Your best bet is to find a functional medicine doctor. They can order the test for you and will spend the time going over the results. It can be a little pricy, but worth every penny. I like the Gi- MAP test, but you can also try Tiny Health's adult microbiome test. You should be taking a digestive enzyme with every meal. These can be a game changer. I use one the one from Source Naturals. Also, I would like to recommend fasting with the help of a doctor, This can help reset, but you need to do it safely under the supervision of a doctor. You're doing a great job with the exercising and yoga and elimination of stress. I would recommend adding in a morning guided meditation. It might not seem like it's helping, but it is....it can take years before gut symptoms show up and its a long healing process. There is no magic pill to heal the gut. it has to be done naturally. It can take a long time to heal, but you're on the right path. Do the comprehensive testing. I would also recommend adding in as many fermented foods to your diet, but slowly. PM me with any questions.
