As people get older, their bones can become thin and lose
mass. This can lead to a very common and serious disease
called osteoporosis. Over time, the disease causes bones to
weaken and break easily.
“Millions of Americans have osteoporosis,” said Christine
Albrecht, a family physician with Lakewood Health System in
Staples, Minnesota. “If not prevented or treated, fractures
of the hip, spine, and wrist commonly occur.”
According to the National
Institute of Health, more than 1.5 million people each year
in the United States suffer an osteoporosis-related
fracture. Dr. Albrecht says that patients who suffer a hip fracture almost always require a major surgery
and encounter a prolonged recovery period. Many people
never walk independently after a breaking their hip.
Statistics show more than one in five will die within a year
after the fracture and the same number end up in a nursing
home. Patients who fracture their spine experience severe
pain and even loss of height.
Although women are four times more likely to develop
osteoporosis than men, the disease is not limited to that
gender. “For many years,
osteoporosis was thought of as a women’s disease, but that’s
definitely not true,” said Dr. Albrecht. “As our population
continues to grow older, we are seeing many more men with
osteoporosis and unfortunately men who suffer an
osteoporosis-related fracture are twice as likely to die
from it than women.”
Osteoporosis
is often called the “silent disease” because bone loss
occurs without any symptoms. The best way to determine your
bone health is to have a screening using a dual-energy x-ray
absorptiometry, or DXA. It is a painless type of x-ray that
looks at both hip and spine bone density.
A DXA scan report will show
normal bone health, osteopenia, or osteoporosis. Osteopenia
means that bones are becoming weak, but are not fragile
enough to be considered osteoporosis.
Screening
should take place at age 65 for otherwise healthy women.
According to the National Osteoporosis Foundation (NOF), men
age 70 and older should also have their bone mineral density
tested. Patients who have certain risk factors should talk
to their family physician about being screened earlier.
Those risk factors include being thin or small-
boned, being of the Caucasian or
Asian race, those who smoke cigarettes, those with a
low dietary calcium intake, women who experience early
menopause, those have used steroids for a long period, those
who have lost height or had previous low trauma fractures.
While there is no cure for osteoporosis, the good news is
that the disease is largely preventable.
To do this, bone health
needs to be maximized by getting enough regular weight
bearing exercise, by quitting smoking, and by getting
adequate amounts of calcium and vitamin D.
Calcium
Getting the
daily recommended amount of calcium, whether through diet,
supplements, or combination, is essential to maintaining
bone strength and can play a vital role in preventing
osteoporosis-related fractures. According to
NOF recommendations, adults under age 50 need 1,000 mg of
calcium daily, and adults age 50 and over need 1,200 mg of
calcium daily.
Vitamin
D
Vitamin D plays a major role in calcium absorption
and bone health. Adults under age 50 need 400-800 IU of
vitamin D daily, and adults age 50 and older need
800 – 1,000 IU of vitamin D daily. Vitamin D can
also be obtained from fortified milk, egg yolks, saltwater
fish, liver and supplements. It can also be made through
skin with sunlight exposure; however, the sun is not strong
enough many months out of the year in Minnesota to make
vitamin D.
“It is still
very important for a person who has been diagnosed with
osteoporosis to get enough exercise, calcium and Vitamin D
to prevent the disease from worsening,” Dr. Albrecht said.
“There are several treatments available now, including oral
IV and injectable medication. A patient should talk with
his or her family physician to find the best treatment
plan.”
