Osteoporosis is a systemic metabolic disorder characterized by damage to the fibrous structure of bone tissue, thinning of the bone cortex, reduction in the number of bone trabeculae, increased bone fragility and increased risk of fracture. Currently, 1 in 14 people in China suffers from osteoporosis to varying degrees, with a prevalence of 21% in people aged 50-60 years, 58% in people aged 60-70 years, and 100% in people aged 70-80 years. With the increasing aging of the population, osteoporosis has become a serious social and public health problem, which affects most postmenopausal women and the elderly, causing great suffering to patients and a heavy economic burden to families and society. The main symptoms of osteoporosis: 1, pain: is the most important complaint of osteoporosis, mainly low back pain, accounting for 70%-80% of patients with pain. The pain spreads along the spine to both sides, intensifies when standing and sitting for a long time, and worsens when bending. It also manifests as generalized skeletal pain or pain in hip, knee and wrist joints. 2.Shortening of body length and hunchback are important features of osteoporosis: they mostly occur after pain and are the result of chronic accumulative deformation and compression fracture of the vertebrae of the spine. 3.Fracture: it is the most common and serious complication of osteoporosis. Many patients have insignificant preexisting pain symptoms and come to the clinic with a nonviolent fracture as the first manifestation. Prevention of osteoporosis: 1. Sufficient calcium should be consumed: generally not less than 850 mg daily; if osteoporosis has occurred, it should be not less than 1000-2000 mg daily. food milk, shrimp, soy products, etc. are rich in calcium. Calcium tablets can be supplemented appropriately. 2, the diet should be rich in protein and vitamin C: high protein diet can significantly increase the absorption of calcium, if the lack of protein in the diet, poor bone organic matter generation; if the lack of vitamin C will affect the formation of bone matrix. Daily supply of high-quality protein 60 -70 g, vitamin C 300mg or more, these components are mainly from poultry eggs, fish, shrimp, milk, soybean products and vegetables, fruits to obtain. 3, appropriate exercise: muscle strength and joint function interact, muscle strength and muscle quantity and quality, muscle strength and bone mass also have a connection, increase muscle strength can prevent falls. The contraction of the random muscle and the stimulation of the body’s own weight on the bone after exercise directly promote the activity of osteoblasts, which is conducive to delaying or limiting the development of osteoporosis. Individuals should choose the appropriate exercise according to their actual situation. 4, daily care: increase sunlight and outdoor activities, living room facing south. Change bad habits, no smoking and alcohol, no coffee and strong tea, carbonated drinks.
