Bone Density Tests Risk Detectors For Osteoporosis
Bone density tests allow you
to know whether you are at risk of developing osteoporosis
before anything bad begins to happen. Years ago, the
only time osteoporosis could be detected was after you broke a
bone. By then, however, your bones might already be quite
weak. Today bone density tests,
which are also called densitometry or DEXA scans, can determine
if you have osteoporosis or are at risk of osteoporosis before
you break any bones.
Bone density tests use special X-rays to measure the grams
of calcium and other bone minerals packed into a given segment
of bone. It is a pretty accurate risk predictor. The results
from bone density tests can let you know how you compare as far
as bone mass with other people of your age, gender, and other
similar characteristics.
When your mineral content is high, your bones are dense.
Dense bones are strong and less likely to break. Physicians use
bone density tests to determine if you have or are at risk of
developing osteoporosis.
You should know that bone density tests are not the same as
bone scans. Bone scans are used to detect fractures, cancer,
infections and other abnormalities in the bones. They require
an injection beforehand.
It is generally recommended that you get a bone density scan
if you are over 65 or if you are 60 or over with symptoms
consistent with osteoporosis. Generally, bone density tests are
taken at least two years apart in order to accurately measure
change.
Your bones become weaker as your age. Bone mass is maximized
at age 25 and decreases all the time thereafter.
Whites and Asians are most at risk of developing
osteoporosis. Women are four times more likely to develop
osteoporosis, and should therefore seriously consider bone
density tests if their doctor prescribes them.
If your doctor recommends the test, ask whether your
insurance covers them. Unfortunately, not all insurance
policies cover bone density tests and they can be quite
expensive.
On their own, bone density tests can tell you about your
bone mass, but they can not tell you why you have low bone
density. For that, you need a complete medical history and a
physical.
Bone density tests are usually done on the bones which tend
to break because of osteoporosis including the lumbar
vertebrae, which are in the lower region of your spine, the
narrow neck of your femur bone adjoining the hip, and the bones
of your wrist and forearm.
The bone density tests equipment includes large machines which
you can lie down on as well as smaller, portable machines that
measure bone density on the periphery of your skeleton, such as
in your finger, wrist or heel. The portable devices can
sometimes be used in a drug store without having to go to a
doctor’s office.
You will receive a T-Score which tells you how you compare to a
young adult of your gender. A 0 would indicate that you have
the bones of a 30 year old. Anything above -1 is considered
fine. Between -1 and -2.5 and you are considered to have
pre-osteoporosis or osteopenia, and below -2.5 is considered to
be full fledged osteoporosis.
If you are in a risk category, consider getting your bone
density tests right away.
