Research shows that after age 40, kidney function can naturally decrease by about 1% per year. So, is it normal for GFR to go down as you age? This is a crucial question for anyone over 60, and the answer requires understanding the subtle differences between normal aging and disease.
Studies indicate that for healthy individuals, a gradual and natural decline in kidney function begins after the age of 30 or 40. Understanding **how much eGFR goes down with age** is essential for interpreting lab results and maintaining optimal senior health.
According to numerous studies spanning decades, GFR (glomerular filtration rate) is known to naturally decline with age. This decrease is considered a normal physiological process and typically begins after the age of 30 or 40. Understanding if it is normal for GFR to decrease with age is key to properly interpreting lab results and differentiating between normal aging and signs of chronic kidney disease (CKD).
After age 40, the glomerular filtration rate (GFR) typically begins a gradual, physiological decline, which is a normal part of the aging process. This expected change often leads many seniors to ask, **does your GFR go down as you get older**, and what does it mean for overall health?
