I agree with your nephrologist. The goal for blood sugars should be a fasting blood sugar of less than 120 milligrams per deciliter (mg/dl) and after eating is should be less than 180. I suggest that your blood pressure should be less than 130/80 and you should follow a low salt, diabetic diet. I am also an advocate for the DASH diet and you can review the DASH diet at: https://www.nhlbi.nih.gov/health/health-topics/topics/dash
I suggest regular exercise, maintain a healthy body weight, do not smoke and have repeat blood and urine testing at least every 6 months. In most cases, it is advisable for you to be treated with an ACE-inhibitor or ARB agent to treat your blood pressure and your kidney disease.
