Osteoporosis occurs when bones become 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.

Throughout life, old bone is removed and new bone is added to your skeleton. After age 30, more bone is lost than replaced. If too much bone loss occurs, this may lead to osteoporosis. Osteoporosis is more likely to occur if full bone mass was not achieved during your bone-building years.
