Coeliac disease is an auto-immune condition, which isn’t very common. It affects 1% of the population or so. AIRE measures gut fermentation levels, which is unrelated to Coeliac disease and gluten intolerance.

If you think that you may have an intolerance or sensitivity to gluten, it would be best to get this tested with your physician. Gluten intolerance is an immune response to gluten proteins. Our products test for different biomarkers and wouldn’t be the ideal tool for testing gluten intolerance.

Yes. If you purchase the food intolerance testing kit, you can test your reaction to four common FODMAPs including lactose, fructose, sorbitol and inulin. If you suspect you may have lactose intolerance, you can select this as your first test.

AIRE 2 measures both hydrogen and methane gases in your breath. These gases are produced during fermentation in the gut when certain foods aren’t fully digested. By measuring both, AIRE 2 provides more accurate, real-time insights into how your body responds to different foods, helping you better understand your digestive health.

To achieve success with our products, we recommend one device per user.

Our devices can be used by children under the guidance of an adult. Use for children is exactly the same as it is for adults.

The quantities of the FODMAP substrates are also safe for children.

AIRE 2 is not suitable for use by babies / toddlers, because of the breathing technique required to perform a breath test.

Most people will tend to take 4-6 weeks to get a good handle on which foods are most suited to their digestion. There are some people who just want to test one or two food components, which is valuable and can be done more quickly. Then, on the other end of the spectrum, some people will track their response to food over several months or will start using the device again after a lifestyle change (e.g. change in diet) as that can often affect how you digest food.

Yes, it’s possible for us to share your results securely with your doctor, as long as we get your consent. Assuming your doctor is comfortable to proceed, just send an email to clinical@foodmarble.com with contact details for your doctor and we’ll take it from there.

By making breath testing a part of your day, you can discover a lot about your gut. If you manage to take between 8-10 breath tests each day, you are doing an excellent job. Here’s a good approach to daily breath testing:

• Take a baseline breath test once you wake up, after brushing your teeth and before eating food.
• Wait until one hour after your breakfast, then test hourly until your lunch.
• After lunch, wait an hour, then test hourly until your next meal and so on until you reach a maximum of 10 tests.

Methane producers are common but the amount you produce varies from one person to another. About 60% of us have the gut microbes required to produce methane, however, the amount you produce will depend on many factors such as diet, age or medication use. Production of methane and other gases fluctuates daily – by using AIRE 2 and tracking your diet and other lifestyle factors in the app, it enables you to see how these gases affect you and your gut health.

Visceral hypersensitivity (sensitivity to distension of the GI tract) and altered motility (constipation or diarrhea) are characteristics of IBS. About 40% of those with IBS tend to have more diarrhea. About one third of those with IBS are generally more constipated. The remainder switch between constipation and diarrhea. Those with IBS-C tend to have more methane producing microbes than those with IBS-D. Measuring both gases can help you gain clarity around your symptoms, in particular constipation.

It is important to speak with your doctor if you suspect you have SIBO. If you’ve received a diagnosis of SIBO from a doctor, this device could be helpful for tracking the levels of fermentation in your small intestine.

We have microbes living in every part of our body. This is totally normal and healthy. As we move through the digestive tract, the number of microbes at each site increases. We have the most microbes in our large intestine. However, sometimes excess microbes can end up in our small intestine. When this happens, a condition called small intestinal bacterial overgrowth (SIBO) can occur. Those with SIBO often have symptoms of abdominal pain, bloating, nausea, belching, diarrhea and constipation. Some people with SIBO may produce more hydrogen, while others may produce more methane. It is important to speak with your doctor if you suspect you have SIBO. If you’ve received a diagnosis of SIBO from a doctor, this device could be helpful for tracking the levels of fermentation in your small intestine.

Many of us are constipated regularly. Methane has been shown to slow down the passage of food in the gut and is commonly linked to constipation. Measuring methane can help you understand whether methane is factor in your constipation. Understanding the cause of your constipation may help you treat it more effectively.
