SIBO Breath Test
SIBO Breath Test
Bloating, excessive gas and bowel changes can sometimes be associated with microbial overgrowth within the small intestine. SIBO Breath Test at Yoyime Wellness Clinic in Dubai provides a non-invasive assessment using a standardised carbohydrate substrate followed by timed measurement of hydrogen and methane in the breath. Our clinician first reviews symptoms and risk factors to determine whether testing is appropriate. Preparation, sample timing and interpretation are important because altered intestinal transit and other factors can influence breath test results.
Benefits of SIBO Breath Test
Non Invasive Testing
Measures Hydrogen and Methane
Supports Targeted Investigation
Recommended for Patients With

Persistent Abdominal Bloating

Excessive Gas Symptoms

Suspected Intestinal Overgrowth
Step-By-Step Procedure - SIBO Breath Test
Symptom Assessment
Discuss bloating, gas, bowel changes and other relevant gastrointestinal symptoms.

Risk Review
Our clinician considers medical history and factors that may increase overgrowth risk.

Suitability Confirmation
Breath testing is selected when symptoms and clinical context make it appropriate.

Preparation Guidance
Dietary, fasting and medication instructions are provided before the test.

Baseline Sample
An initial breath sample establishes baseline hydrogen and methane measurements.

Test Substrate
The specified glucose or lactulose solution is consumed according to protocol.

Timed Samples
Breath samples are collected at defined intervals while symptoms may also be recorded.

Results Review
Our clinician interprets gas patterns within the clinical context and recommends next steps.

Frequently Asked Questions
SIBO Breath Test
Yoyime's SIBO Breath Test in Dubai measures hydrogen and methane after ingestion of a specified carbohydrate substrate to support assessment for suspected small intestinal microbial overgrowth.
SIBO refers to excessive bacterial numbers or an abnormal bacterial population within the small intestine that may be associated with gastrointestinal symptoms in selected patients.
Modern testing commonly measures both hydrogen and methane because methane information can be particularly relevant in patients with constipation related symptoms.
Depending on the testing protocol, glucose or lactulose may be used as the test substrate. Both are established non-invasive approaches used in SIBO breath testing.
The general medical guidance considers a hydrogen rise of at least 20 parts per million above baseline by 90 minutes supportive of SIBO in the appropriate testing context.
Methane of at least 10 parts per million is considered methane positive in consensus criteria. Methane positivity is increasingly described as intestinal methanogen overgrowth rather than bacterial overgrowth.
No. SIBO breath testing evaluates gas production associated with the small intestine, whereas GI-MAP analyses selected microbial DNA within a stool sample.
The technology is similar, but the substrate and interpretation differ. Lactose or fructose breath testing belongs within targeted food intolerance assessment rather than the dedicated SIBO service.
Yes. Diet, fasting, medicines and recent gastrointestinal treatments can affect results, so the laboratory preparation protocol should be followed carefully.
Cost depends on the breath testing protocol and consultation requirements. At Yoyime, our team explains preparation, testing and associated costs beforehand.
