Your Primary Care Physician: The First Step
For most individuals, a primary care provider (PCP), such as a family doctor or an internist, is the first point of contact for routine health concerns, including initial screenings for bone health. PCPs are equipped to order a bone mineral density (BMD) test, most commonly a DEXA scan, to assess your bone health based on age and risk factors. A PCP will consider several factors when deciding if and when to order a bone density check. They will evaluate your overall health, medical history, and lifestyle, as well as family history of osteoporosis and whether you are experiencing symptoms like loss of height or a fracture from a minor fall. They can also discuss basic preventive measures, such as dietary and exercise recommendations, and can monitor your bone density over time, especially if you have been diagnosed with osteopenia.
When to Consider a Bone Density Check
Your PCP will assess if you meet the criteria for a bone density test. Common reasons to schedule a check include:
- Age: Women over 65 and men over 70 are often recommended for routine screening.
- Early Menopause: For women, a drop in estrogen levels after menopause is a significant risk factor.
- Fractures: If you have broken a bone after age 50 from a minor fall.
- Medications: Long-term use of certain medications, such as corticosteroids, can increase bone loss.
- Medical Conditions: Certain conditions like rheumatoid arthritis, liver disease, or kidney disease increase osteoporosis risk.
Medical Specialists for Advanced Bone Health
If your PCP's initial evaluation reveals low bone density or if your case is complex, they may refer you to a specialist. Each specialist focuses on a different aspect of osteoporosis and bone health.
Endocrinologists
Endocrinologists specialize in hormonal disorders and metabolic diseases. Since hormones like estrogen, testosterone, and parathyroid hormone play a crucial role in regulating bone density, a hormonal imbalance can be an underlying cause of osteoporosis. They can provide specialized treatment plans involving hormone-based therapies or other medications to address the root cause of bone loss.
Rheumatologists
Rheumatologists treat inflammatory conditions that can affect bones, joints, muscles, and tendons. Conditions such as rheumatoid arthritis, psoriatic arthritis, and systemic lupus erythematosus are known risk factors for osteoporosis. A rheumatologist can manage the inflammation that may contribute to bone loss and coordinate treatment with other specialists.
Geriatricians
Geriatricians are specialists in the healthcare of older adults. They have extensive experience managing osteoporosis in tandem with other age-related health concerns, including balance and mobility issues that increase fall risk. They can order DEXA scans and blood tests, and prescribe medications suitable for elderly patients.
Gynecologists
Given that menopause is a major risk factor for osteoporosis in women, gynecologists are often involved in bone health screening and management. They can order DEXA scans and counsel postmenopausal women on preventative measures, including hormone replacement therapy.
The Bone Density Test: What to Expect
The DEXA Scan Procedure
A Dual-energy X-ray Absorptiometry (DEXA) scan is a simple, non-invasive imaging test that measures bone mineral density. The scan is performed by a trained radiographer, and the results are interpreted by a radiologist. During the procedure:
- You lie on a padded table while a mechanical arm passes over your body.
- You will need to remain still for a few minutes while the scan is being performed.
- The scan typically focuses on the hip and spine, as these are common areas for osteoporosis-related fractures.
Interpreting the DEXA Results
After the scan, the results are presented as T-scores and Z-scores.
- T-score: Compares your bone density to that of a healthy young adult. A score above -1 is considered normal, while a score between -1 and -2.5 indicates osteopenia (low bone mass), and a score below -2.5 indicates osteoporosis.
- Z-score: Compares your bone density to other people of your age, size, and gender. An unusually high or low Z-score might suggest an underlying condition that requires further testing.
Comparison of Bone Health Specialists
| Specialist | Primary Role in Bone Health | When to See One |
|---|---|---|
| Primary Care Physician | Initial screening, diagnosis, and long-term management of mild to moderate osteoporosis. | First point of contact for routine check-ups and screening based on age and risk factors. |
| Endocrinologist | Management of hormonal imbalances affecting bone density. | If osteoporosis is suspected to be related to hormone issues (e.g., menopause, thyroid problems). |
| Rheumatologist | Treatment of inflammatory conditions that contribute to bone loss. | If an autoimmune or inflammatory condition, like rheumatoid arthritis, is present. |
| Gynecologist | Monitoring bone health in women, especially post-menopause. | For women concerned about bone health after menopause or experiencing hormone changes. |
| Geriatrician | Management of osteoporosis in older adults, considering fall risk and other comorbidities. | If you are an older adult with complex health needs related to aging and bone health. |
Proactive Steps Beyond a Bone Density Check
While knowing what type of doctor checks bone density is the starting point, maintaining strong bones involves more than just testing. Your doctor may recommend lifestyle modifications as part of your treatment plan.
Lifestyle and Nutritional Recommendations
- Weight-Bearing Exercise: Activities like walking, jogging, and weightlifting can help build bone density and improve strength.
- Adequate Calcium and Vitamin D: Ensuring proper intake of these nutrients is crucial for bone health. Your doctor may recommend supplements if your dietary intake is insufficient.
- Fall Prevention: Taking steps to reduce the risk of falls, such as balance training or using assistive devices, is particularly important for individuals with low bone density.
- Smoking Cessation and Limiting Alcohol: Both smoking and excessive alcohol consumption are risk factors for osteoporosis.

Conclusion
Ultimately, your primary care physician is the central figure in your bone health journey, initiating the process of checking your bone density and coordinating care. However, a multidisciplinary approach involving specialized doctors like endocrinologists, rheumatologists, and others is often necessary for comprehensive management, particularly in complex cases. By working closely with your healthcare team, you can take control of your bone health and significantly reduce your risk of fractures as you age. The key is to start the conversation with your doctor about your risk factors and when a bone density check is right for you. Early detection and proactive management are your best defense against osteoporosis and its potential complications.
