The hydrogen and methane breath test is a simple, non-invasive medical test that measures the level of hydrogen or methane gas that you exhale after drinking a mixture of water and glucose. A rapid hike in exhaled methane or hydrogen may indicate bacterial overgrowth in your small intestine. The test is usually used to confirm or rule out common digestive issues, such as SIBO (small intestine bacterial overgrowth) and lactose intolerance.
The test can help your physician confirm the diagnosis of SIBO when beneficial bacteria from your large intestine have moved into your small intestine, where they do not belong. In a healthy digestive system, the carbohydrates and sugars that you consume are predigested before they reach the bacteria in your large intestine. If they have not been completely digested by then, the anaerobic gut bacteria in the colon will digest them, converting them into gas.
This gas in your colon is absorbed into your blood and carried into your lungs, where it is expelled through your breath. That is how your breath can indicate what is going on in your gut.
Advanced Hydrogen and Methane Breath Testing in Dubai
Most clinics in Dubai still offer only hydrogen breath testing for SIBO. At our clinic, we go a step further—offering combined hydrogen and methane breath testing to give you a more complete and accurate diagnosis.
Methane-producing bacteria are often missed by standard hydrogen-only tests. These bacteria are commonly linked to constipation-dominant IBS, excessive bloating, and unexplained abdominal discomfort. By testing for both gases, we can identify more subtle cases of SIBO or carbohydrate intolerance—leading to more targeted and effective treatment.
Why Does Methane Matter?
Many patients with bloating, constipation, or IBS symptoms have methane-dominant overgrowth—which can’t be detected with hydrogen testing alone. If you’ve had a hydrogen test elsewhere that came back “normal,” you could still have methane SIBO that was missed.
By testing both gases, we give you the complete picture—so your treatment can finally work.
How the Hydrogen and Methane Breath Test Can Help You with Gut Issues
This is a simple guide on understanding Small Intestinal Bacterial Overgrowth (SIBO) and how the hydrogen and methane breath test can help diagnose and treat this often-overlooked condition.
What is SIBO?
Small Intestinal Bacterial Overgrowth (SIBO) occurs when there is an excessive growth of bacteria in the small intestine. This imbalance can lead to uncomfortable symptoms such as:
Bloating: Excess bacteria ferment food in the small intestine, producing gas that causes a swollen and uncomfortable feeling in the abdomen.
Gas: The fermentation process by the bacteria produces hydrogen and methane gases, leading to increased flatulence and belching. Diarrhea: The excessive bacteria can disrupt normal digestion and absorption, leading to loose stools or diarrhea as food passes through the intestines more quickly.
Abdominal Pain: The accumulation of gas and the movement of poorly digested food through the intestines can cause cramping and abdominal discomfort.
If left untreated, SIBO can cause nutrient malabsorption, leading to more serious health issues.
Treatment Options for SIBO
Once diagnosed, treatment for SIBO can vary and may include:
Antibiotics: To reduce bacterial overgrowth
Dietary Changes: To limit fuel for the bacteria
Probiotics: To restore a healthy balance of gut bacteria
Benefits of Treating SIBO
Treating SIBO can lead to:
- Reduced symptoms like bloating and abdominal pain
- Improved nutrient absorption
- Overall enhanced digestive health
- Many patients report feeling significantly better within just a few weeks of starting treatment.
How the Hydrogen and Methane Breath Test Works
The hydrogen and methane breath test that we do here in Dubai is a non-invasive procedure designed to diagnose SIBO. Here’s how it works:
Preparation: Follow a special diet the day before the test and fast overnight to ensure accurate results.
The Test: Drink a sugar solution, then breathe into a device at regular intervals.
Detection: Bacteria in the small intestine produce hydrogen or methane when they digest sugar. High levels of these gases in your breath can indicate SIBO.
What to Expect During the Test
Duration: The test typically takes about 2 to 3 hours 90 minutes.
Procedure: It’s simple and straightforward with minimal discomfort.
Treatment Options for SIBO
Once diagnosed, treatment for SIBO can vary and may include:

Dietary Changes: To limit fuel for the bacteria
Probiotics: To restore a healthy balance of gut bacteria
Benefits of Treating SIBO
Treating SIBO can lead to:
- Reduced symptoms like bloating and abdominal pain
- Improved nutrient absorption
- Overall enhanced digestive health
- Many patients report feeling significantly better within just a few weeks of starting treatment.
Quick Turnaround for Results
Most patients can expect to receive their results the same day, allowing for a prompt start to treatment.
Take the First Step Towards Better Digestive Health
