About Bone Mineral Density
Bone Mineral Density (BMD) is a measurement of the concentration of minerals such as calcium in a defined area of bone. This is an essential marker for diagnosing bone health, primarily osteoporosis and fracture risk. BMD values help assess the strength and density of bones, emphasizing structural integrity and overall skeletal resilience.
Reference Values
Optimal Range
≥ 3.0 Z score
Elite Value
3.0 Z score
Health Implications
High
Elevated levels may indicate the presence of conditions such as Paget's disease or certain cancers affecting bone metabolism, leading to abnormal bone growth or remodeling.
Low
Low levels may be associated with osteoporosis or malnutrition, increasing the risk of fractures and resulting in weakened, brittle bones.
Symptoms
High
May include fatigue, headaches, and bone pain, often without visible changes.
Low
Can include dizziness, weakness, frequent bone fractures, and poor posture.
