Hi, my father 74 years old’s Kidney function has suddenly started fluctuating. In June 22 , EGFR was 56, in September we noted 22. In Oct “19”, in Oct after 2 weeks of first test “34”. Since then every 2 weeks we noted it goes around 50 and then down around 15. There are no symptoms of kidney failure , no or minor protein in urine. No swelling. He is blood pressure and heart patient but all well controlled. Very well diet control too. Doctor has not advised Dilysis yet. Any suggestions?
