A bone mineral density (BMD) test is the best way to measure your bone health. It compares your bone density, or mass, to that of a healthy person who is the same age and sex as you are. It can show. Whether you have osteoporosis, a disease that makes your bones weak. Your risk for breaking bones.
What is a BMD test?
A bone density test is used to measure bone mineral content and density. It may be done using X-rays, dual-energy X-ray absorptiometry (DEXA or DXA), or a special CT scan that uses computer software to determine bone density of the hip or spine.
What happens if BMD is low?
If your bone density is low compared to normal peak density, you are said to have low bone density. Having low bone density means there is a greater risk that, as time passes, you may develop bone density that is very low compared to normal, known as osteoporosis.
What does a high BMD mean?
A high bone mineral density is one where the bone mineral density (BMD) is usually greater than two standard deviations above what is expected for age. This can sometimes be seen on routine DEXA scan assessment.
What is normal BMD?
A T-score of -1.0 or above is normal bone density. Examples are 0.9, 0 and -0.9. A T-score between -1.0 and -2.5 means you have low bone density or osteopenia. Examples are T-scores of -1.1, -1.6 and -2.4.
What is normal bone density for a woman?
A T score of -1 to +1 is considered normal bone density. A T score of -1 to -2.5 indicates osteopenia (low bone density). A T score of -2.5 or lower is bone density low enough to be categorized as osteoporosis.
What are three methods of testing BMD?
Bone mineral density
- Dual energy X-ray absorptiometry. The most commonly used technique for measuring bone mineral density is dual energy X-ray absorptiometry.
- Computed tomography.
How do you do the BMD test?
During the test, you lie down on a padded platform, fully clothed. A machine arm passes above you, sending low-dose X-rays through your body. Based on how much the X-rays change after passing through your bones, it comes up with an image of your skeleton. This test lasts about 10 minutes.
What is the cost of BMD test?
A Dexa Scan is a unique type of X-ray that measures Bone Mineral Density ( BMD). Dexa Scan cost range from Rs 1500 to Rs 6000 depending on lab, location and body part.
What diseases cause low bone density?
There are many causes of osteoporosis. Not only do bones lose density with age, medications used to treat breast cancer, arthritis, asthma, Crohn’s disease and Addison’s disease can also lower bone density. Some illnesses such as hyperthyroidism, hypopituaritism and eating disorders also cause bones to lose strength.
What foods are bad for osteoporosis?
7 Foods to Avoid When You Have Osteoporosis
- Red Meat.
- Wheat Bran.
- Liver and Fish Liver Oil.
How do I know if my bone density is low?
But once your bones have been weakened by osteoporosis, you might have signs and symptoms that include:
- Back pain, caused by a fractured or collapsed vertebra.
- Loss of height over time.
- A stooped posture.
- A bone that breaks much more easily than expected.
Is an increase in BMD good or bad?
However, BMD increases may also arise secondary to a range of underlying disorders affecting the skeleton. Although low BMD increases fracture risk, the converse may not hold for high BMD, since elevated BMD may occur in conditions where fracture risk is increased, unaffected or reduced.
At what age is bone density the highest?
Most people will reach their peak bone mass between the ages of 25 and 30. By the time we reach age 40, we slowly begin to lose bone mass. We can, however, take steps to avoid severe bone loss over time. For most of us, bone loss can be significantly slowed through proper nutrition and regular exercise.
Is it good to have high bone density?
The higher your bone mineral content, the denser your bones are. And the denser your bones, the stronger they generally are and the less likely they are to break.
