Bone mineral density (BMD) is a measure of the amount of mineral content, primarily calcium and phosphorus, present in bone tissue. It serves as a key indicator of bone strength and density, providing valuable information about bone health and the risk of fractures. BMD is typically assessed through a specialized imaging technique known as dual-energy X-ray absorptiometry (DXA or DEXA).
BMD testing is commonly used in the diagnosis and management of osteoporosis, a condition characterized by low bone mass and deterioration of bone tissue, leading to an increased risk of fractures. By identifying individuals at risk for osteoporosis or osteopenia (low bone density), BMD testing enables healthcare providers to implement preventive measures, such as lifestyle modifications, dietary changes, and medication therapy, to reduce the risk of fractures and maintain bone health.
