Osteoporosis
is a debilitating bone condition that affects 25 million Americans and is
particularly common in the elderly. Its impact on health, lifestyle, and
emotional well-being can be far reaching. In fact, some health
professionals feel that osteoporosis is reaching epidemic proportions.
Approximately one in four postmenopausal women will suffer at least one
fracture by the age of 65.
At the same
time, it's important to note that men are vulnerable as well: It strikes
an estimated 10 to 15 percent of men in their 70s.
Q. What is
osteoporosis?
A. When levels of calcium and phosphorus, the minerals essential to bone
formation, are insufficient, bone mass is lost. This causes bones to
become dry and brittle.
Q. Who is at risk?
A. Women are much more likely than men to develop osteoporosis because, as
a group, they have lighter bones and less total calcium. In fact, women
lose bone at a rate three times greater than that of men. Other risk
factors include age, family history, race (women of Northern European
descent are more susceptible, as are Asian women), low calcium and vitamin
D intake, inactive lifestyle, a petite body frame, smoking, and excessive
alcohol use.
Q. What are the symptoms? What should I do if I have symptoms?
A. Sometimes the first sign of osteoporosis is a loss of height or the
beginnings of a humped back caused by a collapse of weakened vertebrae.
However, usually there are no symptoms until a fracture occurs. The first
sign may be sudden pain in the back or hip, or painful swelling of a joint
after a minor fall.
You should see a health professional if any of these symptoms occur, if a
sprain does not improve after four days of home treatment, or if there is
a lot of swelling or bruising after even a minor fall.
Q. Can osteoporosis be prevented?
A. The two major strategies for helping reduce the risk of osteoporosis
are proper nutrition and regular weight-bearing exercise. Men and
pre-menopausal women should consume a minimum of 1,000 mg of calcium per
day. Postmenopausal women should consume 1,500 mg. Excellent sources of
calcium include skim milk, low-fat yogurt, chopped collards, broccoli, and
canned sardines with bones.
The second defense against osteoporosis is daily weight-bearing exercises
that place stress on the major joints, thus encouraging bone growth.
Excellent exercises include walking, jogging, aerobic dance, and tennis.
Recent studies suggest that weight training also may help maintain bone
density.
Q. How is it diagnosed?
A. Diagnosis usually occurs after a fracture when an X-ray reveals
osteoporosis. An X-ray of normal bone shows a very white, harsh image. But
in a bone with too little calcium, this white color is noticeably washed
out. The calcium content of bone (typically in the spine and hip) can be
measured by dual-energy X-ray absorptiometry (DEXA), in which the
absorption of low-level radiation is measured and assigned a number based
on the bone's density. This can be done prior to a fracture as well to
determine future fracture risk.
Q. How is it treated?
A. Scientists are not sure whether you can slow or prevent further
degeneration. But treatment options can minimize the negative effects of
osteoporosis.
First, maintaining a balanced diet (with adequate levels of calcium) and
exercising regularly may provide benefit to those already suffering from
osteoporosis.
Hormone replacement therapy (HRT) has been shown to be an effective
treatment for preserving bone density in women. However, there's evidence
that HRT may increase breast cancer risk, as well as complications such as
breast tenderness, breakthrough bleeding, and bloating. Talk to your
doctor about the benefits and risks of HRT.
Another treatment approach is the use of prescription medications to slow
the rate of bone loss in women who have significant osteoporosis.
Alendronate (Fosamax) has been shown to increase bone density and prevent
fractures. Calcitonin (Calcimar and Miacalcin) has been shown to reduce
bone loss.
Hip replacement surgery is a common treatment for degenerated hips. With
hip replacement, complications are markedly reduced and independence
improved.
Finally, because osteoporosis can be painful and can rob people of their
independence and self-esteem, victims can become isolated and depressed.
Be alert for the signs and symptoms of depression.
