In the old days, before doctors diagnosed

Diseases of the skeletal system, osteoporosis, also known as porous bone >> << affects both men and women, and all demographic groups. When bones lose mass and mineral density, they become more susceptible to

cracks and breaks. This is one reason that osteoporosis is also known as

asymptomatic disease, because he did not show the common or

verteberal a fracture occurs. Osteoporosis is a condition of low bone density. Think of it as thin bones >>. Osteoporosis << affects 10 million people in the United States

mostly women. Other 34000000

Americans are. It is believed that one in three women aged >> << 50 will experience fractures due to low bone density. Think of bone blood vessels growing tissue with external >> << layer of bark or dense bone, which is wrapped around trabekulyarnoy >> << or spongy bone. Sponge, a healthy interior of bones like image

porous sponges, and osteoporosis, effectively holes in the

growth of sponges and become more numerous, thus >> << general weakening of the internal structure instead of foreign

which contains hydroxyapatite in terms of minerals. Roughly

The general chemical formula [Ca3 (P) 4) 2] 3. Ca (OH) 2. In this laboratory mineral >> << may be terminated in calcium phosphate, calcium fluoride, calcium carbonate,

constantly created and destroyed, even in adults. If >> << homeostasis between creation and destruction comes disorder and bone fossil

People's understanding of the bones of the body just as the internal structure of the forest >> << no other function is wrong. Bone living tissue, constantly

. Advanced cases of osteoporosis can disable person and seriously limit the mobility of

). They are active mainly at the surface of spongy bone (called

spongy tissue) and in cortical bone. Osteoblasts are cells that create the fabric

Bonnie (create minerals). Resorption / removal process

rather than setting new bone osteoblasts, so >> << increase in bone formation and reconstruction of the common causes of bone loss,

when it occurs in adults. Glucocorticoid drugs and other physiological

conditions such as chronic inflammatory disease and thyroid problems

may contribute to the risk of fractures. In the past people thought that the lack of estrogen caused by osteoporosis. People thought this because most patients were women who went from osteoporosis after menopause >> << and that estrogen has an effect on bone formation activity of osteoblasts

. However, similar studies have shown that lowering estrogen levels

is not the main cause of osteoporosis. Estrogen acts through two receptors

name age and ERb. Osteoblasts express ERb, but not

clear that ERb agoinsts promote bone density. Estrogen supplements were given to post menopausal women to reduce the risk of osteoporosis

and for other reasons. This practice is used much less

out, because the benefits of estrogen seem to outweigh the risks. Another old theory that calcium deficiency caused by osteoporosis. Older people

consume less calcium and vitamin D, than young people, and >> << digestive system does not absorb these nutrients as well. A cumulative effect >> << not enough calcium and vitamin D for many years leads to osteoporosis. The body produces parathyroid hormone (PTH) which regulates the levels of calcium and phosphate

. Hyperparathyroidism occurs in many elderly and

epidemiological studies correlated this condition with osteoporosis >> frequency. Tests << with people giving supplements of calcium and vitamin D leads

to increase serum levels of both, and even increase bone mass, but it >> << It is not clear whether these supplements reduces the rate of bone fractures. Synthetic hormone parathyroid glands used as a treatment of osteoporosis. When scientists found that calcitonin inhibits the action of osteoclasts

(about 1970), people thought that the natural disadvantage of calcitonin in >> << body may be the cause of osteoporosis and calcitonin supplements can treat osteoporosis

. Further investigation showed that there is no shortage >> << calcitonin in osteoporosis patients, and although the additives found

use as a therapy, it has never been as effective on a large scale as bisphosphonates

drugs. In the old days, before doctors diagnosed osteoporosis only after fractures

(often small fractures seen only in X-ray). While the disease is often suspected

often hard for women who have lost height, only fractures could

give a final diagnosis. ON allows doctors find and treat osteoporosis and osteopenia >> << before fractures occur. Indeed, the medical profession

definition of osteoporosis is currently based on bone density and no fractures. The third cause of osteoporosis broken bone formation, and it only

recently that modern medicine was able to attack this issue directly. Although it is known from animal studies, giving injections of the hormone parathenoid >> << can increase bone mass only in the last decade, that s >> << development and use of teriparatide, which is was effective

therapy in humans. Teriparatide is a synthetic hormone parathenoid. Strontium ranelate

is a double agent of the bones (DABA), used in the UK and

other countries but not approved for use in the United States. The main risk factors are age (formerly 50) and women. People with >> << small body sizes tend to get osteoporosis at a higher rate. Atrophy, such as >>, << when a person is disabled because of spinal cord injury or stroke,

associated with osteoporosis, some medications, including chemotherapy

cancer increases the risk, and there were cases of osteoporosis >> << associated with celiac disease when the patient does not absorb enough nutrients. Fractures are more common in people with diabetes than without diabetes, but it seems as osteoporosis and diabetes concomitant rather than a reason other hand, at least a second type of diabetes. Type I may contribute to the development of osteoporosis, but evidence is not strength. Lifestyle methods such as smoking, alcohol, and

lack of exercise can increase the risk of osteoporosis. Hormone violation

(including hyperthyroidism and low levels of sex hormones) may increase the risk. Very rare hormone problem hyperparathyroidism, where parathyroid gland

marrow produces too many hormones. Sources of lasix fluid pill material on this page:,,,
