This article will help you understand the bone density test and how to prepare for it.
What Is a Bone Density Test?
A bone density test measures the strength or weakness of bones by assessing X-ray absorption (DXA), a type of bone X-ray. This test uses low levels of radiation and involves passing a scanner over the body while lying on a padded table.
When Should You Have a Bone Density Test?
A bone density test is recommended:
- For all women aged 65 years and above.
- For women under 65 with risk factors increasing the chance of developing osteoporosis.
- For individuals with risk factors that increase the likelihood of developing osteoporosis.
Factors increasing the chance of developing osteoporosis:
- Menopause and lower hormone levels.
- A history of previous fractures.
- If you are a man with health issues related to bone density loss, such as rheumatoid arthritis or chronic kidney or liver diseases.
- If you use medications known to cause bone density loss.
- Suffering from type 1 diabetes, liver diseases, kideny disorders, or having a family history of osteoporosis.
- Having thyroid disorders, such as hyperthyroidism.
- Suffer from parathyroid gland disorders, such as hyperparathyroidism.
- Exhibit symptoms and signs of osteoporosis.
- In cases of height loss, as individuals who have lost at least 3.8 cm of their height may suffer from spinal compression fractures due to osteoporosis.
The significance of a bone density test lies in determining the extent of bone density loss before fractures occur and confirming and diagnosing osteoporosis.
You can prevent and reduce the risk of osteoporosis by:
- Exercising regularly.
- Following a healthy diet rich in calcium and vitamin D.
- Quitting smoking. For more details, here is a guide on quitting smoking.
