Hi, I had gone through your query and understood your concerns. There is nothing to get alarmed because this is a natural happening in the course of diabetes progression. I am very happy you are this conscientious because having a well controlled blood sugar is very important in preventing the onset of diabetic complications. there are many new generation drugs are available to prevent microalbumin. they are telmisartan and olmesartan which are having better out comes in diabetic population. lisinopril is little old. usually not all pts having protein leak land up in kidney failure,only a minor population will have that fate. kindly mention your report in detail,as value below 20 is normal increased blood pressure also causes protein leak, consult your doc regarding change of medications Best Regards.
