The goal of osteoporosis treatment is to increase bone density, reduce fracture risk, and improve patients' quality of life. Treatment methods include pharmacotherapy, nutritional supplementation, exercise training, and, when necessary, surgical interventions. Physicians tailor personalized treatment plans based on the patient's age, degree of bone density loss, and fracture history.
Main objectives include suppressing bone resorption, promoting bone formation, and incorporating preventive care to avoid secondary fractures. Monitoring for medication side effects and lifestyle adjustments to strengthen bone health are also essential components of treatment.
Pharmacological treatments are categorized into anti-resorptive agents and anabolic agents. Bisphosphonates (e.g., Alendronate) directly act on osteoclasts to slow bone loss; Selective Estrogen Receptor Modulators (SERMs) mimic estrogen's protective effects on bones without affecting other tissues.
Parathyroid hormone analogs (e.g., Teriparatide) stimulate osteoblast activity and are suitable for severe osteoporosis cases. Additionally, monoclonal antibodies such as Denosumab selectively neutralize factors related to osteoclasts, reducing bone resorption.
Suitable candidates include patients diagnosed with a T-score below -2.5, those who have experienced fragility fractures, or individuals with secondary osteoporosis due to long-term steroid use. High-risk groups such as postmenopausal women, those with a positive family history, or individuals with decreased physical resilience are also recommended for preventive treatment.
Doctors assess the 10-year fracture risk using DEXA scans and tools like FRAX to determine the necessity of treatment and appropriate medication choices.
Oral bisphosphonates are typically taken daily or weekly, with plenty of water to prevent esophageal irritation. Injectable medications like Denosumab are administered via subcutaneous injection every six months, while parathyroid hormone analogs require daily subcutaneous injections for 24 weeks.
Dosage adjustments depend on renal function; for example, bisphosphonates should be avoided in patients with a creatinine clearance below 35 mL/min. Strict adherence to dosing intervals is crucial to ensure proper accumulation of the medication in bone tissue.
Non-pharmacological treatments such as resistance training can enhance muscle strength and balance, reducing fall risk. A holistic medical approach combining multiple interventions can significantly improve long-term patient outcomes.
Oral bisphosphonates may cause esophagitis, musculoskeletal pain, and rarely, osteonecrosis of the jaw (ONJ). Denosumab may temporarily elevate serum creatinine levels, necessitating regular renal function monitoring.
Serious side effects include:
Contraindications include severe renal impairment (GFR<30 mL/min/1.73 m²) and esophageal disorders; oral bisphosphonates are not recommended for these patients. Patients on anticoagulants should use bisphosphonates cautiously due to the risk of ONJ. Pregnant or breastfeeding women must avoid bone resorption inhibitors. Prior to treatment, rule out bone metastases, as these drugs may exacerbate pathological fractures.
Calcium supplements should be taken at least 2 hours apart from bisphosphonates to avoid absorption interference. Long-term corticosteroid use can diminish drug efficacy, requiring dose adjustments or combination therapy.
When combined with diuretics, monitor blood calcium levels to prevent metabolic imbalance. SERMs may interact with anticoagulants, necessitating dose adjustments to anticoagulant therapy.
Large clinical trials show that intravenous zoledronate reduces vertebral fracture risk by 70% with effects lasting over three years. Denosumab increases bone mineral density by approximately 8-9% at 12 months. Systematic reviews confirm that resistance training reduces fall risk by 16%, and combined therapy significantly slows bone loss. The 2020 Cochrane review verified that bisphosphonates decrease non-vertebral fracture risk by 20%.
Non-pharmacological approaches include daily intake of 1200-1500 mg of calcium and 800-1000 IU of vitamin D, which form the foundation of all treatment plans. Physical fitness training emphasizes weight-bearing and balance exercises to enhance bone strength and functional ability.
For those intolerant to medications, options include selective bone resorption modulators like Raloxifene or Trapezium (progabalin). Severe osteoporosis may consider experimental therapies such as mesenchymal stem cell transplantation, but these should be conducted in teaching hospitals.
Bisphosphonate use can cause loss of appetite or heartburn. It is recommended to take the medication with 300 cc of warm water and remain upright for 30 minutes to prevent reflux. If symptoms persist, discuss with your doctor about adjusting the dose or switching to periodic injections, which can also reduce gastrointestinal burden.
How should diet be adjusted during treatment to optimize drug efficacy?Daily intake of 1200-1500 mg of calcium and 800-1000 IU of vitamin D is essential, preferably from low-fat dairy, dark leafy greens, and fortified foods. During early treatment, calcium supplements should be taken at least 2 hours apart from medication, and avoid consuming high-phytate whole grains simultaneously to ensure absorption.
Can treatment be stopped immediately after improvements in bone density?Bone density improvement indicates treatment effectiveness, but stopping medication may lead to a loss of bone mass. Physicians typically recommend continuing treatment for at least 3-5 years and adjusting the plan based on bone turnover markers such as serum C-terminal telopeptide. Elderly patients or those at high fracture risk may require long-term maintenance therapy.
What cardiovascular risks should patients on hormone therapy be aware of?When using SERMs, blood lipids and blood pressure should be monitored every six months, as these drugs can affect lipid metabolism. Patients with a history of atherosclerosis may be prescribed statins or advised to engage in 150 minutes of aerobic exercise weekly to reduce cardiovascular risk.
Which types of exercise should be avoided when combining physical therapy with medication?During pharmacotherapy, high-impact exercises such as running or jumping should be avoided. Instead, resistance training (e.g., resistance bands), aquatic exercises, and balance training are recommended. Patients at risk of spinal fractures should avoid forward bending and instead focus on lateral stretching or spinal extension exercises to strengthen core muscles.
