Permitted diet before an H2 breath test

You ask yourself, Which foods are permitted up to which day before your planned appointment for a hydrogen breath test to clarify lactose intolerance, fructose intolerance or small intestinal malabsorption (SIBO)? Especially people who follow a vegan, vegetarian or simply healthy diet have problems here due to a lack of information.

From now on you will find the following information under "Patient information" as a guide a (growing) list of permitted foods. You can filter and print these by days before the date and/or food group.

We welcome feedback, suggestions for improvement and additions.
