My doctor started me on Trulicity about three years ago, just after I had my 3 year routine colonoscopy. I took two half doses and one full dose of Trulicity within a three week period. I wound up in the emergency room with horrible pain. I have gerd and the doctor's assistant told me to stop Trulicity immediately with a horrified look on her face. Afterwards, I have been suffering from constant pain, but my new doctor does not know what it is. I just had another colonoscopy and that's when the doctor who did the procedure found the Ischemic Colitis. Can Trulicity cause Ischemic Colitis?
