How is osteoporosis treated once it has been diagnosed?

According to the Bone Health & Osteoporosis Foundation, more than 10 million Americans have osteoporosis. Following a diagnosis, effective management involves a comprehensive plan that includes both medication and significant lifestyle adjustments tailored to slow bone loss and prevent fractures.

Quick Summary

Treatment for a new osteoporosis diagnosis involves a personalized plan incorporating medication to prevent bone breakdown or stimulate bone growth, along with key lifestyle modifications. This approach aims to reduce fracture risk and maintain bone mineral density.

Key Points

• Start with Medication: Pharmacologic therapy is often initiated after diagnosis, with bisphosphonates and denosumab being common first-line options for many patients.

• Choose Medication Based on Severity: Anabolic or bone-building drugs are reserved for more severe cases or when standard therapies are ineffective or not tolerated.

• Integrate Lifestyle Changes: Treatment should always be combined with a bone-healthy diet rich in calcium and vitamin D, as well as weight-bearing and muscle-strengthening exercises.

• Focus on Fall Prevention: For individuals with osteoporosis, preventing falls is critical to avoid fractures. This involves home safety modifications and balance exercises.

• Work with a Care Team: A holistic approach involves a team of healthcare professionals, including doctors, physical therapists, and nutritionists, to create a personalized and effective management plan.

• Understand Treatment Duration: Many treatments have specific timeframes, like bisphosphonate holidays or limited courses of anabolic drugs, requiring strategic long-term planning with a physician.

A Comprehensive Approach to Osteoporosis Treatment

After an osteoporosis diagnosis, the primary goal of treatment is to prevent fractures by slowing bone loss, improving bone density, and reducing the risk of falls. Your healthcare provider will use your bone mineral density (BMD) test results and fracture risk assessment (FRAX) score to formulate a plan. This plan will likely involve a combination of pharmacologic therapy and lifestyle modifications.

Pharmacologic Treatments: Antiresorptive vs. Anabolic Drugs

Medications for osteoporosis fall into two main categories: antiresorptive drugs, which slow the natural breakdown of bone, and anabolic drugs, which stimulate new bone formation. The choice of medication depends on the severity of the osteoporosis and individual health factors.

Antiresorptive Medications

These are the most common and often first-line treatments for osteoporosis.

• Bisphosphonates: This class of drugs works by inhibiting the cells that break down bone tissue. Common examples include:
  • Alendronate (Fosamax)
  • Risedronate (Actonel)
  • Ibandronate (Boniva)
  • Zoledronic acid (Reclast) Oral bisphosphonates are typically taken at regular intervals, while zoledronic acid is administered via intravenous (IV) infusion on a less frequent schedule. After a certain period, a doctor might recommend a 'drug holiday' to decrease the risk of rare side effects, such as osteonecrosis of the jaw or atypical femoral fractures.
• Denosumab (Prolia): Delivered as a subcutaneous injection on a schedule determined by a healthcare provider, this monoclonal antibody inhibits the formation of cells that break down bone. It is often used for patients who cannot tolerate or have not responded well to bisphosphonates. Consistency with the prescribed schedule is key, as stopping the medication can lead to an increased risk of spinal fractures.
• Raloxifene (Evista): This selective estrogen receptor modulator (SERM) mimics estrogen's beneficial effects on bone density in postmenopausal women. It is not as effective as other treatments in preventing non-spinal fractures but can reduce the risk of invasive breast cancer.

Anabolic (Bone-Building) Medications

These powerful drugs are typically reserved for those with severe osteoporosis or a very high risk of fractures.

• Teriparatide (Forteo) and Abaloparatide (Tymlos): These are parathyroid hormone analogs that stimulate new bone formation. They are administered via daily self-injection for a limited time and must be followed by a bone-stabilizing medication to maintain the new bone growth.
• Romosozumab (Evenity): This is a newer monoclonal antibody that both stimulates bone formation and reduces bone resorption. It is given as a monthly injection for a defined period, followed by another osteoporosis medication. It is not recommended for those who have had a heart attack or stroke in the past year.

Lifestyle Modifications for Managing Osteoporosis

Medication should always be used in conjunction with a bone-healthy lifestyle. These changes are crucial for maximizing treatment efficacy and preventing falls.

• Nutritional Support: A diet rich in calcium and vitamin D is fundamental for bone health.
  • Calcium Sources: Include low-fat dairy products, dark leafy green vegetables (like broccoli, kale, and spinach), salmon, and fortified foods such as cereals and orange juice. Healthcare providers can advise on appropriate daily calcium intake.
  • Vitamin D: Helps the body absorb calcium effectively. Sources include sun exposure, fatty fish, egg yolks, and fortified milk. Many adults may require vitamin D supplementation to meet recommended levels.
• Exercise: Weight-bearing and resistance exercises stimulate bone growth and improve muscle strength, balance, and agility.
  • Weight-Bearing: Walking, jogging, stair climbing, dancing, and hiking.
  • Resistance: Lifting weights, using resistance bands, or bodyweight exercises.
  • Balance: Tai chi, yoga, and posture exercises are essential for fall prevention.
• Avoiding Harmful Habits: Modifying certain lifestyle choices can slow bone loss.
  • Smoking Cessation: Smoking increases bone loss and the risk of fracture.
  • Limiting Alcohol: Heavy alcohol consumption can interfere with calcium and vitamin D absorption and increase fall risk.
• Fall Prevention: Taking precautions at home is vital for preventing fractures.
  • Remove throw rugs and clutter.
  • Install grab bars in bathrooms.
  • Ensure rooms are brightly lit.
  • Wear low-heeled shoes with non-slip soles.

Conclusion

Effectively treating osteoporosis once it has been diagnosed requires a multifaceted strategy. No single approach is a cure, but rather a long-term management plan aimed at minimizing bone loss and preventing fractures. By combining appropriate medication, such as first-line bisphosphonates or specialized anabolic agents, with essential lifestyle changes, individuals can significantly improve their bone health and quality of life. Working closely with a healthcare team—including doctors, physical therapists, and nutritionists—is crucial for personalizing the plan and staying on track. A structured approach to diet, exercise, and fall prevention is the best defense against further complications from this silent disease.
