osteoporosis

Osteoporosis is a systemic bone disease, which is characterized by the decrease of bone mass and the destruction of bone microstructure. It is manifested in the increase of bone fragility, so the risk of fracture is greatly increased. Fracture is easy to occur even in the case of slight trauma or no trauma. Osteoporosis is a chronic disease caused by many factors. Before the occurrence of fracture, there is usually no special clinical manifestation. The disease is more common in women than men, and is common in postmenopausal women and the elderly. With the increase of the elderly population in China, the incidence rate of osteoporosis is on the rise. It is a healthy issue in China and even in the world.
