I’m not sure what DGIB is, but Yes, I did some deep diving into the brain/gut connection (of course with Mayo which has been my go -to for many years through several severe health issues with my husband and myself as well). And I did find there is definitely that connection after presenting my thoughts and information to my gastroenterologist NP. I also work with a holistic practitioner who has been talking of the great importance of the gut biome to me for years! , I was gene -tested and found that Pristiq works best for my Makeup and body type. That may be your first step. Good luck! And thank you Janelle for the information, too!
