I have it all the time and they say its Irritable Bowel Syndrome with chronic diarrhea. Sometimes it is very bad and extremely painful. My gi doc is ok and does colonoscopy and endoscopies on me. I did have a colon polyp once that was cancerous and often have irritated patches that bleed in my colon and duodenum and they biopsy them and there is no cause so they assume autoimmune, though I don't test positive for anti smooth muscle antibodies or whatever the antibody is for it so I'm not sure they are right. You might switch to drinking bottled water, steam distilled is the best since some spring water is really just drinking water from another part of the country and more expensive. I'm learning that levels that are considered safe for many people of certain chemicals in city or well water are not often safe for people with illnesses, and I didn't know that the water treatment places and testing places let it go that high.
My mother and I had a really bad bout of something very bad once and it lasted like two months and it was horrible. Finally a medicine called flagyl cleared it up but it took like two doses.
Is your food digested? If not, mine isn't usually, I eat and then out it comes, and the gi doc told me that that's a sign of small intestine problem vs colon problem.
Sometimes medication allergies come like this, and then after a month or so of diarrhea you get a rash, I've had that happen. Food allergies can do this too. I imagine they put you on a bland diet to try to rule that out.
You might have them check your liver function in bloodwork if they haven't. I've been living with this kind of thing off and on for years now and I hope that you don't have to because its ruined my colon and there's no excuse except the docs don't know how to diagnose or won't run the right tests to diagnose anymore.
Glucophage can be really irritating and cause diarrhea in most people if you have any tendency toward irritable bowel or bowel problems too.
I would try to get the scope done, like colonoscopy/endoscopy if they will do it because even though they have to put you out, you probably can't keep the barium in anyway due to the diarrhea, and with the scope they can diagnose a lot more and they can do many things while they are in there to fix problems, see irritated patches they can see with barium xray, take biopsies and remove polyps and you are knocked out when they do it.
Well, I hope your doc gets on the stick and does something. My doc has his own endoscopy center right there in the office so if theres any question, he just goes in and looks. I know other people have to have it done at the hospital. I hope you feel better soon.
