In response to the person recently diagnosed with stage three ckd and has gout. I was diagnosed two years ago and was in total panic, like you I was told it's no reason to panic as long as I control my blood pressure. My doctor referred me to a nephrologist who sent me for a series of test, including an mri. They thought I had renal artery stenosis which is low blood flow to the kidneys. They found both my kidneys were unusually small. After a series of test that came out negative, the final conclusion was, don't eat red meat and keep my blood pressure controlled. Now I just get a blood test every year to make sure my gfr and creatinine didn't change. I'm 55, I work out daily, very careful with sodium intake and other than menopausel and hot flashes, I feel great!!
