Maintaining strong and healthy bones is crucial for overall well-being, especially for women as they age. Osteoporosis, a condition characterized by weakened bones, poses a significant health risk, leading to fractures and long-term disability. Fortunately, early detection and intervention can make a substantial difference. The DEXA (Dual-energy X-ray Absorptiometry) scan offered at Christiana Care provides a quick, painless, and highly effective way to assess your bone health and risk of osteoporosis.

A DEXA scan, also known as a bone density scan, is a medical imaging test that measures bone mineral density. This procedure is essential for identifying osteoporosis and osteopenia (lower than normal bone density) before fractures occur. The process is straightforward: you lie on a padded table while a DEXA scanner arm passes over your body, emitting low-dose X-rays. These X-rays differentiate between bone and soft tissue, allowing the machine to accurately measure the amount of calcium and other minerals in your bones. The test is remarkably fast, typically taking only about 15 minutes, and the radiation exposure is minimal – less than that of a single dental X-ray.
Why is a DEXA scan particularly important for women? Women are disproportionately affected by osteoporosis. Statistics show that 80 percent of all osteoporosis-related fractures occur in women. This is largely due to biological factors. Women naturally have smaller and less dense bones than men. Furthermore, the hormonal changes associated with menopause, specifically the decline in estrogen production, lead to a rapid decrease in bone density. This makes post-menopausal women particularly vulnerable to bone loss and fractures. Detecting low bone mass early through a DEXA scan allows for timely interventions and preventative measures, significantly reducing the risk of debilitating fractures, especially hip fractures, which carry serious health consequences.
Understanding your individual risk factors for osteoporosis is the first step in proactive bone health management. Several factors can increase a woman’s likelihood of developing osteoporosis. A personal checklist can help determine if you should discuss DEXA screening with your healthcare provider. Risk factors include:
- Smoking History: Smoking has been linked to decreased bone density and increased fracture risk.
- Low Body Weight: Women weighing under 127 pounds may have less bone mass to begin with, increasing their vulnerability.
- Family History of Fractures: A family history of osteoporosis or fractures, especially hip fractures in a parent, increases your risk.
- Early Menopause: Whether natural or surgically induced (ovary removal), early menopause leads to earlier estrogen decline and bone loss.
- Certain Medications: Long-term use of corticosteroids like prednisone, anti-seizure medications such as Dilantin, and aromatase inhibitors used in breast cancer treatment can negatively impact bone density.
- Height Loss: Even subtle decreases in height over time can be an indicator of vertebral compression fractures, often a sign of underlying osteoporosis.
Beyond regular DEXA scans, adopting a bone-healthy lifestyle is crucial for prevention. While genetic predisposition plays a role, lifestyle choices significantly influence bone health. Ensuring adequate calcium intake through diet or supplements is vital, as calcium is the building block of bones. Vitamin D, essential for calcium absorption, is primarily obtained through sunlight exposure and can also be supplemented. Regular weight-bearing exercise, such as walking, jogging, or dancing, helps strengthen bones.
Preventing falls is another critical aspect of protecting bone health, especially as we age. Most falls occur at home and are often preventable. Simple home modifications can significantly reduce fall risk. Ensure adequate lighting, particularly in hallways and stairways. Use non-skid rugs and mats to prevent slipping. Be extra cautious around pets that could be tripping hazards. If you experience dizziness, consult your doctor to address potential balance issues. Excessive alcohol consumption (more than two to three drinks daily) can not only increase fall risk but also directly weaken bones.
Christiana Care provides accessible and convenient DEXA scan services at four locations throughout New Castle County: Greenville, Newark, North Wilmington, and Smyrna. To schedule a DEXA scan, you will need a prescription from your doctor. Discuss with your healthcare provider whether a bone density scan is appropriate for you based on your risk factors. Once you have a prescription, you can easily schedule your examination by calling 302-838-3088.
The results of your DEXA scan will be promptly shared with both you and your primary care physician. Should further evaluation or treatment be necessary, Christiana Care offers seamless access to a multidisciplinary team of specialists. Consultations with rheumatologists, endocrinologists, gynecologists, and primary care physicians with specialized expertise in bone health are readily available within Christiana Care’s comprehensive ambulatory care network.
