Why have the test at Endomedix?
-
Accurate diagnostics
The H₂ breath test is based on detecting fermentation. If fructose is not absorbed in the small intestine, bacteria in the large intestine produce hydrogen gas, which our device measures precisely in the air you breathe out. No needles or unpleasant procedures are needed.
-
Professional thoroughness and protocol
With us, the measurement is not just about numbers. During the 180-minute test (in which you blow into the device every 20 minutes), we also continuously record any physical symptoms that appear, so the diagnosis rests on several pillars and is highly reliable.
-
A calm, comfortable environment
Although the test takes time (3 hours), we provide a calm environment. As most of the process is waiting, all our patients need to do is relax – with a good book, time flies with us.
How should you prepare for the fructose breath test?
For an accurate result, preparation is critical here: breaking even a single rule can distort the measurement.

Did you know?
Five questions and answers about the fructose breath test.
-
Did you know that fructose intolerance is not only about fruit?
Many soft drinks, ketchup and ready meals contain glucose-fructose syrup, which can trigger the same unpleasant symptoms.
-
Did you know that the breath test measures the work of your gut bacteria?
Our bodies do not produce hydrogen, so if the device detects the gas, it is clear evidence that the sugar has not been properly absorbed.
-
Did you know that lactose and fructose sensitivity often go hand in hand?
If one of your tests is negative, it is worth having the other one done too, to get a complete picture of your digestive health.
-
Did you know that the examination fee can also be paid from your health fund account?
This means the cost of your tests can be reduced through tax relief.
-
Did you know that the right diet after diagnosis can bring a dramatic improvement?
By consciously managing their fructose intake, most patients become completely free of complaints within a few weeks.
