What is SIBO?

Why Breath Testing for SIBO?

SIBO happens when excessive bacteria grow in the small intestine, producing gases like hydrogen and methane as they break down undigested food. These gases can cause symptoms like bloating and abdominal pain.
Excessive gas production can be a sign of SIBO. When fermentation happens too fast or too much, it leads to more gas* and may indicate that the digestive system is out of balance. *Notably hydrogen and methane
Once produced, gases enter the bloodstream and travel to the lungs, where they are exhaled in your breath. With FoodMarble, you can measure these fermentation levels to monitor your SIBO progress and improve digestion.

FoodMarble AIRE 2 FAQs

SIBO stands for Small Intestinal Bacterial Overgrowth. It occurs when excessive bacteria grow in the small intestine, leading to symptoms like bloating, gas, abdominal pain, diarrhea, or constipation. SIBO can interfere with nutrient absorption and disrupt the gut microbiome.

FoodMarble’s AIRE 2 device measures hydrogen and methane gas levels in your breath. These gases are produced when bacteria ferment food in your gut. By tracking them on the app after meals or food challenges, you can detect abnormal fermentation patterns: a key indicator of SIBO and better understand which foods trigger symptoms.

Traditional SIBO tests are often done in clinics and only provide a snapshot in time, they are also costly. With FoodMarble, you can test from home, multiple times over the course of your day and week, using real-time technology. This allows for personalized and continuous tracking of your digestive response, which may offer deeper insights. Also, digestive patterns can fluctuate throughout the years.

Yes. If you’ve been diagnosed with SIBO, AIRE 2 can help you monitor progress, track symptom triggers, and assess how your digestion changes during treatment or dietary adjustments. It’s also really helpful for post-treatment relapse monitoring and making sure you are on track.

The Food Intolerance Kit includes four FODMAP test sachets: lactose, fructose, inulin, and sorbitol. Each sachet lets you test your tolerance to a different type of fermentable carbohydrate that can trigger symptoms in SIBO and IBS. The process is guided through an interactive app experience, making it easy to follow. Your results can support more personalized dietary decisions helping you avoid unnecessary restrictions.

Yes, FoodMarble’s technology has been used in clinical research settings, including studies on IBS and fermentation patterns. The AIRE 2 uses validated hydrogen and methane sensors, and the testing process aligns with established breath testing protocols.

You can use the device multiple times daily, especially after meals or during testing protocols. For SIBO tracking, we recommend consistent usage over several weeks to establish patterns and identify specific food responses.
