At-home gut tests are becoming popular with people who want to learn about their stomach health. These tests are sold online and ask users to send a stool sample to a lab. The company then sends a report that shows the types of bacteria found inside the body. Many people feel curious and hope the test will help them feel better or stay healthy. Doctors say the tests are not made to find disease and should not replace medical care.

Experts explain that gut bacteria are very different for each person and can change often. Because of this, doctors cannot always give clear advice from the results. Some tests also suggest vitamins, but doctors say a balanced diet, good sleep, and exercise are more helpful. Eating vegetables and whole foods can help keep the gut healthy. Doctors say people should see a clinic if stomach pain becomes serious.
