Hi,
I'm 35 going on 72! Well at least I think I'm 35, my fitness and strength are above average for my age. I don't exercise anymore and rely on being mobile as much as possible pottering around in my workshop. I climb stairs several times a day which they say is far more exercise than walking, so maybe that is what helps me. Unfortunately I seem to have everything you don't have. I switched to a kidney friendly diet which coinsidentaly dropped my cholesterol from 9.8 to 6.8 and still has my Dr panicing.
I always thought I was doing well until I discovered my mother-in-law at 95 with a GFR 18 and absolutly no medical or dietry help still functions well for her age, although she only walks short distances with a walking frame. She eats what she likes regardless of any advice from her Dr or us!
I discovered I could push my GFR higher with strict diet for kidneys, but it is very strict, forgoing food and medicine that could affect the kidneys and ignoring my other health issues. I managed to push the GFR up to 58 but didn't enjoy the lifestyle. I now have little control of what I can eat as with the digestive problems I now have just eating is an accomplishment. But am still mindful of the kidney requirements.
My kidneys are the least of my concerns now with GFR38 they will last me out, as long as I'm not stupid.
With the Dysautonomia affecting a lot of my bodily functions, there is little that can be done. I now focus on quality rather than quantity of life.
Cheers
