How To Cure Diarrhea After Kidney Transplantation?

I Have had a diarea problem for several weeks. I Have had my stools checked and nothing was found . I first went into the er and was dehydrated. I thought I just had what was going around. they did find a urinary infection. the dr, put me on anantibotic and did a clean ketch.told me to rest my stomach and to stop taking my probiotic and my Metamucil. I am a kidney transplant patient. a week later my dr told me to take them that I souldnt have stopped he was upset that the er dr told me to quit them. my dr told me to eat yogart and lots of cheese. I did not have cydisc. later my dr. sent me to my gastro. dr. every thing checked out fine. I don t have watery stools but I still have trouble with diarea.I have no energy. my kidneys bun is 38 and my creatine is3.1. I had a colonoscopy about a year ago. My daughter thinks it has something to do with my chickens.SandySue
