What is osteoporosis?

Osteoporosis is a disease that thins and weakens the bones. Bones become fragile and fracture (break) easily, especially the bones in the hip, spine, and wrist. In the United States, millions of people either already have osteoporosis or are at high risk due to low bone mass. Osteoporosis is a silent disease, meaning some people don’t know they have it until a bone is broken.^[1]
