Tertiary prevention of osteoporosis is also called the ladder prevention method. It is to divide the population that should be included in the prevention of osteoporosis into three prevention stages, and each stage is focused on its characteristics to take preventive measures to achieve the purpose of improving the level of prevention and reducing the cost of prevention. 1, primary prevention: the main population is children and adolescents. The focus of prevention is a reasonable dietary structure, advocating a “balanced diet” and more calcium-rich foods, such as fish, shrimp, kelp, milk and milk products, mixed cereals, beans and soy products and green leafy vegetables. Maintain a good mental state and lifestyle habits, such as not drinking alcohol, not smoking, not drinking strong coffee, not drinking strong tea, adhere to physical exercise, late marriage, late childbirth and lactation period is not too long. The overall goal of the above measures is to keep the body from losing too much calcium and to increase the peak bone density as much as possible, so as to lay a good foundation for the prevention of osteoporosis at different stages of life. 2, secondary prevention: the main population is middle-aged, especially postmenopausal women. The main means of prevention should consider the use of some drugs to prevent osteoporosis, in addition to continuing to maintain a reasonable diet, adequate calcium intake and appropriate physical exercise. Scholars at home and abroad agree that the use of calcium supplements (such as calcium gluconate, calcium carbonate, etc.), calcium regulators (such as vitamin D, calcitriol, etc.), and estrogens (nil estrol, estriol, etc.) can be effective in preventing osteoporosis. At the same time, it is necessary to actively prevent and treat diseases related to osteoporosis, such as diabetes, rheumatoid arthritis, hyperthyroidism, hyperparathyroidism, chronic hepatitis and hepatic steatosis, etc. 3.Tertiary prevention: The main population is middle-aged and elderly people with osteoporosis. The focus of prevention is to promote bone formation (such as the use of vitamin D) and inhibit bone resorption (such as the use of estrogen, calcium, etc.) through drugs; to enhance physical fitness through comprehensive methods, such as appropriate activities, physical therapy, physiotherapy and reasonable diet; to slow down the progress of osteoporosis by adjusting life status, such as improving lifestyle (no strong tea, no strong alcohol, quit smoking), strengthening immune function (treatment of diseases related to osteoporosis-related diseases), enhancing self-care awareness and active scientific intervention. In conclusion, the tertiary prevention of osteoporosis is an interrelated whole, and each group of people should focus on prevention and treatment, and the three levels of prevention should not be separated. It should be carried out under the guidance of professionals in order to achieve better results.
