Im new here and I have some questions about my GFR results. My GP found I have weak kidneys on routine tests and he had me retake them 3 months later. On the follow up I had improvement at 71 GFR (June 2019). I think I remember him doing a urine test too and he said it was good (no excessive protein in urine even tho it looks a little foamy). After that i had a cancer diagnosis and I had to take several tests over the past 4 months where they also checked my eGFR and the scores were like this : first 77 a week later 66 another week 67 another week 72 then after a month 75 and then a week ago dropped to 62. All my other tests are good like the BUN and all those are normal range. I'm 40 yo caucasian man and a little muscular, my job is a little physical and I try to go to gym 2-3 times a week. My unerstanding is that being more muscular like African American it adds 12 points to my GFR so for me I can add at least 6-10 points I would imagine. Also I am a little overweight 225lb 6.1ft tall. I have good blood pressue but high (bad) cholesterol. I work nights so i used to drink 2 Liters of coffee a day and 3-4 beers and also drink lots of water and eat protein rich foods like peanuts and peanut butter. I forgot to add that they also found a small 1cm simple kidney cyst (benign) on CT scan. What is my next step? Thank you.
