What Is Osteoporosis?
A bone mineral denisity (BMD) test is used in screening for osteoporosis to test the strength and solidness of the bones.
Osteoporosis (or porous bone) is a bone disease in which bones become weak and are more likely to break.
Without prevention or treatment, osteoporosis can progress without pain or symptoms until a bone breaks (fractures).
- Fractures commonly occur in the hip, spine, and wrist.
- Osteoporosis is often the underlying cause of bone fractures.
Osteoporosis is not just an "old woman's disease." Although it is more common in white or Asian women older than 50 years of age, osteoporosis can occur in almost any person at any age. In fact, more than 2 million American men have osteoporosis, and in women, bone loss can begin as early as 25 years of age.

Building strong bones and reaching peak bone density (maximum strength and solidness), especially before the age of 30, can be the best defense against developing osteoporosis. Also, a healthy lifestyle can keep bones strong, especially for people older than 30 years of age.

Osteoporosis is more or less preventable for most people. Prevention is very important because, while treatments for osteoporosis are in place, currently no cure exists. Prevention of osteoporosis involves several aspects, including nutrition, exercise, lifestyle, and, most importantly, early screening with bone density tests.
The Importance of Screening for Osteoporosis
Early detection of low bone mass (osteopenia) or osteoporosis is the most important step for prevention and treatment. If osteopenia or osteoporosis has occurred, a person can take action to stop the progression of bone loss.
Remember, effective treatment or prevention cannot take place if a person does not know he or she has, or is at risk for, osteoporosis.
