Osteoporosis is a disease marked by decreasing bone mass and density, making bones weak and brittle. If left unchecked, it can lead to fracture. Any bone can be affected. Fractures of special concern are of the hip, spine, and wrist.

Osteoporosis is caused by an imbalance between bone loss and bone formation (known as bone remodeling). After age 30, bone loss occurs more quickly. Many factors over the course of a lifetime can influence bone remodeling.
