Devin @djfilipiak your case sounds complicated to say the least! I have a history of gastroparesis due to autonomic neuropathy complications of diabetes and I have also been diagnosed with diverticulosis/ diverticulitis that seems to be genetic. Both my dad and grandfather had it. From a dietary standpoint the two conditions respond best to different & opposite things. Gastroparesis does well with small, frequent, low fiber snack like meals. Diverticulosis/ diverticulitis does better with high fiber. So the balancing act can become frustrating. But my situation has never involved surgery and for that I am thankful. It sounds as though you have endured several unsuccessful surgeries. It is very disappointing that Mayo “denied your case”. I think the world of them and thought they would be the ones to help if no one else could. I’ve always had the impression that Mayo enjoys a challenge and I would be inclined to keep asking if I were you. However I’ve personally experienced that they don’t like to be the ones to have to fix others’ mistakes so maybe there’s that. Whatever you do I would look to a large teaching facility for your care and further treatment.
