no thats not what i meant.
chances are right now you are going a bit catabolic since youve changed your diet, are a bit stressed/put out, have a painful acute condition etc etc. this will prop up your blood creatinine
value (in the lab test.
many doctors will forget about muscle breakdown as a source of elevated blood creatinine, and will attribute the high creatinine to poor kidney function alone.
so, be sure to point out to the doctor that you have lost a lot of muscle (ie keep a diary) so that he doesnt think that your kidney function is worse than it actually is.
if he does think your kidney function is worse than he really is, then he might make reccommendations which are far too conservative, and will have a severe effect on your body
i was working in a hospital checking blood values (boooooooooooring) on a placement and i noticed that all the post operative patients had high creatinine values. i was thinking, gee, whats the story with these post op pateints and shitty kidneys? i had a chat with the long time pharmacist there, and he says that its because of all the muscle loss while they arent eating normally after the operation, and not ot worry too much
id bet that a lot of doctors in the community (ie like the one you are probably seeing) probably wouldnt be as on the ball about this issue when they considered your case
also, the post above about the acidity of many BBer activities was quite good
cheers
