Hi. I’ve recently been diagnosed with Hypertension at age 20. While I was going to different doctors, I had quite a lot of labwork done. I’m 6’4 200lbs. I’ve always had a very lean/muscular build growing up, but i’ve recently started gaining a little bit of weight. The results of my blood work were never a concern to me until a few weeks ago when I started to look into it. My first creatinine level was 1.2, and 5 months later I had more blood work done and my creatinine was 1.32, The second creatinine level was most likely affected by dehydration, NSAID use the day of the draw, and the fact I had been started on lisinipril/hctz prior to that. So i’m guessing my baseline is about 1.2. My egfr was 77. My question is, is this indicative of kidney problems? None of the nurse practitioners mentioned my creatinine level to me. I assume the high levels are from lean muscle and a high intake of protein? I eat like a horse, but i’m not like super muscular.. Just kind of lean. I worked out a TON in highschool, but not so much since I graduated 2 years ago. I’m really worried about this, because I plan to start back at the gym soon, and I don’t want that to affect my creatinine? I guess i’m more worried about when I get older and start working out more, because my creatinine will only go up from here, and this will just cause my gfr to fall as I get older. I guess as I get older, say into my 40’s and 50’s I will lose muscle mass and gain more fat, so that would drop my creatinine and raise my GFR? is that right? ANY ADVICE IS APPRECIATED. I’ve been so worried about this that i’m not sleeping or eating. I also had a urinalysis the day of the blood draw that I was dehydrated, and it had some protein in it. I got a repeat the next week and it was clean. Thank you so much for any replies.
