I am caring for my 91-year-old mother in my home. In October she was in the I.C.U. for a week due to internal bleeding.The doctors did not want to do a colonoscopy because of her age and because we would not choose to give her an operation if some problem were found. When she was in follow-up rehab she was diagnosed as being colonized. She came home the day before Thanksgiving. The bleeding had stopped and the infection was controlled. Yesterday she had diarrhea, in the early a.m. There was quite a bit but just once. Today she is having gray, watery stool that looks like very watered-down oatmeal. Her visiting nurse is coming this p.m. but I would like your input. Her appetite is almost non-existent, so she is living on Ensure.
