Many people will find that they are getting shorter when they get older, and sometimes they will have back pain and limb weakness. These seemingly normal aging phenomena are actually caused by a disease – osteoporosis. < / P > < p > osteoporosis is known as the “invisible killer”, mainly because suffering from osteoporosis early without obvious symptoms, with the growth of age, bone calcium gradually loss, once there are obvious symptoms, such as pain, bone deformation, fracture, bone calcium loss is often more than 50%, short-term treatment is difficult to work. < / P > < p > patients will have systemic pain. The most common parts of bone pain are the waist, back, hip and limbs. The most common part is low back pain, which spreads to both sides along the spine. The pain of sedentary and standing is aggravated. The pain of osteoporosis was alleviated in the day, and severe in the night. < / P > < p > patients will have the symptoms of bone deformation. The vertebral body is mostly composed of cancellous bone, which is the pillar of the body. It is easy to compress and deform with the largest load, making the spine forward, aggravating the curvature of the back, forming a hunchback. With the growth of age, osteoporosis worsens, and the curvature of the hunchback increases, making the knee joint contracture significant and walking lame. < / P > < p > patients will have brittle fracture. According to the reports, the most serious complications of the patients were in the thoracic, femoral and heart fracture. The most serious complications were in the thoracic, femoral and heart fracture. < p > > in postmenopausal women, the synthesis of estrogen and the secretion of estrogen were significantly decreased. The decline of estrogen level will lead to the content of bone salt, and eventually develop into postmenopausal osteoporosis. < / P > < p > there is a steady state of calcium and phosphorus balance in normal human body. They interact with each other and are regulated by a variety of hormones. The factors controlling the stability of calcium and phosphorus include parathyroid hormone, vitamin D, growth hormone and the utilization of phosphorus in diet. The abnormal function of the above factors can cause secondary phosphorus metabolism disorder, and also lead to bone matrix synthesis and mineralization disorders, and eventually lead to osteoporosis. < / P > < p > with the growth of age, the exercise of the elderly decreases, the muscle strength gradually weakens, the stimulation of bone mechanical stress weakens, and the ability of bone reconstruction weakens. With different degrees of muscle atrophy, the speed of bone formation decreases, which will cause the imbalance of calcium and phosphorus metabolism in the body, leading to the decrease of bone mass and osteoporosis. < / P > < p > this kind of food refers to osteolipoprotein, which is called the nutritional supplement of articular cartilage. It can be used as a pipeline to transport important oxygen supply and nutrients for cartilage, and eliminate carbon dioxide and wastes at the same time. Since articular cartilage has no blood supply, all the oxygenation, nourishment and lubrication come from synovial fluid; at the same time, it can also reduce bone loss So as to strengthen bone, improve bone mineral density and prevent osteoporosis. < p > < p > secondly, osteolipoproteins have a certain regulatory function on liver and kidney function, which can promote intestinal calcium absorption faster than taking calcium tablets directly. It is easier for the body to absorb and improve bone metabolism. Compared with calcitonin and estrogen replacement therapy, osteolipoproteins have more extensive effects. < / P > < p > orthopedic director: 1 kind of food, insist on eating, enhance bone density, bone will thank you. If you want to keep your bones healthy, you should develop a good lifestyle and eating habits, exercise more and stay up late less. After pregnancy, do not let the wife do these five kinds of housework, the husband should be responsible for it, otherwise it is easy to hurt the fetus!
