Causes & Risk Factors
Several factors can contribute to Abnormal Bone Density.
Abnormal bone density develops when the natural balance between bone formation and bone breakdown tips in the wrong direction.
Abnormal bone density develops when the natural balance between bone formation and bone breakdown tips in the wrong direction. Throughout your life, your body constantly removes old bone tissue and replaces it with new bone in a process called remodeling. Think of it like renovating a house room by room while you're still living in it. When you're young, your body builds new bone faster than it removes old bone, so your bone mass increases. After about age 30, this process reverses slightly, and you naturally lose a small amount of bone density each year.
Several factors can accelerate this bone loss beyond normal aging.
Several factors can accelerate this bone loss beyond normal aging. Hormonal changes play a major role, particularly the drop in estrogen that occurs during menopause in women. Estrogen helps protect bones, so when levels fall dramatically, bone loss speeds up significantly. Men experience a more gradual decline in testosterone, which also affects bone density but usually occurs later in life. Medical conditions can also disrupt normal bone remodeling. Overactive thyroid glands, inflammatory conditions like rheumatoid arthritis, and digestive disorders that affect nutrient absorption can all contribute to bone loss.
Certain medications, particularly corticosteroids used long-term for conditions like asthma or autoimmune diseases, can interfere with bone formation.
Certain medications, particularly corticosteroids used long-term for conditions like asthma or autoimmune diseases, can interfere with bone formation. Cancer treatments, including chemotherapy and hormone-blocking therapies, may also affect bone density. Additionally, lifestyle factors such as inadequate calcium and vitamin D intake, lack of weight-bearing exercise, excessive alcohol consumption, and smoking can all contribute to abnormal bone density over time.
Risk Factors
- Being female, especially after menopause
- Age over 50 years
- Family history of osteoporosis or fractures
- Small, thin body frame or low body weight
- Previous fracture after age 50
- Long-term use of corticosteroid medications
- Smoking cigarettes or using tobacco
- Excessive alcohol consumption
- Sedentary lifestyle with limited exercise
- Diet low in calcium and vitamin D
- Early menopause or surgical removal of ovaries
- Chronic diseases like rheumatoid arthritis or hyperthyroidism
Diagnosis
How healthcare professionals diagnose Abnormal Bone Density:
- 1
Diagnosing abnormal bone density typically begins when your doctor suspects you might be at risk based on your age, medical history, or a fracture that occurred with minimal trauma.
Diagnosing abnormal bone density typically begins when your doctor suspects you might be at risk based on your age, medical history, or a fracture that occurred with minimal trauma. The gold standard test is a DEXA scan (dual-energy X-ray absorptiometry), a painless procedure that takes about 10-15 minutes. You'll lie on a table while a scanner passes over your body, measuring bone density in your hip, spine, and sometimes forearm. The test uses very low levels of radiation, less than a chest X-ray, and requires no special preparation.

Your DEXA results are reported as T-scores, which compare your bone density to that of a healthy 30-year-old adult of the same gender.
Your DEXA results are reported as T-scores, which compare your bone density to that of a healthy 30-year-old adult of the same gender. A T-score of -1.0 or higher is considered normal, -1.0 to -2.5 indicates osteopenia (mild bone loss), and -2.5 or lower suggests osteoporosis. Your doctor may also order blood tests to check for underlying conditions that could be causing bone loss, such as thyroid problems, vitamin D deficiency, or kidney disease. These might include tests for calcium, phosphorus, vitamin D levels, and markers of bone turnover.

During diagnosis, your doctor will also assess your fracture risk using tools like the FRAX calculator, which considers your bone density along with other risk factors like age, weight, smoking history, and family history.
During diagnosis, your doctor will also assess your fracture risk using tools like the FRAX calculator, which considers your bone density along with other risk factors like age, weight, smoking history, and family history. This helps determine whether you need treatment and what type would be most appropriate. Sometimes additional imaging, like X-rays or CT scans, may be needed if you've had fractures or your doctor suspects other bone problems.
Complications
- The primary complication of abnormal bone density is fractures, which can occur with minimal trauma or even during normal daily activities.
- Hip fractures are among the most serious, often requiring surgery and leading to prolonged recovery periods.
- About 20% of people who suffer hip fractures don't survive the following year due to complications, and many others never regain their previous level of independence.
