With the rapid improvement of living standards, having a healthy body and good disease prevention are becoming more and more important in people’s lives. Many middle-aged and elderly people also take calcium tablets and other nutritional products all year round in order to prevent osteoporosis, which shows that the public attaches great importance to bone health. The onset of osteoporosis is related to the primary osteoporosis associated with menopause and old age, in addition to a variety of diseases such as endocrine diseases, gastrointestinal and nutritional diseases, blood system diseases or long-term drug use, known as secondary osteoporosis. So what kind of people are at high risk of osteoporosis? 1.Inherent factors: old age, female menopause, maternal family history. 2, non-inherent factors: low weight, hypogonadism, smoking, excessive alcohol consumption, coffee and carbonated beverages, lack of physical activity, long-term bed rest, imbalanced diet, high sodium diet, lack of outdoor exercise, diseases affecting bone metabolism or application of drugs affecting bone metabolism (glucocorticoids, immunosuppressants, heparin, anticonvulsants, anticancer drugs, aluminum-containing antacids, thyroid hormones, GnRH-a or dialysis solution, etc.). We are familiar with the dangers of osteoporosis, because the symptoms of bone deformation and pain caused by osteoporosis can greatly reduce the quality of life of patients and bring burden to families, so when we enter middle age, we should pay more attention to bone health, and it is very important to do a good job of prevention: 1. People in middle age, career and family may make people overwhelmed, but then busy to find time for physical exercise. Because exercise can promote the body’s metabolism, and exercise in the muscle contraction, the direct action on the bone pull can also enhance the strength of the bone and bone mass. Especially outdoor sports can receive the right amount of sunlight, which is conducive to the absorption of calcium. 2, eat the right calcium can be supplemented. Eggs, fish and shrimp, beans, milk, seafood and vegetables are rich in calcium ions that can be absorbed by the human body, in the daily diet is not picky, reasonable mix is conducive to increasing calcium intake. In addition, you can also properly supplement calcium and vitamin D. Vitamin D is the carrier of calcium ions absorbed by the bone marrow, so that the body’s ability to absorb calcium ions increased exponentially. 3, change the bad habits of life. Do not smoke, less alcohol, less stimulating drinks can reduce the body’s calcium loss. Alcohol and tobacco in harmful substances can make the bone lower, and strong coffee will increase urinary calcium excretion, affecting the body’s absorption of calcium. 4, maintain a good mood. Excessive stress on the human immune and metabolic system will have an impact, but also many disease factors, so we should learn to regulate stress in life and work, to maintain a good state of mind and mood and physical state. 5, regular medical checkups to seek professional help. Since osteoporosis occurs for a wide variety of reasons and secondary causes, we should make it a habit to have regular medical checkups every year and seek help from doctors as early as possible when problems are found.
