htmlOctober 20 is World Osteoporosis Day . This year's promotional theme is "Consolidate your life, 'win' to fight fractures." osteoporosis is a systemic bone disease that increases bone fragility and is prone to fracture due to low bone mass and damage to bone tissue microstructure. According to statistics, about half of the people over 50 years old in my country have bone mass reduction, and nearly 20% of people suffer from osteoporosis . It is generally believed that osteoporosis is calcium deficiency. In this regard, , deputy chief physician of orthopedics at the First Hospital of Peking University, , Yu Zhengrong, said that calcium supplementation alone cannot treat and prevent osteoporosis: "Calcium supplementation can prevent osteoporosis, which is false. The bones of our human body are usually in a dynamic balance state, that is, the formation and absorption of bones are balanced and stable. When we are old or , the dynamic balance is broken, and bone absorption is significantly greater than the formation of bones. The bone mass of will gradually decrease, and even osteoporosis occurs, so calcium supplementation alone is not enough."
Despite this, it is still necessary for the elderly to appropriately increase calcium intake. Yu Zhengrong said: "The daily calcium intake of Chinese people is only 400 mg, while the daily calcium demand for adults is 800 mg. For middle-aged and elderly people over 50 years old, we recommend that calcium intake be increased to 1,000 to 1,200 mg per day. Therefore, in addition to our original dietary intake, it is necessary to supplement calcium appropriately."
So, what role can exercise play in preventing osteoporosis? Wu Xiaoliang, deputy chief physician of the Department of Spinal Orthopedics at Southern Hospital of Southern Medical University, introduced: "Exercise can promote bone growth and increase bone mass, improve muscle coordination and avoid the occurrence of fractures. In addition, attention should be paid to avoid bad living habits, including sitting for a long time, not exercising, smoking and drinking, etc. There are also studies that drinking a lot of carbonated beverages and coffee can also lead to osteoporosis."
Deputy Chief Physician of Orthopedics at Dongzhimen Hospital of Beijing University of Traditional Chinese Medicine Liu Xiangchun said: "There is a simple and practical law in orthopedics-Wolf's law, that is, bones grow in the direction of stress. If people exercise more and bear more weights, the hardness of the human bones will be higher; if they always lie down or sit still, the bones will not bear weights, and under the self-induced human body, the calcium deposited in the bones will become less."
