DEXA Scan
What is a DEXA Scan?
Bone Densitometry, also known as DEXA/DXA, is the most accurate and widely used method for diagnosing osteoporosis. DEXA uses two different X‑ray energy levels to measure bone mineral density in the spine, hip and wrist to assess bone loss. The test takes only a short time and involves very low radiation, so people aged 45 and over can safely undergo regular screening.
Relationship between bone density and age:
Osteoporosis is often called a "silent disease" because it usually causes no obvious symptoms in its early stages, and patients often only discover they have it after a fracture occurs. The condition is more common in older adults because, as people age, osteoblast activity decreases and bone loss accelerates, leading to a gradual decline in bone mineral density.
According to the Department of Health publication "Osteoporosis", the following individuals should consider undergoing a DEXA scan:
-
Advancing age
-
Having a family history of osteoporosis and fracture
-
Being underweight
-
malnutrition
-
Having an unhealthy lifestyle (e.g. Smoking or Excessive alcohol consumption)
-
Disease risk factors include estrogen deficiency in women, endocrine disorders, chronic illnesses, vitamin D deficiency, and a history of intestinal surgery.
-
prolonged corticosteroid use
