Diabetic Kidney Damage May Be Reversible

Diabetes is the most common cause of kidney failure. Doctors previously thought that once diabetics leaked protein into their urine, the kidneys were damaged and could never heal. However, kidneys damaged by diabetes have healed after high blood pressure has returned to normal and after pancreatic transplants. Blood pressure medications called Ace inhibitors and angiotensin receptor blockers have also healed diabetes-damaged kidneys.

The kidney is supposed to allow urine, but not protein, to pass through its filters. Doctors used to tell diabetics that since damaged kidneys never heal, they could never take metformin, an important drug for treating diabetes. Now all diabetics should be told to get their diabetes under control by avoiding refined carbohydrates (added sugar and flour), losing weight, exercising, stopping smoking, and getting their HBA1C blood tests to normal. If their kidneys stop spilling protein, they may be able to take metformin again.
