Information

How to prepare

The hydrogen breath test is a safe and non-invasive method used to assess the activity of the gut microbiota and detect potential changes in the small and large intestines. During the test, the patient drinks a glucose solution, and the amount of hydrogen in the breath is measured at specific intervals over several hours. This gas is produced when bacteria in the intestines ferment glucose, and elevated levels of it indicate a possible overgrowth of bacteria in the small intestine (SIBO).

The test helps detect imbalances in the intestinal bacterial flora, which can cause symptoms such as bloating, increased gas production, abdominal pain, or diarrhea. It can also be used to monitor the effectiveness of treatment, for example, after a course of antibiotics, and to assess the restoration of the intestinal microbiota.

The test usually takes 2–3 hours.

How should I prepare for the exam?

  • Diet: The day before the test, you must follow a special diet low in fiber and carbohydrates—avoid legumes, grains, fruits, vegetables, dairy products, as well as sweetened and carbonated beverages.
  • Medications: You must not take antibiotics or other medications that may affect bowel function for at least 2 weeks before the test. If you are taking any medications, you must consult your doctor about discontinuing them.
  • Additional restrictions: On the day of the test, you must arrive on an empty stomach and avoid smoking, alcohol, and intense physical activity.

The hydrogen glucose test is more specific (fewer false-positive results); it detects bacterial overgrowth in the upper part of the small intestine but may not detect overgrowth in the lower sections.
