The essence of osteoporosis is the degeneration of bone tissue, a systemic skeletal disease characterized by reduced bone mass, degeneration of microstructure, reduced bone strength, increased brittleness and susceptibility to fracture. Osteoporosis can be silent before a fracture occurs, and once a fracture occurs, it often indicates that the osteoporosis has become very serious, and the parts prone to fracture are: thoracic and lumbar spine, wrist, hip, shoulder, etc. Osteoporosis is not the patent of the elderly, but can also occur in young people, especially young women, who prefer to eat vegetarian food and fruits in order to lose weight and shape up, prefer to drink carbonated beverages such as coffee and cola because of work tension, and avoid the sunlight for skin care so that the synthesis of vitamin D in the body is insufficient, resulting in insufficient calcium intake and absorption in the body; just when they are complacent in the “bone When they are complacent about their “bone-like” beauty, they are unaware that due to calcium deficiency and a prolonged decline in estrogen levels, the loss of calcium and strength of the bones are accelerated, and if they have bad habits such as smoking and drinking, it is easy to develop “osteoporosis” at a young age. Once osteoporosis occurs, it is very difficult to reverse, and all current treatments (diet, exercise, drugs) are not yet able to reverse the process. Therefore, the prevention of osteoporosis should be emphasized, and the measures include: ① During the period of rising and reserve bone mass (from birth to 30~35 years old), regular physical exercise and adequate nutrition should be taken to make the peak of bone mass reserve reach a high level, so that even if the slow loss of bone mass and several rapid losses occur after the age of 35, a certain amount of bone mass can be maintained and osteoporosis can be avoided. ②Exercise: High-intensity exercise is beneficial to increase bone mass, and medium-intensity exercise can increase muscle strength and body flexibility and reduce the chance of falling and the degree of injury when falling; therefore, you can choose exercises of different intensities according to your respective physical condition and exercise habits, and match them to exercise your body. ③ Healthy habits: such as regular life, quit smoking and drinking, pay attention to calcium supplement in diet, drink less coffee and carbonated beverages, and appropriately choose Chinese herbal tonic for kidney and bone strengthening. In addition, the favorable side for us is: the risk of bone loss and serious osteoporosis is lower for yellow people than for Caucasians. So if we pay attention to it from the young age and pay attention to it in our daily life, osteoporosis can be effectively prevented.
