Osteoporosis brings great inconvenience and pain to patients’ lives, and the treatment is very slow, once the fracture can be life-threatening, therefore, special emphasis should be placed on the implementation of the three levels of prevention. Primary prevention: We should start with children and adolescents, such as paying attention to reasonable dietary nutrition and consuming foods with high Ca and P content, such as fish, shrimp, shrimp skin, kelp, milk (250ml contains Ca300mg), dairy products, bone broth, eggs, beans, refined grains, sesame seeds, melon seeds, green leafy vegetables, etc. Secondary prevention: When people reach middle age, especially women after menopause, bone loss is accelerated. Bone density check should be conducted once a year during this period, and preventive and curative measures should be taken early for people with rapid bone loss. Tertiary prevention: Patients with degenerative osteoporosis should be actively treated with drugs that inhibit bone resorption (estrogen, CT, Ca) and promote bone formation (active Vit D), and should also strengthen measures to prevent falls, bumps, trips and upsets. Summary: By strengthening the awareness of self-care, improving the level of self-care and actively carrying out scientific interventions, degenerative osteoporosis can be delayed and prevented, which will have important and realistic social and economic benefits to improve the physical and mental health and quality of life of hundreds of millions of middle-aged and elderly people in China.
