Osteoporosis is a condition in which bone density decreases, making bones more fragile and prone to fractures. Early detection aims to identify abnormal bone loss at the earliest possible stage – ideally before any fracture occurs. Since osteoporosis often develops silently over many years without noticeable symptoms, targeted screening is especially important.
Osteoporosis is frequently diagnosed only after a fracture – such as a vertebral or hip fracture – has already occurred. These fractures can have serious consequences, including chronic pain, loss of mobility, and increased mortality. Early diagnosis enables timely interventions to prevent fractures and slow down bone loss.
Certain groups are at higher risk for developing osteoporosis and should be screened early:
The most important diagnostic tool for early detection is Dual-Energy X-ray Absorptiometry (DXA or DEXA). This technique uses a low dose of X-ray radiation to measure bone mineral density at the lumbar spine and hip. The result is expressed as a T-score:
The FRAX tool (Fracture Risk Assessment Tool) developed by the WHO calculates an individual's 10-year risk of a major osteoporotic fracture based on risk factors such as age, sex, body mass index, and bone density. It helps clinicians determine whether treatment is necessary.
Supplementary blood and urine tests can be performed to rule out secondary causes of osteoporosis. These typically include measurements of calcium, vitamin D, phosphate, parathyroid hormone, and bone turnover markers.
X-rays of the spine can reveal existing vertebral fractures, which often occur without pain and may go unnoticed. These findings are an important indicator of advanced osteoporosis.
The International Osteoporosis Foundation (IOF) and national guidelines recommend bone density measurement particularly for:
In many countries, DXA scans are covered by health insurance when there is a medical indication.
If screening results are abnormal, the treating physician will provide individual counseling. Depending on the severity of osteoporosis, lifestyle changes (e.g., increased physical activity, calcium-rich diet, vitamin D supplementation) and/or pharmacological therapies (e.g., bisphosphonates, denosumab) are recommended to reduce fracture risk.
