Should I visit a doctor for my slightly low eGFR?

Question

Hi doctor,

I do not have any real complaints. I just got my laboratory test results. They show BUN (blood urea nitrogen) 29.1 mg/dl, creatinine 1.01, BUN/creatinine ratio 29 and eGFR 64. I do not have any bad symptoms other than some retention of fluid. I urinate a lot but I am on Triamterene 75/50 twice a day. I do drink lots of water and tea without sugar. I have heart disease and had bypass before 10 years. My general physician said that everything is fine because creatinine was fine. I am still concerned after things I have read. Should I seek a visit with specialist?

Hi,

Welcome to icliniq.com.

I would like to know your age and how your heart functions. Do you have any recent 2D (two dimension) echo done?

Regarding serum creatinine and BUN (blood urea nitrogen), they are normal. But, eGFR - estimated glomerular filtration rate is slightly low. That really need not worry.

After the age of 40 years, eGFR starts dropping every year and it is normal. Aging process is similar to graying of hair.

Just do a 24 hour urine protein estimation and a 2D echo if not done recently. Let me know your age and reports as advised. Thank you.

Hi,

Your eGFR is low only because of your age. It is not due to any pathological process.

Keep checking your creatinine yearly. Keep in mind the rate of decline of eGFR, which is more important than actual eGFR in your case. Take care.
