Osteoporosis




What Is Osteoporosis?

Osteoporosis is a disease in which the bones become weak and are more likely to break. People with osteoporosis most often break bones in the hip, spine, and wrist.

Who Gets Osteoporosis?

In the United States, 10 million people have osteoporosis. Millions more have low bone mass (called osteopenia), placing them at risk for osteoporosis and broken bones. Osteoporosis can strike at any age, but it is most common in older women. Eighty percent of the people in the United States with osteoporosis are women. One out of every two women and one in four men over age 50 will break a bone in their lifetime due to osteoporosis.



What Causes Osteoporosis?

Many risk factors can lead to bone loss and osteoporosis. Some of these things you cannot change and others you can.
  • Risk factors you cannot change include:
  • Gender
    Women get osteoporosis more often than men.
  • Age
    The older you are, the greater your risk of osteoporosis.
  • Body size
    Small, thin women are at greater risk.
  • Ethnicity
    White and Asian women are at highest risk. Black and Hispanic women have a lower risk.
  • Family history
    Osteoporosis tends to run in families. If a family member has osteoporosis or breaks a bone, there is a greater chance that you will too.
  • Other risk factors are:
  • Sex hormones
    Low estrogen levels due to missing menstrual periods or to menopause can cause osteoporosis in women. Low testosterone levels can bring on osteoporosis in men.
  • Anorexia nervosa
    This eating disorder can lead to osteoporosis.
  • Calcium and vitamin D intake
    A diet low in calcium and vitamin D makes you more prone to bone loss.
  • Medication use
    Some medicines increase the risk of osteoporosis.
  • Activity level
    Lack of exercise or long-term bed rest can cause weak bones.
  • Smoking
    Cigarettes are bad for bones, heart, and lungs.
  • Drinking alcohol
    Too much alcohol can cause bone loss and broken bones.
Can Osteoporosis Be Prevented?

There are many steps you can take to keep your bones healthy. To keep your bones strong and slow down bone loss, you can:
  • Eat a diet rich in calcium and vitamin D.
  • Exercise.
  • Not drink in excess or smoke.
Nutrition

A diet with enough calcium and vitamin D helps make your bones strong. Many people get less than half the calcium they need. Good sources of calcium are:
  • Low-fat milk, yogurt, and cheese.
  • Foods with added calcium such as orange juice, cereals, and breads.
Vitamin D is needed for strong bones. Your body makes vitamin D in the skin when you are out in the sun. Some people get all the vitamin D they need from sunlight. Others need to take vitamin D pills. The chart on this page shows the amount of calcium and vitamin D you should get each day.

Age Calcium Vitamin D
0 to 6 months 210 mg 200 IU
7 to 12 months 270 mg 200 IU
1 to 3 years 500 mg 200 IU
4 to 8 years 800 mg 200 IU
9 to 18 years 1,300 mg 200 IU
19 to 50 years 1,000 mg 200 IU
51 to 70 years 1,200 mg 400 IU
Over 70 years 1,200 mg 600 IU


Exercise

Exercise helps your bones grow stronger. To increase bone strength, you can:
  • Walk
  • Hike
  • Jog
  • Climb stairs
  • Lift weights
  • Play tennis
  • Dance.
Healthy Lifestyle

Smoking is bad for bones as well as the heart and lungs. Also, people who drink a lot of alcohol are more prone to bone loss and broken bones due to poor diet and risk of falling.



What Are the Symptoms of Osteoporosis?

Osteoporosis is called the “silent disease” because bone is lost with no signs. You may not know that you have osteoporosis until a strain, bump, or fall causes a bone to break.

How Is Osteoporosis Treated?

Treatment for osteoporosis includes:
  • A balanced diet rich in calcium and vitamin D.
  • An exercise plan.
  • A healthy lifestyle.
  • Medications, if needed.
