I am 73, and pretty good health. I got a report from my general practition today regarding my Creatinine, Serum level begin 1.31, above the normal range of 0.57-1.00, she referred me to a specialist for Urine. I just started drinking Black Currant Juice. Will that cause any issues with kidneys. Also, I've been on Dyazide for H/P for over 40 years. I think it is best to stop that drug. Need your advise.
