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 density

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.
