Osteoporosis (Print Version)

Osteoporosis makes your bones weak and more likely to break. Anyone can develop osteoporosis, but it is common in older women. As many as half of all women and a quarter of men older than 50 will break a bone due to osteoporosis.

Risk factors include

Getting older
Being small and thin
Having a family history of osteoporosis
Taking certain medicines
Being a white or Asian woman
Having osteopenia, which is low bone mass

Osteoporosis is a silent disease. You might not know you have it until you break a bone. A bone mineral density test is the best way to check your bone health. To keep bones strong, eat a diet rich in calcium and vitamin D, exercise and do not smoke. If needed, medicines can also help.
