History of the disease

When SIBO occurs, there is an overgrowth of bacteria that speeds up the natural fermentation process during digestion. This condition causes abdominal bloating and pain, bowel changes, nausea, and other unpleasant symptoms. The disease can occur on its own or in conjunction with other conditions, such as irritable bowel syndrome. SIBO used to be thought to occur in a small number of people, mostly with upper gastrointestinal tract abnormalities and motility disorders. However, the disease is now becoming increasingly common. Studies show that it affects 15 % of generally healthy people.

How the tester works

The AIRE connects to an app on your smartphone via Bluetooth. The test results appear in real-time, allowing you to quickly understand how the chosen diet and treatment affects a person's digestive health. The accuracy of AIRE testing also makes remote diagnosis and monitoring of the course of disease possible.

Compare

The clinical hydrogen breath test, which is the gold standard for determining SIBO, requires patients to spend many hours in the clinic. Mail-order kits for this test make the test easier for patients, but both clinical and mail-order tests have limitations in accuracy. Additionally, the conventional breath test requires the patient to consume lactulose, a synthetic sugar used to treat constipation. The tester then reconstructs and quantifies the patient's exhaled hydrogen produced by the processing of lactulose by gut bacteria. The advantage of AIRE is that it measures and analyzes the concentration of hydrogen in the breath after the patient has eaten foods typical of their normal diet. This means that the user can easily repeat the test at home with the results immediately available. The dynamics of changes in results provide more information than a single test and allow for more accurate tracking of symptoms.

Tested successfully

Food Marble's device recently received clinical validation in trials at Johns Hopkins Medical Center in Baltimore, Maryland. AIRE performed better than breath test kits commonly used to diagnose bacterial overgrowth syndrome in the small intestine.
