If sugar intolerance is suspected
H2 breath test at JUVENIS
The hydrogen breath test (H2 breath test) is carried out in cases of suspected sugar intolerance (lactose intolerance, fructose malabsorption, sorbitol intolerance, SIBOS). The various sugars must first be broken down in the intestine so that they can then be transported through the wall of the small intestine into the blood.
If one of these mechanisms does not work, the sugar cannot be absorbed and subsequently reaches the large intestine, where it is metabolized by the intestinal bacteria located there. This produces H2 (hydrogen), which can be measured with the JUVENIS breathing apparatus, and CO2 (carbon dioxide), which is responsible for the abdominal symptoms.
At JUVENIS, the non-invasive H2 breath test is carried out by experienced nutritionist Dr. Daniela Themmer. If the symptoms are not recognized, they can become chronic and cause great suffering for affected patients. With this simple method, we can help and contribute to your health.

Treatment procedure
After you, as a patient of JUVENIS, have been informed about the preparation for the test (which varies depending on the suspicion), you will come to the surgery on the day of the test on an empty stomach.
After a so-called blank value measurement, the sugar to be tested is dissolved in water and then drunk by the patient.
This is followed by 4-5 breathing measurements (similar to a lung function measurement) at 30-minute intervals.
A sugar utilization disorder can be confirmed or ruled out based on the values of the measurement curve. You will receive your results on the same day.
Important: No more appointments on the test day!
There should be at least 2 weeks between the individual tests.
