You may have heard about breath testing before, but many people don’t know that breath testing is a non-invasive way to get a more complete picture of your gut health. Breath testing measures certain gases produced in the gut microbiome that - when abnormal - can indicate specific gastrointestinal conditions like small intestinal bacterial overgrowth (SIBO), intestinal methanogenic overgrowth (IMO), and/or excess hydrogen sulfide.

What Is the Gut Microbiome, and Why Is It Important to Your Overall Gut Health?

The human microbiome is described as a group of microorganisms such as fungi, bacteria, and viruses that live in certain areas of the body. In this case, the “gut microbiome” refers to those microorganisms that live in the digestive tract to help you digest food. Aside from aiding in digestion, the gut microbiome impacts the immune system and brain health. Good gut health starts with a healthy gut microbiome.

How Can Breath Testing Contribute to Your Gut Health?

Breath testing is a clinical way to analyze certain gases detectable in exhaled breath that can indicate common gastrointestinal disorders that affect your gut health like SIBO, IMO, and excess hydrogen sulfide. There are three primary fermented gases detectable with a breath test: hydrogen, methane, and hydrogen sulfide. Each gas is associated with a different gastrointestinal condition.

  • Abnormal hydrogen is indicative of SIBO.

  • Abnormal methane is indicative of IMO.

  • Abnormal hydrogen sulfide is indicative of excess hydrogen sulfide.

Is Breath Testing Right for You?

A breath test could be considered if your gut health is disrupted with the following symptoms, once a week or more, for at least four weeks.

  • Bloating (especially after eating)

  • Gas

  • Abdominal pain

  • Constipation

  • Diarrhea

Understanding your gut health by way of a breath test is not just another wellness trend. A breath test can help your provider personalize a treatment plan for you allowing you to feel better quickly.
