Simply put, the mechanism of osteoporosis is that the degree of bone destruction exceeds the degree of bone regeneration, the human body through a variety of complex mechanisms to regulate the balance of these two processes, due to various reasons leading to the disruption of this balance, which also leads to the occurrence of osteoporosis Risk factors leading to osteoporosis: 1, age, people over 65 years old. This is a very important factor, with the growth of age, the new bone capacity decreases, the degree of destruction of bones is greater than the degree of new, and gradually there will be a reduction in bone mass, and even osteoporosis, age we can not reverse, but through early prevention when young and avoid some bad habits can be very good to delay the occurrence of osteoporotic fractures. 2, genetic, Caucasians are more susceptible than yellow people, yellow people are more susceptible than black people, and those with a family history of osteoporosis are susceptible. It is not a good idea to feel as yellow people, at least better than those white people in Europe and the United States. 3, diet, long-term low calcium high sodium diet (high salt diet), lack of nutrition. Long-term low-calcium diet will of course lead to a reduction in calcium in the body, which is not conducive to the new bone, high-salt diet and a large amount of sodium, will competitively inhibit the absorption of calcium (the mechanism is complex, not the loss of brain cells) 4, thin, low body mass index people with a high incidence of osteoporosis. 5, post-menopausal women or premature amenorrhea and women with declining estrogen due to ovariectomy. In our professional words, estrogen deficiency leads to osteoclast proliferation and differentiation, and osteoclast function is active, while osteoclast apoptosis is inhibited, which causes the rate of bone resorption to exceed the rate of bone formation, resulting in a proportional decrease in organic and inorganic bone material. 6, people with alcohol, heavy smoking, long-term coffee, strong tea, staying up late and other habits. These habits can lead to a decrease in osteoblast activity, so that the rate of bone resorption exceeds the rate of bone formation, which in turn will be prone to osteoporosis. We look at this article is not feeling creepy ah, is not feeling for no reason are shot? We can responsibly say that this is not alarmist, bad habits have a great impact on the occurrence of osteoporosis, or please improve the appropriate bad habits to avoid the tragedy of “youth buried disaster, old age suffer. 7, drugs, long-term use of corticosteroids, barbiturates, dalantin, heparin, etc.. This is the side effects of drugs, the mechanism is also very complex, so I will not say more. 8, disease, endocrine diseases, nutritional and metabolic diseases, renal insufficiency, rheumatoid arthritis, severe liver disease, etc. Osteoporosis is a systemic disease, it involves a number of disciplines, not only orthopedic diseases, many internal diseases will be combined with osteoporosis. 9, weightlessness, such as astronauts. This has little to do with us, and the space heroes will not worry about this. 10, lack of exercise, long-term indoor work lack of sunlight, such as long-term bedridden people. This is disuse osteoporosis, life lies in sports, despite the high PM2.5, but keep regular physical exercise is not only to prevent osteoporosis, all systems of the body have great benefits, here will not be verbose. The summary of the 10 risk factors of osteoporosis is also to let readers clearly understand the causes of osteoporosis, and can effectively prevent, the prevention of osteoporosis is the main work is to prevent, and then is the treatment.
