Kidney function declines naturally with age, even if a person is in good health, a new European study says.
Researchers assessed nearly 3,000 people in Norway, Germany and Iceland, age 50 and older, in order to learn more about how kidney function changes with age.
“What happens in our kidneys when we age is representative of all the other things that happen in our bodies. The kidney function deteriorates, not because we get ill, but as part of aging,” said lead author Bjørn Odvar Eriksen, leader of the Metabolic and Renal Research Group at the University of Tromsø (UiT)–The Arctic University of Norway.
Because loss of kidney function happens to everyone, Eriksen said it is an ideal way to determine aging in general.
