I agree, unfortunately I also have the Barrett's as well, it seems it all comes together as a bargain offer!
One thing I have picked up from this forum is not to accept a prescription for Metformin under any circumstances, I know we are all different but I had an internal haemorage a couple of years ago, it took three months to get a colonoscopy by which time the radiographer told me as I had no further trouble it was probably a waste of time as they would not find anything unless it was very serious, happily they didnt.
My consultant has told me not to eat anything that would upset the diverticulitis and risk another haemorage as they don't know what caused the last one, I also have to keep a supply of antibiotics with me although so far touch wood I haven't needed them, what ever happens I must beat this with diet.
Basically like all of us diabetes I need like a hole in the head!
