Bone mass generally peaks around the age of 30-35, and then starts to slowly decline at around age 50 in women (60 in men) when you start to lose bone mass faster than your body can grow it back. This happens to all adults, however critical loss of bone mass (osteoporosis) is much more common in women.
Causes of osteoporosis. Osteoporosis causes bones to become less dense and more fragile. Some people are more at risk than others. Bones are at their thickest and strongest in your early adult life and their density increases until your late 20s. But you gradually start losing bone density from around the age of 35.omen. Women are more at risk of developing osteoporosis than men because the hormone changes that occur in the menopause directly affect bone density. The female hormone oestrogen is essential for healthy bones. After the menopause (when monthly periods stop), oestrogen levels fall.
