I am 61 years old and suffering from diabetes since last 15 years, which has always been under control with oral medication. MY H1B AC remaining 6-6.4 always. For the last one year I am observing my creatinine level has been gradually rising from 0.9 to 1.09 and blood urea from 28 to 35. Even though all seems to be in range would like to know of preventive medicine so that create nine and urea level do not rise further. There are no proteins in urine and urine micro-albumin is 5.0. Would appreciate if you could advise.
