In most cases, once kidney function is lost, it cannot be recovered. This is true for chronic kidney disease (CKD) but in some cases acute kidney injury can be reversed. I suggest that you consult with your physician and follow his or her advice about controlling your diabetes and high blood pressure. These two diseases are the most common cause of CKD. The goal of treatment for CKD is to prevent and slow further decline in kidney function. Once lost, this kidney function is generally not recoverable.
