I Am A 59 Yr Old Female On Peritoneal Dialysis

I am a 59 yr old female on peritoneal dialysis waiting for my second kidney transplant. Since I started dialysis in July 2015 I have totally lost my appetite and have no desire for food. I've lost about 50 lbs and my nutritional values that are required by the dialysis team are very, very low....protein,potassium they are very worried about me. No one can figure out what is causing it.
