I am on peritoneal dialysis and sometimes the effluent smells funny, why is this?

See below. It is after all bodily fluid. Have it examined by your nurse or doctor if it is cloudy it is possibly an infection.
Peritoneal Dialysis. I've been thinking about your question for some time. The only thing i can think of is that this is either due to something you've eaten. Abnormal odor of the dialysate can mean infection, but there should be cloudy fluid and/or blood in the effluent. I would recommend talking with your doctor about getting a culture of your dialysate along with a cell count and microscopic exam of the fluid.
