What You Need to Know About Osteoporosis
Osteoporosis is a condition in which the bones become less dense and more likely to fracture. It has been called a childhood disease with old age consequences because building healthy bones in youth helps prevent osteoporosis and fractures later in life. However, it is never too late to adopt new habits for healthy bones.
The Breast Cancer Link
Women
who have had breast cancer treatment
may be at increased risk for osteoporosis
and fracture for several reasons. First,
estrogen has a protective effect on bone,
and reduced levels of the hormone trigger
bone loss. Because of chemotherapy
or surgery, many breast cancer survivors
experience a loss of ovarian function
and, consequently, a drop in estrogen
levels. Women who were premenopausal
before their cancer treatment
tend to go through menopause (a known
osteoporosis risk factor) earlier than
those who have not had breast cancer.
Studies suggest that chemotherapy also may have a direct negative effect on bone. In addition, the breast cancer itself may stimulate the production of osteoclasts, the cells that break down bone.
Show your bones some love. Fortify your diet with calcium.
Osteoporosis Management
Several
strategies can reduce one’s risk for
osteoporosis or lessen the effects of the
disease in women who have already
been diagnosed.
Nutrition
A well-balanced diet rich
in calcium and vitamin D is important.
Good sources of calcium include low-fat
dairy products; dark green, leafy vegetables;
and calcium-fortified foods and
beverages. Supplements can help ensure
that the calcium requirement is met
each day. The Institute of Medicine
recommends a daily calcium intake of
1,000 mg for men and women, increasing
to 1,200 mg for those age 50 and older.
Vitamin D plays an important role in calcium absorption and bone health. Food sources of vitamin D include egg yolks, saltwater fish, and liver. Many people obtain enough vitamin D by getting about 15 minutes of sunlight each day; others may need vitamin D supplements to achieve the recommended intake of 400 to 600 IU each day.
Exercise
Like muscle, bone is living
tissue that responds to exercise by becoming
stronger. The best activity for
your bones is weight-bearing exercise
that forces you to work against gravity.
Some examples include walking, climbing
stairs, weight training, and dancing.
Regular exercise may help prevent
bone loss and will provide many other
health benefits.
Healthy Lifestyle
Smoking is bad
for bones. Women who smoke tend to
go through menopause earlier, resulting
in earlier reduction in levels of the
bone-preserving hormone estrogen and
triggering earlier bone loss. In addition,
smokers may absorb less calcium from
their diets. Evidence also suggests that
alcohol can have a negative effect on
bone health. Those who drink heavily
are more prone to bone loss and fracture.
Bone Density Test
A bone mineral
density test measures bone density in
various parts of the body. This test can
detect osteoporosis before a fracture
occurs and can predict one’s chances of
fracturing in the future. The test can help
determine whether medication should
be considered. Ask your doctor whether
you might be a candidate for a bone
density test.
Medication
There is no cure for osteoporosis.
However, medications are
available to prevent and treat this disease.
