Urology/37 yr old husband has low eGFR



I just wanted to ask some thoughts about what is going on with my husband.

My husband gets regular bloodwork every 6 months for a pituitary tumor so a couple months ago we started searching what his eGFR means (we never really searched it before and it was never brought to our attention by his endocrinologist)

We went back a few years and it's been ranging between 72-78 (up and down).

In our searches we read it should be over 100 or at least over 90 right now and that it will decline 1 point a year and now we are very worried about what will happen as he gets older. We are worried when he is in his 50s his eGFR will be in the 60s, then when he is in his 60s it will be even worse and so on.

Is it definite that his eGFR will lower like this (1 point a year) and he will be diagnosed with state 3 or even 4 later in life?

We are extremely worried as he has been through so much already.

Thank you in advance.


GFR is a measurement of the capacity of the kidneys.  It tends to slowly go down as we get older.  The "e" means "estimated" so it's not absolute.  

As long as his physician is checking it, that is usually sufficient.

It is not certain that the GFR will necessarily lower and result in renal failure later.

In younger men, this is often misleading as the estimates are just that; estimates.

This is a question that should be directed to a nephrologist as it really is in their area of specialty.
