Gut Microbiome Tests: What They Do (& Don't) Tell You

On Health with Houston Methodist

What if there were tests that could determine which foods to add or subtract from your diet for optimal health? That’s just one of many overarching claims of the various gut microbiome tests now available and gaining popularity online. But can an over-the-counter test really tell you how healthy (or unhealthy) your gut microbiome is? A gastroenterologist breaks down what you should know about these expensive consumer health tests.
Expert: Dr. Christopher Fan, gastroenterologist
Notable topics:

• The differences between tests gastroenterologists use and at-home tests
• Is there a true definition of a healthy gut microbiome?
• Do we actually know which microbes are “good" or “bad?”
• Can you address constipation, bloating and other symptoms through these tests?
• Leaky gut: The truth about this term making the rounds online
• Who (if anyone) might benefit from gut microbiome testing
• Actions you can take to promote a healthy, happy gut microbiome
