Skeleton is one of the important parts of human body. There are 206 bones in our body, accounting for about one fifth of our weight. They are connected by joints to form a scaffold of the body, protect internal organs, provide attachment points for muscles to facilitate physical activities, participate in blood production, and store calcium and phosphorus. Osteoporosis is also called "silent disease". Changes in bone strength often occur when we cannot perceive them! In the early stage of osteoporosis, there is often no obvious external performance, which is easy to be ignored. Many people realize that they have osteoporosis after fracture. Experts from the Beijing Center for Disease Control and Prevention said that in life, our six bad habits will increase the risk of osteoporosis. Come and check yourself! Smoking, excessive drinking and smoking will double the risk of hip fracture. Excessive alcohol consumption also increases the risk of fractures. Body mass index is too low due to excessive weight loss Body mass index (kg/m2)=body weight (kg)/height 2 (m2). If it is less than 18.5, it belongs to underweight, which is also an important risk factor. Partial diet causes malnutrition. Daily diet, such as lack of calcium, protein, fresh vegetables and fruits, is not conducive to bone health. "Malnutrition" is the main problem faced by the elderly, who are at higher risk of falls and fractures. Therefore, adequate calcium and protein intake should be ensured in the diet. Low levels of vitamin D are common among people with osteoporosis, especially among the elderly who do not often go outdoors. Therefore, we should try to ensure that there is sufficient sunlight every day. Lack of physical activity can lead to bone and muscle loss. People who are inactive are more likely to have hip fractures. Strengthening physical exercise, focusing on resistance resistance and aerobic exercise and persisting in it for a long time, will be beneficial to bones. People who often fall and tend to fall have a higher risk of fracture. The elderly have the highest risk of osteoporosis. In addition to adhering to a healthy lifestyle, the elderly also need to pay attention to preventing falls. The elderly can participate in some sports to improve their balance, coordination and muscle strength, such as the towel exercise, which has been promoted by the disease control system for many years. In addition, bone health assessment should be carried out in professional institutions to ensure early detection, early diagnosis and early treatment, so as to obtain better health benefits.
