I am a 22 year old male with a creatinine of 1.7 (March) on my last blood test. 1.54 (February) and 1.4 (September) prior from 3 different labs. Last GFR was 51 from the 1.7 creatinine level. I am 5'8" 174 pounds and I am a bodybuilder. High protein diet, used to use heavy supplementation (protein, creatine, bcaas), and worked out twice a day. Last BP readings of 102/60, 102/66, 105/62, 111,70 and yesterday was 110/70. Heart rate around 48-55 bpm. No diabetes or hypertension. No blood or protein in urine after two dipstick tests. I had an Ultrasound that was taken and came back normal I had a 10.9 right kidney and a 10.7 left kidney.
I am now instructed to do a 24 hour urine test and a follow-up blood test day of urine return. Saw my doctor yesterday and he is not worried at all and said he is optimistic it is not CKD.
My protein in the urinalysis was 4.0<mg/dl (normal is 5.0 - 24.0 mg/dL) and my creatinine was 110.mg/dl (normally 20.00 - 370.00 mg/dL). Both very much within normal range but I also cut out meat since hearing this so that probably why my protein is low on this urinalysis. I did not fast and ate two high protein meals before the 1.7 creatinie blood test that was a week back and was on accutane. I had not fasted for any of the blood tests.
I am not convinced, I am very worried from everything I've seen and read. It seems like my gfr has decreased from 73-63-51 over last 6 months. Pain in front/side mostly on left but seems to move to groin and switch sides. Unsure if its kidneys or anxiety induced. It started the day I found out about the 1.7 result but has not gone away. It does come and go. No real back pain. Sometimes I see foamy urine but it mostly dissipates within a minutes time. Sometimes foam stays. I am very worried and scared. I am extremely healthy so i do not understand what is going on. Any opinions, advice, experience would be much appreciated.
Thank you so much for your time,
Andrew