- Vertebral compression fractures in the spine can cause chronic pain, height loss, and the characteristic hunched posture known as kyphosis or "dowager's hump." Beyond the physical impact, fractures can significantly affect quality of life and mental health.
- Many people develop fear of falling, leading to reduced activity and social isolation.
- This inactivity can create a downward spiral, further weakening bones and muscles while increasing depression risk.
- However, with proper treatment and fall prevention strategies, many complications can be avoided or minimized.
- Early intervention, appropriate medication when needed, and maintaining an active lifestyle significantly reduce fracture risk and help preserve independence and quality of life well into older age.
Prevention
- Preventing abnormal bone density starts with building strong bones during childhood and young adulthood, then maintaining bone health throughout life.
- The peak bone mass you achieve by age 30 serves as your "bone bank account" for later years, so early prevention efforts pay lifelong dividends.
- Key strategies include getting adequate calcium and vitamin D through diet or supplements, engaging in regular weight-bearing exercise, avoiding smoking and excessive alcohol, and maintaining a healthy body weight.
- For adults, prevention focuses on slowing the natural bone loss that occurs with aging.
- This includes consuming 1,000-1,200 mg of calcium daily through dairy products, leafy greens, sardines, or supplements, along with 800-1,000 IU of vitamin D.
- Regular exercise remains crucial - aim for weight-bearing activities like walking, jogging, or dancing combined with resistance training at least twice weekly.
- Balance exercises become increasingly important as you age to prevent falls that could lead to fractures.
- While you can't prevent all risk factors for bone loss, such as aging or genetics, addressing modifiable factors makes a significant difference.
- This includes working with your doctor to minimize bone-damaging medications when possible, treating conditions that affect bone health like hyperthyroidism, and making home safety improvements to reduce fall risk.
- Regular bone density screening starting at age 65 for women and 70 for men, or earlier if you have risk factors, allows for early detection and intervention before significant bone loss occurs.
Treatment for abnormal bone density focuses on slowing bone loss, increasing bone formation when possible, and preventing fractures.
Treatment for abnormal bone density focuses on slowing bone loss, increasing bone formation when possible, and preventing fractures. The approach depends on your T-score, fracture risk, age, and overall health. For people with osteopenia and low fracture risk, lifestyle changes alone might be sufficient. However, those with osteoporosis or high fracture risk typically need medication along with lifestyle modifications.
Several types of medications can help improve bone density.
Several types of medications can help improve bone density. Bisphosphonates are often the first choice and include drugs like alendronate, risedronate, and zoledronic acid. These medications slow bone breakdown and are generally taken weekly, monthly, or yearly depending on the specific drug. Denosumab is an injection given every six months that works differently by blocking cells that break down bone. For postmenopausal women, selective estrogen receptor modulators like raloxifene can help maintain bone density. In severe cases, bone-building medications like teriparatide or abaloparatide may be prescribed for up to two years.
Lifestyle changes form the foundation of treatment regardless of medication use.
Lifestyle changes form the foundation of treatment regardless of medication use. Weight-bearing and resistance exercises help stimulate bone formation - activities like walking, dancing, tennis, and strength training are particularly beneficial. Aim for at least 30 minutes of weight-bearing exercise most days. Adequate calcium (1,000-1,200 mg daily) and vitamin D (800-1,000 IU daily) intake is essential, whether through diet or supplements. Balance and fall prevention exercises, such as tai chi or yoga, help reduce fracture risk by improving stability and strength.
New treatments continue to emerge from ongoing research.
New treatments continue to emerge from ongoing research. Romosozumab, a newer bone-building medication, can be used for one year in postmenopausal women with high fracture risk. Scientists are also investigating combinations of different medications and exploring how genetic testing might help personalize treatment choices. Regular monitoring with DEXA scans every two years helps track treatment effectiveness and guide adjustments to your care plan.
Living With Abnormal Bone Density
Living well with abnormal bone density requires a proactive approach that balances protecting your bones while maintaining an active, fulfilling life. Many people initially feel overwhelmed by the diagnosis, but with the right strategies, you can significantly reduce your fracture risk and continue enjoying most activities. Focus on creating a bone-healthy daily routine that includes taking medications as prescribed, engaging in appropriate exercise, and ensuring adequate nutrition. Weight-bearing activities like walking, dancing, or tennis, combined with strength training, help maintain bone and muscle strength while improving balance and coordination.
