My creatinine is 105 gfr is 82 i dont have diabetes or high bp.how can i improve kidney function.should i be worried?

How do you FEEL?: If you're a reasonably well-muscled young man, that creatinine is normal. The GFR's estimates are subscientific; I believe they've been added to make people think they need to take unnecessar medicines. There's even a racial adjustment "because black people are more muscular." When I was lifting weights daily, I was suddenly a kidney case. I'm not and I bet you are not either.
