Measure Density of Bone To Prevent Osteoporosis

The density of bone can be measured by a bone mineral density (BMD) test using a special X-ray or computed tomography (CT) scan. The test is conducted to estimate the strength of your bones.

With age, bones become thinner because the existing bone is broken down faster than new bone is made.  Bones lose calcium and other minerals and become lighter, less dense, and porous. This makes the bones weaker and increases the chance of breakage. As the density of bones reduces, it often leads to osteoporosis.  Osteoporosis is more common in women above 65 years of age.

Densitometry or DXA scan determines whether you have osteoporosis or if you are at risk of osteoporosis. It can make your bones more fragile and can increase the chance of breakage.

A bone density test uses X-rays to determine how many grams of calcium and other bone minerals are packed into a segment of bone.

A bone density test is conducted to:

  • Evaluate bone density before you break a bone
  • Determine your risk of fracture
  • Confirm a diagnosis of osteoporosis if you have experienced broken bones
  • Monitor osteoporosis treatment
If the density of your bones is below normal, you need to take steps to increase your bone strength and reduce your chances of having a fracture. Proper diet and regular exercise can help you increase your bone density and strength. You can also combine calcium and vitamin D supplements with weight-bearing exercises such as walking, weight training.

It is the bone mineral content that decides the strength of your bones. The higher your bone mineral content, the denser your bones are. And the denser your bones are, less likely they are to break.
