People on dialysis can do quite well. On the other hand, it is troublesome to do dialysis three times a week. Some patients have real problems with the dialysis treatments. We feel having normal kidneys is best of all. If you have kidney failure, a transplant is next best.
Dialysis can be fine and is better than being dead.
There is no particular problem with sweets in kidney failure. Since one-third of patients with kidney failure have diabetes, and diabetics should be careful about sweets, many patients with dialysis should be careful about sweets. The first is that there simply are not enough cadaveric kidneys to go around. Patients may need to wait years for their chance to get a cadaveric kidney transplant. Since patients with a transplant survive better than patients on dialysis, a timelier transplant actually improves survival.
