Re: worried about creatinine increase
Try to relax a bit. A jump from 1.6 to 2.0 is not a big deal. I wouldn't read too much into the stages either. I didn't go on dialysis until my creatinine was about 10 or 11. Kidney readings fluctuate quite easily. You could have been a bit dehydrated, or you could have been getting a bit more exercise (muscle mass and exercise will raise your cr.). It's trends over time (months and years) that you want to watch out for. I don't think I buy the "stage 4" either. What would I have been at 10? Stage 20?
Ask to have the lab repeated and make sure you drink enough before hand. It might be a real increase, or just a fluctuation. And you are still in very early stages of kidney issues.
