Is my Kidney allright ?

[IkangSan]

Hey Guys , how are u ? Hope everyone had a good day .

I have some questions about my blood test (especially about the kidney function)

So i did a blood work , and these result got my attention :

- Fasting Blood Glucose : 88 mg/dl (normal value < 100mg/dl )

- HbA1C : 22 mmol/mol (normal value < 39 mmol/mol)

--- since kidney disease is affected by blood glucose level so i posted it ---

And these are my main concern:

-Creatinine 1.27 mg/dl (normal Value < 1.20 mg/dl)

-GFR. Creatinine : 76 ml/mins/1.73m2

- Cystatine C : 0.75 unit

- GFR.CystC : 122 ml/mins/1.73m2

- Urine yellow clear , no foam, no Albumin, no blood

* I do intense workout (weight Lifting) 4x a week

* Im om high protein diet (about 0.8mg /KG BW) -> i take whey protein powder daily when my protein intake from main foods is low

* if i compare to the last year result , i see there's a mild decreasing level of GFR. creatinine = Last Year (Jan.2019) my Creatinine was 1.07 mg/dl = GFR. creatinine was 89 ml/mins/1.73m2

*my blood pressure is normal (mostly 110/70) : i dont smoke or drink alchol

My question is :

1.Should i worry about my kidney function ? I know i should worry when the GFR <60 for more than 3 months. But my concern is : if i use the value of GFR. creatnine, i see the kidney function is decreasing . But if i see the value of GFR. CystatineC , my kidney is perfectly healthy (as i read Creatnine is affected my muscle mass, so it could increase the Creatnine level, while CystatineC is not affected by muscle mass) -- so is my kidney allright ?

2.i did test on my CystatineC on 2018 and the value it was 0.8 , while now is 0.75- which it shows my kidney is healthy -- is CystatineC more accurate than Creatinine?

3. When should i worry about my kidney based on my blood result ? And any tips for me as fitness enthusiast for my kidney?

All the answer is very much appreciated !

Thank you 😊😊😊

We are not able to diagnose. Best you ask your Doctor which blood test Cystatin C or Creatinine GFR is most accurate for you, and reason one is declining and other increasing.

[HealthBuddyMelissa]

We can't give medical advice, but there are plenty of resources to help you. What does your doctor say? How old are you? Declining kidney function is normal with age. Is it possible you could cut back the fitness just a smidge, and the high protein, say for 4 weeks and then redo bloodwork to see if the numbers improve. It might be a good way to see if how you are eating and exercising are effecting your kidneys. Also do you take any medications, both prescription and OTC?

Everyone is correct, that we do not diagnose, but can speak from our own experience. HealthBuddyMelissa is right about kidney function declining with age. You really need to talk to your doctor with your questions. It could be that your workout routine and high protein diet are not the best for your kidneys.

Hey everyone

Thanks so much for the reply

Im 30 years old (165cm / 59kg)

I had talk to my docs, they told me not to be so worry about my condition unless i have GFR <60 for 3 months

But still..... Comparing the creatinine from the last year test scared the sht out of me

(My dad just passed bcs of kidney fail, i keep thingking i would be end the same as his) 😩😩

Are you taking any other weightlifting supplements? Maybe your protein shake has creatine in it. I would say to cut down on your supplements for a few months and then get your values re-checked. You can always go back on them.

We do not offer medical advice. These types of questions really must be posed to your physicians. Make a list, be specific and make sure they are thorough and explain in a way you understand. If you don't understand completely, ASK QUESTIONS. Your healthcare providers won't know you don't understand it UNLESS you tell them. Check out kidneyschool.org, kidneyfund.org, kidney.org, AAKP.com
