Gas, Anal Bleeding, Diabetes, Pancreatitis

I'm not sure what to expect from this forum but here goes. My mother has been having health problems ever since her hysterectomy. She has been diagnosed with diabetes type i, pancreatitus, ibs and most recently she has acquired painful arthritus. She has undergone 3 colonoscopies, 2 catscans and even an mri. So far, the health care providers in ontario have removed a perfectly healthy gall bladder and reopened a bioduct. She has abdominal pain most days, and has chronic gas. She also has profuse anal bleeding (we're talking bowlfuls) that they haven't been able to diagnose. Everytime she has a "pancreatitus" episode they put her on a iv, give her pain killers and send her home again after a few days. Last week, her anal bleeding and ab pain were very bad and she was very pale. When she went to the hospital her white blood cells were critically low so that she required a transfusion. No one can tell her what exactly is wrong and how to treat "it". She takes painkillers for the arthritus, hormone replacement therapy pills, beta blockers for an irregular heartbeat, insulin shots for diabetes, and I worry that the meds are causing some of these problems. Any insight or advice would be greatly appreciated.
