Hydrogen and Methane Breath test for SIBO

Quick answers

A hydrogen and methane breath test is a non-invasive test used to help investigate small intestinal bacterial overgrowth, often called SIBO.

The test is arranged through Dr Pranab Gyawali, a UK-trained Consultant Gastroenterologist with over 25 years of clinical experience. It is performed in a JCI-accredited facility in Dubai.

The test measures hydrogen and methane gases in your breath after you drink a test sugar solution. These gases are produced by gut bacteria. Measuring both gases gives a fuller picture than hydrogen testing alone.

This test may be useful if you have bloating, excess gas, abdominal discomfort, diarrhoea, constipation, or IBS-like symptoms where SIBO is being considered.

Cost: a glucose hydrogen and methane breath test costs approximately AED 800 when only the test is required.
Test-only option: if you already have your own gastroenterologist or treating doctor, you can book the test alone and take the result back to your doctor.
Consultation: if consultation and clinical interpretation by Dr Pranab Gyawali are required, the consultation fee is added separately.
Duration: allow up to two hours for the test.
Results: results are usually available promptly and are reviewed clinically before treatment recommendations are made.

Hydrogen and methane breath testing in Dubai

If you are looking for a SIBO test in Dubai, the important point is not just whether breath testing is available. It is whether the test measures the gases that matter and whether the result is interpreted in the context of your symptoms.

Most clinics in Dubai still offer only hydrogen breath testing for SIBO. Combined hydrogen and methane breath testing gives a more complete assessment.

By testing both gases, we can provide a more complete assessment than hydrogen testing alone and use the result to guide more targeted treatment.

This does not mean every patient with bloating or IBS symptoms has SIBO. Breath testing is most useful when the symptoms and clinical history make SIBO a reasonable possibility.

Why does methane matter?

Methane is important because some patients with SIBO do not produce much hydrogen. Instead, methane-producing organisms may be involved.

This matters particularly in patients with constipation, bloating, abdominal distension, or symptoms that have not responded as expected to standard IBS treatment. If only hydrogen is measured, methane-related patterns may be missed.

Video: how the breath test works

In this video, Dr Gyawali explains how hydrogen and methane breath testing can help investigate bloating, constipation and other symptoms associated with SIBO.

Written summary: the test involves drinking a sugar solution and collecting breath samples over a period of time. The breath samples are analysed for hydrogen and methane. The pattern of gas production helps Dr Gyawali decide whether SIBO is likely and what treatment approach may be appropriate.

How the hydrogen and methane breath test can help

The breath test may help when symptoms suggest that bacteria in the small intestine could be contributing to digestive problems.

Common reasons for testing include:

persistent bloating
excess gas
abdominal discomfort
diarrhoea
constipation
IBS-like symptoms
symptoms that return after treatment
symptoms where SIBO is being considered before antibiotics or dietary treatment

A positive result does not automatically mean treatment is simple. The result needs to be interpreted alongside your symptoms, medical history, previous treatment, and any other relevant investigations.

What is SIBO?

SIBO stands for small intestinal bacterial overgrowth.

The small intestine normally contains fewer bacteria than the large intestine. In SIBO, bacteria that usually live mainly in the large intestine are present in higher numbers in the small intestine.

These bacteria can digest sugars and carbohydrates before your body absorbs them. This can produce gas and lead to symptoms such as bloating, distension, discomfort, diarrhoea or constipation.

Cost of hydrogen and methane breath testing

The cost depends on whether you need only the test or whether you also need a consultation.

Breath test only

Approximately AED 800

Consultation required

Consultation fee added separately

Already under another doctor?

You can book the test alone and take the result back to your own doctor.

How to prepare for your hydrogen and methane breath test

Good preparation matters. If preparation is not followed correctly, the result may be harder to interpret.

Important: do not stop prescribed medication without first checking with the clinic or the clinician who prescribed it.

Four weeks before

Check with the clinic if you have recently taken antibiotics, had bowel preparation, or had a colonoscopy.

One week before

Check whether probiotics, laxatives, fibre supplements or motility medicines need to be paused. Do not stop prescribed medicines without advice.

Twenty-four hours before

Follow the restricted diet below.

Twelve hours before

Begin fasting as instructed. Drink water only unless the clinic advises otherwise.

Morning of the test

Avoid smoking, chewing gum and vigorous exercise. Bring any relevant medical information or referral details.

During the test

You will drink the test solution and provide breath samples over the testing period. Allow up to two hours.

Allowed

baked or grilled chicken
baked or grilled turkey
baked or grilled fish
eggs
plain white rice
plain white bread
baked or boiled potatoes
water
plain black tea or coffee before fasting begins

Not allowed

fruit
vegetables and salads
beans and pulses
nuts and seeds
milk and dairy products
wholegrain or high-fibre foods
other grains and cereals
fizzy drinks
mayonnaise
ketchup
honey
mustard
any food not specifically listed as permitted

What happens during the test?

The test is simple and usually causes minimal discomfort.

You will provide a baseline breath sample. You will then drink the test solution. Further breath samples are collected at intervals so hydrogen and methane levels can be measured over time.

The test takes up to two hours.

Results and clinical interpretation

Results are usually available promptly and are reviewed clinically before treatment recommendations are made.

The result should not be read in isolation. A high hydrogen or methane pattern may support SIBO, but symptoms, previous treatment, bowel habit, diet, medication and other conditions all matter.

Treatment options for SIBO

Treatment depends on the result and the clinical picture.

Options may include antibiotics, dietary changes, constipation treatment, review of contributing conditions, or a plan to reduce relapse risk.

Some patients feel noticeably better within a few weeks after treatment starts. The response varies, and symptoms can return if the underlying cause is not addressed.

Benefits of treating SIBO

When SIBO is genuinely contributing to symptoms, treatment may help reduce bloating, gas, abdominal discomfort, diarrhoea or constipation.

The aim is not just to treat a test result. The aim is to understand whether SIBO is part of the reason you feel unwell and whether targeted treatment is likely to help.

Dr Gyawali's view

Breath testing is most useful when it answers a real clinical question.

If a patient has bloating, constipation, diarrhoea or IBS-like symptoms, SIBO may be one possibility. But it is not the only possibility. The value of hydrogen and methane breath testing is that it can make the next step more precise, especially when methane is measured as well as hydrogen.

Take the first step

If you are in Dubai and need a hydrogen and methane breath test for suspected SIBO, you can book the test alone or arrange consultation and interpretation with Dr Pranab Gyawali.
