H2 breath test in gastroenterology: when is it useful?
The H2 breath test is carried out if there is a suspicion of carbohydrate intolerance or malabsorption. These occur when certain food components are not sufficiently digested or absorbed in the intestine due to an enzyme deficiency. The undigested carbohydrates reach the large intestine, where they are broken down by bacteria to form gas. Typical symptoms are flatulence, abdominal pain and diarrhea. Non-specific symptoms such as tiredness, headaches, dizziness or nausea may also occur.
Which intolerances can be detected with the H2 breath test?
- Lactose intolerance: Those affected react to dairy products such as cow's milk, yoghurt or soft cheese.
- Fructose malabsorption: Fruit sugar (fructose) is contained in fruit, vegetables and many ready-made products.
- Sorbitol intolerance: Sorbitol is a sweetener that is found in many sugar-free and "light" products.
When is the H2 breath test still used?
- Small intestinal bacterial overgrowth (SIBO): An unusual accumulation of bacteria in the small intestine can lead to flatulence and diarrhea.
- Determination of the orocecal transit time: This involves analyzing the speed at which food mash is transported through the digestive tract.
How does the H2 breath test work?
During the test, the patient drinks a defined amount of a certain sugar. The hydrogen content (H2) in the exhaled air is then measured at set times. An elevated H2 value indicates that undigested carbohydrates are being broken down by intestinal bacteria.
What factors can influence the test result?
- Previous use of antibiotics or a colonoscopy.
- Smoking or chewing gum before and during the test.
- Taking certain medications.
What to do if the test result is positive?
If the test shows an intolerance, the type of sugar in question should be avoided or replaced with suitable enzyme preparations. In the case of lactose intolerance, for example, lactase can be taken in tablet form.
Is the H2 breath test also useful for irritable bowel syndrome?
The H2 breath test can help to rule out other causes of irritable bowel syndrome. Studies show that many irritable bowel syndrome patients benefit from a low FODMAP diet, which can be optimized with a breath test.
Where can an H2 breath test be carried out in Switzerland?
The H2 breath test can be carried out easily in a doctor's surgery. It is non-invasive, takes around two to three hours and can also be used on children.

FAQ questions: Colorectal cancer screening and bowel screening.
Who carries out the screening?
Colonoscopy can be carried out on an outpatient basis in a gastrointestinal practice in almost all cases. A colonoscopy may only be performed by doctors who have completed special training for this examination. To ensure good quality, gastroenterologists must prove that they have performed a specified minimum number of colonoscopies per year. There are also special hygiene regulations and quality standards for practices and clinics that carry out colonoscopies, compliance with which is monitored.

Kann man SIBO und IMO mit demselben Test nachweisen?
Zur Beurteilung einer methanassoziierten intestinalen Methanogen-Überwucherung (IMO) ist zusätzlich eine Methanmessung erforderlich. Ein reiner H₂-Test reicht dafür nicht aus.
Ist bei Reizdarm immer ein Atemtest notwendig?
Nein. Die Diagnose eines Reizdarmsyndroms erfordert nicht routinemässig einen Atemtest. Bei bestimmten Verdachtsdiagnosen kann die Untersuchung jedoch ergänzende Informationen liefern.
Muss ich bei einer Laktoseintoleranz vollständig auf Milchprodukte verzichten?
Meist nicht. Die verträgliche Laktosemenge ist individuell unterschiedlich. Viele Betroffene können kleine Mengen Laktose oder laktosefreie Milchprodukte problemlos konsumieren.
Benötige ich für den Atemtest eine ärztliche Überweisung?
Ob eine Überweisung notwendig ist, hängt unter anderem vom Versicherungsmodell ab. Die Untersuchung sollte aufgrund einer konkreten medizinischen Fragestellung erfolgen.
