Do kidneys get smaller as you age? Unpacking the Science of Renal Aging

By age 70, the average person has lost a significant percentage of their nephrons, the kidney's filtering units. It is a natural part of the aging process, but the question remains: do kidneys get smaller as you age? The answer is more nuanced than a simple yes or no, involving both natural decay and compensatory mechanisms.

Does kidney size decrease with age? A look at normal aging versus disease

Studies have shown that kidney mass and function naturally decline as a person ages, particularly after the fourth or fifth decade of life. This physiological process directly contributes to answering the question: **Does kidney size decrease with age?** However, while a gradual reduction in kidney volume is common, a significant or rapid decrease can signal underlying health issues.

Does GFR go down with age? A comprehensive guide to normal kidney function decline

After age 40, the average person can expect their glomerular filtration rate (GFR) to decline by approximately 1 mL/min/1.73 m² per year. So, does GFR go down with age? The answer is a clear yes, and this physiological change is a normal part of the aging process, reflecting gradual structural changes in the kidneys.
