I have suffered with bowel urgency and diarrhea for years. I’m 62. Seems to have started when gallbladder was removed several years ago. That said, I’ve suffered with GI issues for decades. Just had my first consultation with GI doctor at Mayo Clinic Scottsdale. Awaiting a whole raft of tests, including colonoscopy with biopsies, CT scan, breath and blood tests, stool tests, the list goes on. Advised to remove sugar and non caloric sweeteners from my diet, to take immodium 20 mins before meals and then as needed, and cut way back on fruits and vegetables. I have been loosely following the FODMAP elimination plan in the Mayo Clinic GI book and finding benefit even doing it imperfectly. Not happy that I can’t eat the fruit I love (mango is my favorite) or drink juice, but I guess if I was told to eat nothing but spinach (yuk!) I’d do it to be rid of this affliction. Good luck. Keep us posted how you’re doing.
