At what age does bone loss typically begin in older adults?

Bone loss typically begins around the age of 40 in older adults. This age is significant because it marks the onset of a gradual reduction in bone density, which can continue into advanced age. Factors contributing to this process include hormonal changes, particularly in women during menopause, as estrogen plays a crucial role in maintaining bone density. With aging, the rate of bone resorption (the process where bone is broken down) begins to exceed the rate of bone formation, leading to a decrease in bone mass. Recognizing this early onset of bone loss is vital for implementing preventative measures such as dietary changes, exercise, and medications when necessary. These interventions can help mitigate the impact of bone loss and prevent related conditions such as osteoporosis later in life.
