Osteoporosis, often described as a "silent disease," is characterized by weakened and brittle bones that become increasingly prone to fractures. This condition generally goes unnoticed until a bone actually breaks, making it a significant public health concern, especially among older adults. Dr. T.G. Prabhakar, Consultant Orthopaedic & Joint Replacement Surgeon at Kauvery Hospital in Tirunelveli, offers a comprehensive understanding of osteoporosis, from its risk factors and subtle signs to its diagnosis and management.
This article highlights not only the challenges posed by osteoporosis but also the proactive steps individuals can take to mitigate these risks, providing a valuable resource for those concerned about maintaining strong, healthy bones into older age.
Osteoporosis results from an imbalance in the bone remodeling process, where bone mass is lost faster than it's created, leading to porous, fragile bones. It primarily affects older adults, particularly women post-menopause, due to significant drops in estrogen—a key hormone in maintaining bone density. However, men are not spared, as diminishing testosterone levels with age can similarly impact bone strength.
"Bone health is not just a concern for the elderly; it begins earlier than we think. It's crucial to address the factors contributing to bone loss throughout life," explains Dr. Prabhakar.
The risk of developing osteoporosis escalates with age, but genetics also play a role. A family history of osteoporosis or related fractures significantly raises one's risk. Lifestyle factors such as insufficient physical activity, poor diet lacking in calcium and vitamin D, smoking, and excessive alcohol consumption can further exacerbate bone loss. Certain medical conditions and medications, including rheumatoid arthritis, celiac disease, prolonged use of corticosteroids, and specific anti-seizure drugs, also heighten the risk.
Detecting osteoporosis before a fracture occurs can be challenging due to its asymptomatic nature. However, some early signs might hint at compromised bone health. These include recurrent back pain, a stooped posture, loss of height over time, and even changes in nail and dental health. Dr. Prabhakar emphasizes the importance of recognizing these early symptoms: "Subtle signs like a weakened grip or difficulty in performing routine tasks such as opening a jar or getting up from a chair can be early indicators of reduced bone strength."
The most reliable method for diagnosing osteoporosis is the Dual-energy X-ray absorptiometry (DEXA) scan. This test measures bone mineral density at critical sites like the hip and spine and is essential for assessing the extent of bone loss. "DEXA scans are quick, precise, and involve minimal radiation, making them ideal for routine screening and monitoring of osteoporosis," Dr. Prabhakar notes.
An active lifestyle is crucial in combating osteoporosis. Weight-bearing exercises, such as walking, running, or resistance training, can significantly improve bone density. Nutritional choices also play a critical role. Diets rich in calcium, protein, and vitamin D are essential for bone health. Dr. Prabhakar advises, "Incorporating dairy products, leafy greens, nuts, and fortified foods can help maintain strong bones and prevent osteoporosis."
Treating osteoporosis involves a multifaceted approach. Alongside lifestyle modifications, medications play a key role in managing the condition. Bisphosphonates are commonly prescribed to slow bone degradation and improve bone density. For patients who experience side effects from oral bisphosphonates, alternatives like injectable Teriparatide and Denosumab are available.
"Medication needs to be tailored to individual needs, and in conjunction with lifestyle changes, can significantly reduce the risk of fractures," explains Dr. Prabhakar.
Dr. Prabhakar recommends several preventive measures to improve safety and reduce the risk of falls and fractures for those with osteoporosis. These include installing non-slip flooring, using assistive devices such as walking sticks, and modifying living spaces to make them more accessible. Regular check-ups and using tools like the FRAX tool to assess fracture risks can guide appropriate interventions.
Osteoporosis remains a major health issue, but with informed strategies and interventions, it can be effectively managed. Dr. Prabhakar's insights emphasize the importance of early detection, appropriate lifestyle changes, and medical interventions in maintaining bone health and enhancing quality of life for those at risk or already affected by osteoporosis.
