NOF's Five Steps to Bone Health and Osteoporosis Prevention:

• Get your daily recommended amounts of calcium and vitamin D
• Engage in regular weight-bearing exercise
• Avoid smoking and excessive alcohol
• Talk to your healthcare provider about bone health
• Have a bone density test and take medication when appropriate
  

Calcium

Calcium is needed for the heart, muscles and nerves to function properly and for blood to clot. Inadequate calcium is thought to contribute to the development of osteoporosis. National nutrition surveys have shown that many women and young girls consume less than half the amount of calcium recommended to grow and maintain healthy bones.

Depending on your age, an appropriate calcium intake falls between 1000 and 1300 mg a day. If you have difficulty getting enough calcium from the foods you eat, you may take a calcium supplement to make up the difference.

Vitamin D

Vitamin D is needed for the body to absorb calcium. Without enough vitamin D, you will be unable to absorb calcium from the foods you eat, and your body will have to take calcium from your bones. Vitamin D comes from two sources: through the skin following direct exposure to sunlight and from the diet. Experts recommend a daily intake between 400 and 800 IU per day, which also can be obtained from fortified dairy products, egg yolks, saltwater fish and liver.

Exercise

Exercise is also important to good bone health. If you exercise regularly in childhood and adolescence, you are more likely to reach your peak bone density than those who are inactive. The best exercise for your bones is weight-bearing exercise such as walking, dancing, jogging, stair-climbing, racquet sports and hiking. If you have been sedentary most of your adult life, be sure to check with your healthcare provider before beginning any exercise program.

Medications for Prevention and Treatment

Although there is no cure for osteoporosis, currently bisphosphonates (alendronate and risedronate), calcitonin, estrogens, parathyroid hormone and raloxifene are approved by the US Food and Drug Administration (FDA) for the prevention and/or treatment of osteoporosis.

Bone Mineral Density Tests

A Bone Mineral Density test (BMD) is the only way to diagnose osteoporosis and determine your risk for future fracture. Since osteoporosis can develop undetected for decades until a fracture occurs, early diagnosis is important.

A BMD measures the density of your bones (bone mass) and is necessary to determine whether you need medication to help maintain your bone mass, prevent further bone loss and reduce fracture risk. A bone mineral density (BMD) test is a special type of test that is accurate, painless and noninvasive.
