Diabetic nephropathy is kidney damage that occurs with diabetes. It is the job of the kidneys to:
Damage from diabetes can prevent the kidneys from working well. In some cases, this can lead to kidney failure.
Blood passes through small filters in the kidneys. Changes in the blood vessels due to diabetes can cause damage to these filters. Blood sugar levels that are not well-controlled can have the greatest impact on the kidney filters.
Over time, the damage to the filters increases. The damaged filters cannot clean the blood properly and protein from the blood can leak into the urine. If left untreated, this can lead to kidney failure.
Symptoms may not appear until the kidney damage is severe. Symptoms may include:
You will be asked about your symptoms and medical history. A physical exam will be done.

If the kidney failure progresses you may eventually need a kidney transplant.
