Understanding an abnormal bone density scan

The result is not interpreted in isolation. Your clinician considers age, sex, menopause or hormone history, previous fractures, family history, medicines, medical conditions and fall risk before recommending monitoring, further tests or treatment.

A DEXA scanner uses low-dose X-rays to estimate mineral density, commonly at the hip and spine. The report compares the measurement with reference values and may describe reduced density or osteoporosis. Scanner differences, positioning, arthritis and previous spinal injury can affect individual readings, so trends are most useful when comparable sites and methods are used. Premature ovarian insufficiency can contribute to bone loss because reduced oestrogen affects bone maintenance.

Review the report with a clinician who can assess fracture risk and look for reversible contributors. This may include discussing diet, vitamin intake, hormone changes, thyroid or digestive problems, kidney health, smoking, alcohol and medicines that affect bone. Weight-bearing and resistance activity, adequate nutrition and fall prevention can support bone health when suited to your mobility. If medicine is proposed, ask how to take it, what monitoring is needed and which side effects require advice.

Reduced bone density itself usually causes no immediate symptoms. Seek urgent assessment after a fall or minor injury if there is severe hip, back or wrist pain, inability to bear weight, a visibly deformed limb, new weakness or numbness, or loss of bladder or bowel control. New persistent back pain or noticeable height loss should also be assessed because a spinal fracture can occur without a dramatic accident.

Ask which bones were measured, whether technical factors influenced the reading, and how the result changes your personal fracture assessment. Clarify whether blood tests, treatment, exercise guidance, fall-prevention support or a later repeat scan is recommended.
