Osteoporosis is a metabolic bone disease characterized by decreased bone density and quality, leading to an increased risk of fractures. It commonly affects older adults, especially postmenopausal women, due to hormonal changes that affect bone metabolism. This condition often progresses silently, with many individuals unaware of their declining bone health until a fracture occurs.

Several factors increase the risk of developing osteoporosis, including advanced age, gender, family history, and certain medical conditions such as rheumatoid arthritis and hyperthyroidism. Lifestyle choices, such as a diet low in calcium and vitamin D, lack of physical activity, excessive alcohol consumption, and smoking, further contribute to the likelihood of this disease. Additionally, certain medications, such as long-term use of corticosteroids, can impair bone density.

Osteoporosis is often called a 'silent disease' because it usually does not exhibit symptoms until a fracture occurs, typically from a minor fall or injury. Common fracture sites include the hip, wrist, and spine, with vertebral fractures potentially leading to chronic pain, height loss, and a stooped posture. Individuals may also experience bone tenderness or the development of a hump in the upper back as a result of compromised spinal vertebrae.

Osteoporosis is primarily caused by an imbalance between bone resorption and bone formation, leading to a decrease in bone density. This condition can be attributed to various factors, including aging, hormonal changes (particularly a decrease in estrogen in women post-menopause), inadequate intake of calcium and vitamin D, sedentary lifestyle, and certain medical conditions such as hyperthyroidism or rheumatoid arthritis. Additionally, excessive alcohol consumption and smoking can further exacerbate bone loss.

The diagnosis of osteoporosis typically involves a dual-energy X-ray absorptiometry (DEXA) scan, which measures bone mineral density (BMD). A T-score of -2.5 or lower indicates osteoporosis, while a T-score between -1 and -2.5 signifies osteopenia, a precursor condition. Physicians may also assess fracture risk using clinical risk factors and/or tools like the FRAX calculator.

The management of osteoporosis typically involves a multifaceted approach that includes lifestyle modifications, nutritional interventions, and pharmacotherapy. Patients are often advised to engage in weight-bearing exercises, consume a diet rich in calcium and vitamin D, and avoid risk factors such as tobacco and excessive alcohol. Pharmacological treatments may include bisphosphonates, selective estrogen receptor modulators, or parathyroid hormone analogs, aimed at increasing bone density and reducing fracture risk.

Preventing osteoporosis involves a multifaceted approach focusing on lifestyle modifications, including a balanced diet rich in calcium and vitamin D, regular weight-bearing and muscle-strengthening exercise, and avoidance of tobacco and excessive alcohol. Early screening and risk assessment are crucial, especially for individuals with a family history or other risk factors. In some cases, healthcare providers may recommend medications to preserve bone density in at-risk populations.
