Is Osteoporosis Genetic?

Osteoporosis, sometimes called porous bone disease, is a condition in which bones lose density and are prone to fractures. The bones of the hip, wrist and spine are the most frequently affected.

Significance

• Millions of Americans have osteoporosis, and millions more have low-density bones that put them at risk for developing the disease. Most people with osteoporosis are post-menopausal women, but men and younger people are also at risk.

Considerations

• Many factors, from diet to exercise habits, affect your chances of developing osteoporosis. Genetic factors definitely do play a role, though. At the same time, having a genetic tendency does not mean you will get osteoporosis.

Expert Insight

• In a study conducted at Edinburgh University's Molecular Medicine Center, researchers found that heredity is a contributing factor in whether or not you develop osteoporosis. The scientists concluded, though, that "environmental factors" also have a strong influence.

Environmental Factors

• If there is a history of osteoporosis in your family, you can counteract this genetic tendency by changing environmental factors over which you have control. For example, choosing a diet rich in calcium and vitamin D, getting plenty of exercise and not smoking are things you can do everyday to reduce your odds of getting osteoporosis.
