Prevent Bone Loss

Has your grandmother fallen and broken a bone? Have you noticed that your mother’s back is no longer straight when she walks?
For generations, women have dealt with osteoporosis—a condition in which the bones become less dense and are more likely to fracture. It’s often called the “silent disease” because you may not notice any changes until you break a bone, typically in the hip, spine or wrist, or you discover that you’re not as tall as you used to be.
But today’s women no longer have to accept osteoporosis as a fact of life as they get older. There are ways to prevent weakened bones in later life, slow your rate of bone loss and rebuild bones to prevent fractures.

Risk Factors
To keep bones strong, the body is always breaking down old bone and replacing it with new tissue. As we age, more bone is broken down than is replaced and the risk of osteoporosis increases, especially for women around the time of menopause.
Several risk factors increase your chances of developing osteoporosis, including:
• a thin, small-boned frame
• previous fracture or family history of bone fractures
• estrogen deficiency from early menopause (before age 45)
• advanced age
• a diet low in calcium
• Caucasian, Asian or Hispanic ancestry
• cigarette smoking
• excessive use of alcohol
• prolonged use of certain medications to treat such diseases as lupus, asthma, arthritis and cancer.
Getting enough calcium throughout life helps to build and keep strong bones. People over age 50 should get 1200 mg of calcium daily. To do this, eat calcium-rich foods, such as low-fat dairy foods, canned fish with soft bones like salmon, dark green leafy vegetables, and calcium-fortified foods like orange juice, breads and cereals.
To get enough calcium, you may need to take a daily calcium supplement with vitamin D. When I check blood levels, many of my patients have very low levels of vitamin D. Your body uses vitamin D to absorb calcium. Being in the sun for 20 minutes every day helps most people’s bodies make enough vitamin D. You can also get vitamin D from eggs, fatty fish, and cereal and milk fortified with vitamin D.
Exercise makes bones and muscles stronger and helps prevent bone loss. Weight-bearing exercises, such as walking, jogging, playing tennis and dancing three to four times a week, are best for preventing osteoporosis. Strengthening and balance exercises may help you avoid falls and lessen your chance of breaking a bone.
Tests and Treatment
Talk to your doctor if you have a family history of osteoporosis or other factors that may increase your risk for the disease. A safe, painless, bone mineral density test known as a dual- energy x-ray absorptiometry, or DEXA scan can determine your risk for osteoporosis.
In addition to exercise and calcium supplements, your healthcare provider may prescribe medications that you take once a week or month to help rebuild the strength of your bones.
