H2 breath test



The H2 breath test is performed for the investigation of patients with digestive disorders such as bloating, diarrhea and nausea. Certainly, these symptoms can cause heart problems, for example cardiac arrhythmias.


The breath test can provide information on disorders of the digestion of food components in the gut. In the cleavage of carbohydrates in the intestine arises hydrogen (H2). The concentration of the hydrogen is measured via the exhaled air. Depending on function or intolerance, a certain sugar (lactose, glucose, fructose, lactulose, sucrose or xylose) (lactose, glucose, fructose, lactulose, sucrose or xylose) is given.

- Determination of a fasting value

- Drinking liquid sugar test

- Measuring the concentration of hydrogen every 30 minutes
