Iam 79 years old and was diagnosed with stage 3 ckd five years ago . My primary keeps tabs on my blood work and since I have stayed at the same level for five years he feels no need to see a neprologist. I take carvedilol,amlodipine and lisinopril for hypertension. Iam on no special diet except for watching my sodium.intake. I wonder if I should be doing more.
