Procedure diagram

What is SIBO and IMO?

Methanogen Overgrowth. SIBO refers to an overgrowth of bacteria in the small intestine, while IMO refers to an overgrowth of archaea in the small intestine. They produce hydrogen and methane, which can cause gastrointestinal symptoms such as bloating, gas, loose stools, or constipation.


SIBO and IMO can be diagnosed using a hydrogen-methane breath test, which is an easy and non-invasive examination. It allows for the detection of hydrogen and methane concentrations in exhaled air.


Treatment involves the use of antibiotics, prokinetic substances that stimulate intestinal peristalsis and the migrating myoelectric complex, probiotic supplementation, FODMAP diet, and changes in dietary habits.


How can you perform a SIBO test?

Do a home test.

Purchase a mail-in test from our online store, send us the samples, and we will analyze them within 1-2 business days.

Frequently asked questions

What are the contraindications for performing breath tests?

An absolute contraindication is hereditary fructose intolerance and postprandial hypoglycemia, also known as reactive hypoglycemia.

Is a referral for the test required?

No, the test does not require a referral from a doctor.

Is drinking lactulose difficult?

No, it is a slightly sweet solution that is easy to drink. There are practically no side effects from it, except for bloating and gas in the case of SIBO and IMO.

What kind of device is used for the test?

The test is performed on the QuinTron Breathtracker SC device. QuinTron is a device used for research studies in the best research centers worldwide.

Do you create individual FODMAP diet meal plans?

Yes, if you do not have your own dietitian, we will create a FODMAP meal plan according to your preferences.

How is the breath test performed?

The patient breathes into a special bag, and then the sample is analyzed on the QuinTron Breathtracker SC device.
Then, the patient consumes 10g of lactulose solution (dissolved in 200 milliliters of water), which, as a synthetic disaccharide consisting of galactose and fructose, is not absorbed in the small intestine and is fermented by gut bacteria.
Lactulose moves down the digestive system, and bacteria break it down into short-chain fatty acids, hydrogen, and carbon dioxide.
Hydrogen dissolves in the blood and is transported to the lungs, where its presence in exhaled air can be measured. Hydrogen can also be used by archaea to produce methane. The patient repeats the procedure of exhaling air every 20 minutes for 3 hours.
If there is an elevated hydrogen and/or methane growth in the appropriate section of the small intestine, it may indicate bacterial overgrowth in the small intestine (SIBO) or archaea (IMO).


Professional service

Our SIBO TESTS offer includes not only conducting tests, but also individual
consultations with experienced specialists who will answer all questions regarding
the results and recommend appropriate actions in case of confirmed SIBO, IMO, and

For the breath test, please bring along blood tests, thyroid ultrasound results,

positive impact and prevent the recurrence of this disease.
