Osteoporosis is progressive bone loss that makes bones weaker and more likely to break. It usually has no symptoms until a fracture occurs, so identifying and treating those at risk is central to preventing fractures.
Osteoporosis means the bones become thinner and weaker and break more easily. It develops silently over years, and often the first sign is a fracture from a minor injury — commonly of the wrist, spine or hip. Because it is symptomless until then, the goal is to identify and treat those at risk before a fracture occurs.
Fracture-risk assessment is a core part of preventive practice. A DXA scan measures bone density and is Medicare-rebated in defined situations (for example, age 70 and over, after a minimal-trauma fracture, or with certain conditions or medications). Risk calculators such as FRAX or Garvan help guide decisions, and a fracture from minimal trauma after 50 itself warrants assessment and usually treatment.
Management combines lifestyle and medical measures: adequate dietary calcium and vitamin D, weight-bearing and resistance exercise, stopping smoking, limiting alcohol, and falls prevention, alongside PBS-subsidised medicines — such as bisphosphonates, denosumab and anabolic agents — for those at higher risk. Treatment is individualised, and menopausal hormone therapy is an option for some women. Ongoing review with your GP ties this together.
