The goal of osteoporosis treatment is to increase bone density, reduce fracture risk, and improve patients' quality of life. Treatment modalities 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 mineral density loss, and fracture history.
The primary objectives are to inhibit bone resorption, promote bone formation, and incorporate 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 divided into anti-resorptive agents and anabolic agents. Bisphosphonates (such as 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 (such as teriparatide) stimulate osteoblast activity and are suitable for patients with severe bone loss. Additionally, monoclonal antibodies like 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 fracture risk over 10 years using DEXA scans and tools like FRAX to determine the necessity of treatment and appropriate medication choices.
Oral bisphosphonates are usually taken daily or weekly, with plenty of water to avoid esophageal irritation. Injectable medications like denosumab are administered subcutaneously every 6 months, while parathyroid hormone analogs require daily subcutaneous injections for 24 weeks.
Dosage adjustments depend on renal function; for example, those with a creatinine clearance below 35 mL/min should avoid certain bisphosphonates. Strict adherence to dosing intervals is crucial to ensure proper accumulation of the medication in bone tissue.
Non-pharmacological interventions 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, requiring 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 should not be used in these cases. Patients on anticoagulants require caution with bisphosphonates due to the risk of ONJ.
Pregnant or breastfeeding women must avoid bone resorption inhibitors. Prior to treatment, exclude the possibility of bone metastases, as these drugs may exacerbate pathological fractures.
Calcium supplements should be taken at least 2 hours apart from bisphosphonates to prevent absorption interference. Long-term steroid use can diminish drug efficacy, necessitating dose adjustments or combination therapy.
When combined with diuretics, blood calcium levels should be monitored to prevent metabolic imbalance. SERMs may interact with anticoagulants, requiring dose adjustments of anticoagulant therapy.
Large clinical trials show that intravenous zoledronate reduces vertebral fracture risk by 70%, with effects lasting over three years. Denosumab increases bone density by approximately 8-9% by the 12th month of treatment.
Systematic reviews confirm that resistance training reduces fall risk by 16%, and combined pharmacotherapy can significantly slow 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. Fitness training emphasizes weight-bearing and balance exercises to enhance bone strength and functional capacity.
If medications are poorly tolerated, options such as raloxifene or travoprost (progabalin) may be considered as selective bone resorption modulators. For severe bone loss, experimental therapies like mesenchymal stem cell transplantation may be explored, but only in specialized teaching hospitals.
Bisphosphonate use may cause loss of appetite or heartburn. It is recommended to take the medication with 300 mL of warm water and remain upright for 30 minutes to prevent reflux. If symptoms persist, discuss with your physician 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 green vegetables, and fortified foods. During the initial phase of treatment, calcium supplements should be taken at least 2 hours apart from medications, and high-phytate whole grains should be avoided to maximize absorption.
Can treatment be stopped immediately after bone density improves?Bone density improvement indicates treatment effectiveness, but stopping medication may lead to a recurrence of bone loss. Physicians usually 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 6 months, as these drugs can affect lipid metabolism. Patients with a history of atherosclerosis may need to take statins or engage in 150 minutes of weekly aerobic exercise to reduce cardiovascular burden.
Which types of exercise should be avoided when combining physical therapy with medication?High-impact exercises such as running or jumping should be avoided during medication therapy. Resistance training (e.g., resistance bands), aquatic exercises, and balance training are recommended. Patients with vertebral fracture risk should avoid forward bending and instead perform lateral stretches or spinal extension exercises to strengthen core muscles.
