Osteoporosis is a systemic bone disease characterized by a decrease in bone mass and destruction of the microstructure of the bone, manifested by an increased brittleness of the bone and therefore a much higher risk of fracture, even with minor trauma or in the absence of trauma. The disease is commonly seen in postmenopausal women and the elderly. Osteoporosis usually has no specific clinical manifestations before fracture occurs, therefore, prevention is more important than treatment. With the increase of the elderly population in China, the incidence of osteoporosis is on the rise, and osteoporosis in the elderly is a health problem of concern in China and worldwide. The prevention of senile osteoporosis focuses on preventing further bone loss, and to protect the fragile bone, we must start from our daily habits. 1, appropriate sports: moderate exercise is beneficial to muscle and bone health, can improve muscle tone and elasticity, enhance the tolerance of bones, increase the amount of bone bleeding, so that good bone nutrition, delay the aging of bones. The elderly should pay attention to the amount of exercise, too much exercise, too little is not appropriate; and to pay attention to safety, exercise time should be selected in the light of the time. Secondly, to choose a good sports venue, should be familiar with the environment is appropriate, do not choose at the same time there are young people in strenuous activities in the place, so as not to be affected by the collision and cause damage. 2, pay attention to reasonable nutrition: calcium is necessary to maintain the strength of the bones, calcium-rich foods help the balance of calcium metabolism, facilitate the deposition of bone minerals, adequate protein helps the formation of bone matrix. The amount of calcium in the diet of the elderly is often insufficient, which is related to factors such as reduced food intake, poor appetite and reduced digestive function, so pay attention to the intake of calcium-rich foods, such as milk and eggs can provide high-quality protein, but also rich in calcium and phosphorus. Others are green vegetables, beans and soy products, fish and shrimp, seafood plants, shellfish, etc. The intake of various vitamins is also important to prevent and treat osteoporosis. 3, to prevent falls: elderly people’s bones become fragile because of osteoporosis, but as long as they are well protected, like a glass, will not break without crashing to the ground, so preventing falls is an important measure to prevent fractures caused by osteoporosis. 4, prohibit smoking, alcohol: smoking can increase the acidity of the blood to dissolve the bone, drinking too much alcohol, too often will lead to hyperadrenocorticism and cause osteoporosis. 5.Preserve a good state of mind, which helps to strengthen the neural response and balance function, thus reducing the occurrence of fractures. 6.Actively treat some medical diseases that can cause osteoporosis, many endocrine diseases, myeloma, leukemia can cause osteoporosis. 7, careful use of some drugs that can promote osteolysis: such as prednisone, heparin and so on.
