How does aging affect bone density and the risk of osteoporosis in older adults?

Aging affects bone density by causing a decrease in mineral resorption, leading to a loss of bone mass and an increased risk of osteoporosis, particularly in women. Older adults experience brittle bones that are less compact, making them more susceptible to fractures and slower to heal after injuries.

As individuals age, bone density declines due to the resorption of minerals, which contributes to osteoporosis. This condition is more pronounced in women and results in bones that are brittle and less compact. Consequently, older adults are at a higher risk for fractures, and the healing process after such injuries is significantly slower due to decreased physiological exchange of minerals.
