Hydrogen and methane breath test
Gold-standard for SIBO diagnosisWhat you need to know about our SIBO Test
SIBO (Small intestinal bacterial overgrowth) is a common condition where excess bacteria in the small intestine cause symptoms such as bloating, diarrhoea and constipation.
Our SIBO Breath Test is a simple home test where you collect breath samples after drinking lactulose sugar-solution. You'll send the breath samples to our lab for analysis of hydrogen and methane levels. We'll explain whether your results suggest SIBO in your online doctor's report.
You'll also get a consultation with one of our gut-health doctors to discuss your results and treatment options.
What is SIBO (small intestial bacterial overgrowth)?
SIBO is a common gut condition where there are an excess of bacteria in the small bowel. These bacteria metabolise carbohydrate in your diet to produce gasses that lead to symptoms such as bloating. Bacteria can also affect the absorption of fat and vitamins leading to diarrhoea and deficiencies.
SIBO symptoms?
SIBO can cause gut symptoms such as:
- Stomach pain
- Diarrhoea
- Bloating
- Gas
- Constipation
SIBO symptoms aren't limited to the gut. Symptoms could also include:
- Fatigue
- Brain fog
- Joint pain
- Skin rashes
What other conditions is SIBO linked to?
As we learn more about the gut-brain axis and the gut-skin axis, we're discovering that SIBO is linked to a number of other conditions. These include:
- Irritable bowel syndrome (IBS)
- Fibromyalgia
- Chronic fatigue syndrome (CFS)
- Rosacea
- Psoriasis
How to test for SIBO?
- Follow a low-fermenting diet for 24 hours.
- Take a baseline breath sample
- Drink a solution of lactulose, a carbohydrate that is not absorbed by your gut but is metabolised by bacteria
- Take 6 breath samples over 150 minutes.
- A raised level of hydrogen or methane in your breath samples can indicate SIBO.
SIBO treatment?
The goal of SIBO treatment is not to eradicate all the bacteria from the small intestine. Rather, we need to modulate them in a way that improves symptoms.
Because SIBO has many different causes, there's no one-size-fits-all treatment. We need to tailor the treatment to the individual. Once you've received your result, you'll be able to book a consultation with one of our gut-health experts to discuss your results and treatment options (extra charges apply).
We find that a holistic approach to SIBO treatment produces the best results and minimises relapse. This involves:
- Addressing the underlying cause
- Lifestyle change
- Optimising diet
- Anti-microbial treatment - this can be with antibiotics, herbal antimicrobials or a combination of both.

SIBO Test FAQs
You'll need to prepare for your SIBO Breath Test by:
- Following a low-fibre diet for 24 hours before the test
- Fasting for 12 hours before the test
- Avoid antibiotics or antimicrobials for 4 weeks before the test
- Avoid laxatives and antacids (e.g. Renee, Gaviscon) 2 weeks before the test
- Stop pro- and pre-biotics 2 days before the test
We'll go through all these instruction in detail with your test kit.
Your samples are sent to our specialist lab partner in Europe for analysis. It usually takes about 2-5 days for samples to arrive.
Once the lab have received your samples, we generally have results in a few days. However, at most it can take up to 14 days to get your results.
The hydrogen and methane breath test following lactulose is the recommended method for diagnosing SIBO. However, as with any test, it can give false positive and false negative results.
Studies have shown that if you have a positive SIBO breath test then there's about 60-70% chance that your symptoms will respond to SIBO treatment. On the other hand, if you have a negative SIBO breath test result, then the chance that you'll respond to treatment is only about 20%.
Yes, our gut-health doctors can prescribe treatment for SIBO after reviewing your test results. Once you receive your rsults, you can book a consultation with one of our gut-health experts to discuss your results and treatment options (extra charges apply).
