By testing the levels of methane and hydrogen through a breath test can help us determine if you have SIBO and if so, depending on whether you are hydrogen or methane dominant, the best approach to treatment.

The bonus of testing through FoodMarble is that you are also able to test your tolerance to any foods.  There are sachets that are provided in the test kit to determine if you are intolerance to certain FODMAP foods, but beyond that, you can test for any food you suspect you are intolerant to.
