As the bones get thinner, they become weaker. There is a much greater risk they will break if you fall or have an otherwise minor injury. Medical complications of these injuries can result in longer stays at the hospital, disability, and even death. Osteoporosis is most common in white and Asian women, especially slender women. Osteoporosis occurs as women get older.
Sex hormones help keep bones strong.
The hormone estrogen helps women's bones stay strong. For example, it helps deposit calcium in the bones. Women produce much less estrogen after menopause. The lower levels of estrogen cause a weakening of the bones. Women who smoke or are physically inactive are at a greater risk of developing osteoporosis.
