Osteoporosis is characterized by low bone mass that leads to an increased risk of fracture. The diagnosis can be confirmed by the finding of low bone mass, evidence of fracture on x-ray, a history of osteoporotic fracture, or height loss or kyphosis, indicative of vertebral (spinal) fracture Osteoporosis occurs in both males and females but is most common among women following the menopause, when bone turnover increases and the rate of bone resorption exceeds that of bone formation. Daily oral doses of alendronate (5,20, and 40 mg for six weeks) in postmenopausal women produced biochemical changes indicative of dose-dependent inhibition of bone resorption, including decreases in urinary calcium and urinary markers of bone collagen degradation (such as deoxypyridinoline and crosslinked N-telopeptides of type I collagen)

- Diagnosis can be confirmed by:
- Low bone mass
- Evidence of fracture on x-ray
- History of osteoporotic fracture
- Height loss or kyphosis
- Alendronate has been shown to produce biochemical changes indicative of dose-dependent inhibition of bone resorption in postmenopausal women, including decreases in urinary calcium and urinary markers of bone collagen degradation 1.
From the Research
To manage osteoporosis, I recommend a comprehensive approach including medication, lifestyle modifications, and regular monitoring, with first-line medications being bisphosphonates such as alendronate or zoledronic acid, and alternatives including denosumab or teriparatide for those who cannot tolerate bisphosphonates, as supported by the most recent study 2. Osteoporosis is a condition characterized by weakened bones that become fragile and more likely to break. The goal of treatment is to reduce the risk of fractures, which can have a significant impact on morbidity, mortality, and quality of life.
Medication Options
- Bisphosphonates, such as alendronate (70mg weekly) or zoledronic acid (5mg IV yearly), are effective in reducing the risk of vertebral, nonvertebral, and hip fractures in postmenopausal women with osteoporosis, as shown in a study published in the Journal of Internal Medicine 2.
- For those who cannot tolerate bisphosphonates, alternatives include denosumab (60mg subcutaneously every 6 months) or teriparatide (20mcg subcutaneously daily for up to 2 years), which have also been shown to be effective in reducing fracture risk 2.
Lifestyle Modifications
- Regular weight-bearing exercise, such as walking or resistance training, for 30 minutes most days can help maintain bone density and reduce the risk of falls.
- Fall prevention strategies, including home safety modifications, proper footwear, and vision checks, are crucial in reducing the risk of fractures.
Monitoring and Treatment Duration
- Bone density testing should be performed every 1-2 years to monitor treatment effectiveness, as recommended by a study published in the Journal of Internal Medicine 2.
- The duration of treatment with bisphosphonates should be limited to up to 10 years with oral bisphosphonates and 6 years with intravenous zoledronic acid, due to the risk of rare side effects, as noted in a study published in the BMJ 3.
- A drug holiday may be considered in patients who are not at high risk for fracture, but for those with a history of fragility fracture, the benefits of continuing therapy probably far outweigh the risk of harm, as discussed in a study published in the American Journal of Medicine 4.
