What is Osteoporosis?

Osteoporosis is a disease that causes bones to become weak and brittle and increases the risk of fracture1.Bone is tissue made mostly of collagen, a protein that provides a soft framework, and calcium phosphate, a mineral that adds strength and hardens this framework. This combination of collagen and calcium makes bones both flexible and strong, which in turn helps bones to withstand stress2. In osteoporosis the bones lose density or mass and the structure of bone tissue becomes abnormal. As bones become less dense, they also become weaker and more likely to break3.

Osteoporosis is a silent disease – people who have it may not know that they do until they break a bone4. Osteoporosis can develop on its own or as the result of: having another disease (like anorexia, cancer, diabetes, rheumatoid arthritis, thyroid disease, kidney failure, liver disease), the use of certain prescription drugs (corticosteroids, phenytoin, barbiturates, heparin), alcohol and tobacco use, and being unable to move for a long period of time due to a medical condition or injury5.

Osteoporosis affects men and women of all races, but is twice as common in women as men1, 6. Treatment for osteoporosis includes medication and hormone-related therapy1. Lifestyle changes and changes to medications (if possible) may reduce the risk of fractures1, 2.

How Common is Osteoporosis?

Osteoporosis is the most common bone disease6. About 40 million Americans have osteoporosis or are at high risk to develop osteoporosis due to low bone mass7. Studies suggest that approximately 1 in 2 women and up to 1 in 4 men age 50 and older will break a bone due to osteoporosis8.
