I have had diarrhea for about a year (10-14 times/day), along with tiredness, lack of energy, hot flashes, weight loss. I've had CAT scan with contrast from my neck to my pelvis, and a bone scan of my entire body, ordered by my oncologist. I've had a colonoscopy to rule out Crohn's disease and any colitis. Everything is negative. I'm taking EnteraGam and Cholestyramine each once/day. I still have the symptoms. Doctors want to treat the symptoms, but not find the cause. What is wrong with me? I had breast cancer 35 years ago and gall bladder removal 2 years ago.
