Bone Density Test


A bone density test, or densitometry, is a scan that measures bone density. It is also called a dual energy x-ray absorptiometry (DXA) scan. The test uses x-rays to show if your bones have lost minerals, such as calcium. The loss can cause your bones to become weak. A loss of density may increase your risk for osteoporosis. A bone density test is usually done on your hip, spine, or forearm. It can also be done of your entire body.


Seek care immediately if:

  • You fall and think you may have broken a bone.
  • Your condition or symptoms suddenly get worse.

Call your doctor or orthopedist if:

  • You have questions or concerns about your condition or care.

Protect your bones to help prevent osteoporosis:

  • Eat foods that are high in calcium and vitamin D. Calcium and vitamin D work together to strengthen bones. Examples are milk, cheese, yogurt, salmon, tofu, almonds, and beans. Limit caffeine. Ask your healthcare provider if you need a calcium or vitamin D supplement.

    Sources of Vitamin D
  • Exercise for at least 30 minutes, 3 times a week. Do weight-bearing exercises, such as walking. Exercise can help increase your bone density and decrease your risk for fractures. Ask your healthcare provider about the best exercise plan for you.
  • Prevent falls. Keep your home well lighted so you can see things clearly. Remove throw rugs, or secure them to the floor. Install grab bars near your bathtub and toilet. Ask your healthcare provider for more information about preventing falls in your home.

  • Limit alcohol. Women should limit alcohol to 1 drink a day. Men should limit alcohol to 2 drinks a day. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
  • Do not smoke. Smoking can decrease your bone density, and increase your risk for a broken bone. Nicotine and other chemicals in cigarettes and cigars can also cause lung damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products. Ask your healthcare provider for information if you need help quitting.
