Weight-bearing exercises, started in your youth and
continued throughout your life, can help prevent
osteoporosis. These exercises, such as walking,
jogging, climbing, dancing, or lifting weights, help you build strong bones as
a young person. And they help you maintain your bone thickness (density) as an
adult. But if you stop exercising, your bones will begin to thin.
these exercises at any age will help prevent bone loss. It is best to do
weight-bearing exercise for at least 2½ hours a week. One way to do this is to
be active 30 minutes a day, at least 5 days a week. In addition to
weight-bearing exercise, experts recommend that you do resistance exercises at
least 2 days a week.
A bone density scan can detect thinning bones at an early stage. If you already have osteoporosis, bone scans can also tell you how fast the disease is progressing.
But an abnormal bone scan can create as many questions as it answers. Who should get a bone density scan, and what do the results mean? If your bone density is below normal, what can you expect, and what should you do?
