referral required for the test?
