Patients with osteoporosis will be greatly relieved or regain their physical ability if they can adhere to the following points. First, adequate physical activity should be maintained. Stick to physical exercise at least 30 minutes a day, 3-5 times a week. You should also try to supplement calcium from food, expand the variety of food, and eat more calcium-containing food, such as spinach, leek, mushrooms, fish, bone broth, milk, etc. The next step is to supplement vitamin D, more sunshine to promote calcium absorption; use the drug calcitonin or bisphosphonates to inhibit osteoclast activity and inhibit bone resorption, and for postmenopausal women, hormone replacement therapy can also be used to supplement estrogen to prevent bone loss. Osteoporosis emphasizes the implementation of the three levels of prevention: 1, primary prevention: should start with children and adolescents, such as attention to reasonable dietary nutrition, more food containing high Ca, P, such as fish, shrimp, shrimp, kelp, milk (250ml contains Ca300mg), dairy products, bone broth, eggs, beans, refined grains, sesame, melon seeds, green leafy vegetables, etc.. Try to get rid of “risk factors”. Adhere to a scientific lifestyle, such as adhere to physical exercise, more sunbathing, do not smoke, do not drink alcohol, less coffee, strong tea and carbonated beverages, less sugar and salt, animal protein should not be too much, late marriage, less childbirth, breastfeeding period should not be too long, as much as possible to preserve calcium in the body, enrich the calcium pool, increase the peak bone to the maximum is the best measure to prevent osteoporosis later in life. Strengthen the basic research of osteoporosis, focus on follow-up and early prevention for the high-risk group with genetic genes. 2.Secondary prevention: bone loss accelerates in middle age, especially after menopause in women. Bone density check should be conducted once a year during this period, and prevention and control measures should be taken early for people with rapid bone loss. In recent years, most scholars in Europe and the United States advocate starting long-term estrogen replacement therapy within 3 years after menopause, and at the same time insisting on long-term preventive calcium supplementation or using bone peptide oral preparation bone peptide tablets for preventive treatment, in order to safely and effectively prevent osteoporosis. In Japan, it is mostly advocated to prevent osteoporosis with active VitD (rocalciferol) and calcium, and to pay attention to the active treatment of diseases related to osteoporosis, such as diabetes, rheumatoid arthritis, steatorrhea, chronic nephritis, hyperparathyroidism/hyperthyroidism, bone metastasis cancer, chronic hepatitis, liver cirrhosis, etc. 3.Tertiary prevention: Patients with degenerative osteoporosis should be actively treated with medication to inhibit bone resorption (estrogen, CT, Ca), promote bone formation (active Vit D), oral preparation of bone peptide (bone peptide tablets), and should also strengthen measures to prevent falls, bumps, trips and upsets. For middle-aged and elderly patients with fractures should be actively operated, implement strong internal fixation, early activity, physical therapy, physiotherapy psychological, nutrition, calcium supplementation, pain relief, promote bone growth, curb bone loss, improve immune function and overall quality and other comprehensive treatment. Degenerative osteoporosis is the basic law of bone development, growth and aging, but is subject to hormonal regulation (mainly PTH bone breaking: estrogen, CT osteogenesis; VitD3 two-way regulation), nutritional status, physical factors (sunlight, weight), immune status (systemic physique, disease), genetics, lifestyle (smoking, alcohol, coffee, eating habits, exercise, mental and emotional), economic and cultural If we can strengthen the awareness of self-care, improve the level of self-care and actively intervene scientifically, it is possible to delay and prevent degenerative osteoporosis, which will be of great significance to improve the physical and mental health and quality of life of hundreds of millions of middle-aged and elderly people in China.
