Age-related changes in kidney function

As people age, their kidney function naturally declines. The kidneys' ability to filter waste and excess fluids decreases, leading to a reduced glomerular filtration rate (GFR). This means the kidneys are less efficient at removing toxins from the blood. Additionally, changes in blood flow and a decrease in the number of functioning kidney cells contribute to this decline. While many older adults remain healthy, some may experience kidney-related issues, making regular check-ups important for monitoring kidney health and addressing any potential problems early on.
