question: Im a female, 70y/o and a type II diabetes for the past 28years. I recently had herpes zoster & was on medication. I had my blood chemistry done and the result was creatine 2.4 , urea nitrogen 69mg/dl , uric acid was normal. My glucose (fbs) that time was 189 and my bp was 140/80. Am i suffering from severe kidney disease? Am i on the late stage? Im pretty much worried.
