A 2002 report from a large clinical trial called the Women's Health Initiative helped verify HRT's positive effects in preventing osteoporosis in postmenopausal women.
A. you see, our bones are a giant storage of calcium. our body needs a very steady concentration of calcium, if it'll be low the body will take it form your bones. if there's too much- it'll either build bones (but only if he'll think he needs too- that is where sport get in the picture)or you'll urinate it.
La mayorÃa de los aparatos usados de modo a la DXA son aparatos centrales, que se utilizan de modo a medir la densidad ósea en la cadera y en la columna.
As mentioned above, age is a primary risk factor of osteoporosis. Unless proper prevention or treatment efforts are made, your body’s increasing breakdown of bone can lead to weakened bones and osteoporosis.
A osteoporose é mais comum em mulheres após a menopausa e em homens e mulheres utilizando mais por 65 anos. Contudo, Há fatores por perigo de que aumentam as chances da pessoa desenvolver a doença.
Osteoporosis affects 20 million U.S. residents, about 80% of them women, and costs U.S. society as much as $13.oito billion annually. About 1.3 million fractures attributable to osteoporosis occur each year in people aged 45 and older, and this condition is responsible for 50% of fractures occurring in women older than age 50. Although all bones are affected, compression fractures of the vertebrae and traumatic fractures of the wrist and femoral neck are most common. Loss of body height and development of kyphosis may be the only signs of vertebral collapse. Fractures in the elderly often lead to loss of mobility and independence, social alienation, fear of further falls and fractures, and depression. After hip fracture, most elderly patients fail to recover normal activity, and mortality within 1 year approaches 20%. Osteoporosis occurs when bone resorption outpaces bone formation. Underlying mechanisms are complex and probably diverse. Bone constantly undergoes cycles of resorption and remodeling to maintain the concentration of calcium and phosphate in the extracellular fluid. When serum calcium concentration drops, increased secretion of parathyroid hormone stimulates bone resorption by osteoclasts to restore serum calcium levels to normal. Bone mass declines with age and is influenced by sex, race, menopause, and weight-for-height. Dietary intake of calcium and vitamin D as well as intestinal and renal function affect calcium and phosphate homeostasis. The risk of osteoporosis is highest in postmenopausal women. Asian or white race, underweight, dietary calcium deficiency, sedentary lifestyle, alcohol use, and cigarette smoking appear to be independent risk factors. The decline of vitamin D3 level with aging results in calcium malabsorption, which, in turn, stimulates bone resorption. Estrogen deficiency exacerbates this problem by increasing the sensitivity of bone to resorbing agents. Female athletes who become amenorrheic because of rigorous exercise and dietary restriction or eating disorders are at risk of osteoporosis. The formation and resorption of bone are also influenced by external physical factors such as body weight and exercise. Immobilization and prolonged bed rest produce rapid bone loss, whereas exercise involving weight-bearing, resistance, and high impact has been shown both to reduce bone loss and to increase bone mass. Risk factors for osteoporosis in men include alcoholism, chronic lung disease, hypogonadism, and rheumatoid arthritis, and other disorders that restrict mobility. Osteoporosis is common in young adults with cystic fibrosis and in people receiving long-term thyroid hormone or glucocorticoid therapy. The diagnosis of primary osteoporosis is established by documentation of reduced bone density after exclusion of known causes of excessive bone loss.
There are many signs of osteoporosis, both large and small. Learn what they are so you can prevent or treat this condition.
Men continue to lose bone at this age, but at a slower rate than women do. However, by the time they reach the ages of 65 to 70, women and men are usually losing bone at the same rate.

Por lo general, la DXA se realiza en las caderas y la zona inferior de la columna vertebral. En los niños y algunos adultos, por lo general, se explora la totalidad del cuerpo. Los dispositivos periféricos que utilizan rayos X o ultrasonido se usan en ocasiones para explorar la masa ósea baja, la mayorÃa por las veces en el antebrazo.

The fractures can cause severe back pain, but sometimes go unnoticed—either way, the vertebrae collapse down on themselves, and the person actually loses height. The hunchback appearance of many elderly women, sometimes called "dowager's" hump or "widow's" hump, is due to this effect of osteoporosis on the vertebrae.
