Osteoporosis is sometimes diagnosed incidentally after an X-ray has been taken for a fracture or an illness. If your health care provider suspects you have osteoporosis, he or she may measure you to check for a loss of height. The vertebrae are often the first bones affected, causing a loss in height of half an inch or more. Your health care provider may also recommend that your bone density be measured.
Diagnostic tools more likely to catch osteoporosis at an early stage include various forms of a technique called absorptiometry, which is specifically designed to measure bone density. A relatively new diagnostic tool known as quantitative computerized tomography is also an accurate method of measuring bone density anywhere in the body, but it uses higher levels of radiation than the other methods. Some facilities are also equipped with specialized ultrasound machines that can detect early signs of osteoporosis.
For years, we've thought we understood osteoporosis: it's a disease in which the bones become more and more fragile as they lose density, usually due to aging, menopause, and other factors like lack of calcium and vitamin D in the diet.
But today, advances in research are shedding new light on osteoporosis, which is predicted to affect as many as half of all Americans over age 50 by the year 2020. From diagnosis to prevention to osteoporosis treatment, new research is turning our old understanding...
Menopausal hormone therapy -- either estrogen alone or a combination of estrogen and progestin -- can prevent and treat osteoporosis. The drug Duavee (estrogen and bazedoxifene) is a type of HRT approved to treat menopause-related hot flashes. Duavee may also prevent osteoporosis in high-risk women who have already tried non-estrogen treatment.
A landmark study called the Women's Health Initiative revealed that hormone therapy increases the risk of breast cancer, heart disease, and stroke in some women. Hormone therapy is known to help preserve bone and prevent fractures, but is not generally recommended at this point for osteoporosis because the risks are thought to outweigh the benefits.
