What problems does diabetic kidney disease cause?

LowProtein/HighWaste: Protein loss into the urine can cause low protein levels in the blood, and lead to swelling in the feet and ankles late in the day, and around the face in the morning. High levels of waste products and potassium and low levels of calcium can cause fatigue, weakness, heart problems, bone problems, and sudden death. Dialysis is needed to correct these imbalances.

Kidney disease: High blood pressure, protein in urine, ultimately renal failure leading to dialysis and eventually death.
