Although osteoporosis is more common in older women, men also can
develop the condition. Regardless of your sex or age, your doctor may
recommend a bone density test if you've:
- Lost height. People who have lost at least 1.6
inches (4 centimeters) in height may have experienced compression
fractures in their spines. Osteoporosis is one of the main causes of
compression fractures.
- Fractured a bone. Fragility fractures occur when a
bone becomes so fragile that it breaks much more easily than expected.
Fragility fractures can sometimes be caused by a strong cough or sneeze.
- Taken certain drugs. Long-term use of steroid
medications, such as prednisone, interferes with the bone-rebuilding
process — which can lead to osteoporosis.
- Received a transplant. People who have received an
organ or bone marrow transplant are at higher risk of osteoporosis,
partly because anti-rejection drugs also interfere with the
bone-rebuilding process.
- Experienced a drop in hormone levels. In addition
to the natural drop in hormones that occurs after menopause, women may
also experience a drop in estrogen during certain cancer treatments.
Some treatments for prostate cancer reduce testosterone levels in men.
Lowered hormone levels weaken bone.
