Your blood glucose is high, did your doctor diagnose you diabetic? Have you run any tests about insulin? I think you need to go back to the doctor, get the diagnosis, you may need to start on medication. If you manage your blood glucose well you kidney can be less impaired. When you said BM issue, do you mean bone marrow or BMI? If it's a BMI issue, yes, obesity isn't good for either blood sugar, blood pressure, kidney, liver, heart... So get a lifestyle change, do more physcial exercises, take low GI foods, etc.
