For some reason this year I went home and looked up GFR. When I began to realize the significance of declining kidney function, I went back and asked what I could do to slow or stop the decline. Was told it's not low enough to worry about. I asked if he normally sees otherwise healthy people with low GFR. He said no, it's usually seen in patients with diabetes or high blood pressure. I asked about a urine test to check for kidney damage. He agreed and was told it came back normal (although I never saw the results). I asked what else we could do.
He said we could try a very low dose of ACE inhibitor as my blood pressure is occasionally slightly elevated. I agreed to try this. I have since asked for a referral to a specialist and was told my GFR "isn't really that low."
I've read that diet may help slow down kidney decline and spoke to an acquaintance, who is a dietitian, about it. He thought I should see a kidney specialist to determine if there is a specific problem and is reluctant to give me advice about diet without knowing more about what is causing the decline.
I'm feeling frustrated right now and don't know if I'm over reacting or if I should make an appointment myself with a specialist. Would probably have to pay out of pocket without a referral from my family doctor.
