Osteoporosis  

The National Institute on Aging (NIA), part of the National Institutes of Health shared that Osteoporosis is a disease that weakens bones to the point where they break easily—most often, bones in the hip, backbone (spine), and wrist. Osteoporosis is called a “silent disease” because you may not notice any changes until a bone breaks. All the while, though, your bones had been losing strength for many years.

Bone is living tissue. To keep bones strong, your body breaks down old bone and replaces it with new bone tissue. Sometime around age 30, bone mass stops increasing, and the goal for bone health is to keep as much bone as possible for as long as you can. As people enter their 40s and 50s, more bone may be broken down than is replaced.

A close look at the inside of bone shows something like a honeycomb. When you have osteoporosis, the spaces in this honeycomb grow larger, and the bone that forms the honeycomb gets smaller. The outer shell of your bones also gets thinner. All of this makes your bones weaker.

Who Has Osteoporosis? Risk Factors and Causes

Although osteoporosis can strike at any age, it is most common among older people, especially older women. Men also have this disease. White and Asian women are most likely to have osteoporosis. Other women at great risk include those who:

• Have a family history of broken bones or osteoporosis
• Have broken a bone after age 50
• Had surgery to remove their ovaries before their periods stopped
• Had early menopause
• Have not gotten enough calcium and/or vitamin D throughout their lives
• Had extended bed rest or were physically inactive
• Smoke (smokers may absorb less calcium from their diets)
• Take certain medications, including medicines for arthritis and asthma and some cancer drugs
• Used certain medicines for a long time
• Have a small body frame

The risk of osteoporosis grows as you get older. At the time of menopause, women may lose bone quickly for several years. After that, the loss slows down but continues. In men, the loss of bone mass is slower. But, by age 65 or 70, men and women are losing bone at the same rate.
