The timing for bone mineral density (BMD) testing depends on various factors, including your age, gender, medical history, and risk factors for osteoporosis. In general, it is recommended to discuss BMD testing with a healthcare professional if you are a postmenopausal woman, have a history of fractures, or have specific medical conditions or lifestyle factors that can affect bone health. Additionally, individuals on long-term medications known to impact bone density or those with other risk factors may also need BMD testing. Your healthcare professional can evaluate your individual circumstances and provide guidance on when to undergo BMD testing. It's important to remember that early detection of osteoporosis or low BMD can help initiate timely interventions and prevent further bone loss or fractures.
