I have a single kidney due to renal cell cancer 13 years ago. I have just been diagnosed with T2D, based on a fasting blood glucose of 131 and an A1c of 6.5. So far, I am on no meds, but I've lost 20 pounds in 2 months, and still working on it. I am keeping my morning FBG between 96 and 109. I am terrified of kidney damage, and would like to hear what you think my chances are of that developing.
It’s certainly understandable that you’d like to do everything you can to prevent diabetic kidney disease. While there are no guarantees that you’ll never have kidney disease, there’s much that you can do to lower your risk. First, achieve and maintain good blood glucose control. This means keeping your blood glucose levels and your A1C level within your target range. For most people the target blood glucose range is 70-13 mg/dl before meals, less than 180 mg/dl two hours after meals, and 90-150 mg/dl before bed. The A1C goal for most people is less than 7%. Second, aim to control your blood pressure. The blood pressure goal for most people with diabetes is less than 140/90. Talk with your provider about your own goals. If you currently have high blood pressure, ask your provider about blood pressure medicines that may also help to lower the risk of developing kidney disease. Finally, keep all of your medical appointments and make sure that your kidney function is checked at least once a year (kidney function tests usually include a urine test for microalbumin, a blood test for serum creatinine, and a calculation that your provider can do called the estimated GFR). Know your “numbers” and stay on top of them. If they’re not within your target, be assertive and work with your healthcare team to find out what you can do to get them and keep them at target.
