Weak kidneys? Pay attention but don't worry excessively
Many older men have low-normal kidney function, but it doesn't need to become a serious health threat.
Chronic kidney disease means the kidneys—the body's blood-filtering urine factory—have less capacity to filter toxins from the blood and excrete them in the urine. Half of U.S. adults over 75 may have below-normal kidney function, but most of them will never get sick from it. In men whose kidney function is falling, certain steps can help to slow or prevent further losses.
