Im 73 with heart disease and ckd with a egfr of 30. Three years ago it was 80 and dipped to 60 for no apparent reason. I am mostly retired and want to travel and enjoy my final years. watching diet and controlling weight. Work out 2 days/week at a fitness place and walk 3 days/week. Drinking tons of water and liquids, cut back on protein, especially red meat. Feel great...hoping for the best. Im totally not impressed with the nephrologists, they dont have any real magic patients! Keep the faith, do all you can to stay as healthy as you can!
