Nowadays, due to the vigorous propaganda of various media, middle-aged and elderly people are paying more and more attention to calcium supplementation and osteoporosis, but the introduction of various media on how to be calcium deficient and how to be osteoporosis is not detailed enough and not professional enough. Here is a simple introduction to all middle-aged and elderly friends. First, let’s briefly explain what osteoporosis is: osteoporosis is explained in the most easily understood way as a manifestation of aging in the bones, just as people grow wrinkles on their faces when they reach a certain age, it is a manifestation of aging in the bones. Specifically, there is a decrease in bone mass and a decrease in bone quality. The diagnostic criterion is 2.5 standard deviations lower than the average of the peak bone mass of the population. When you look at the T value in the BMD report, if it is -2.5 or less, then it is definitely osteoporosis. If it is a reduction of 1.5 standard deviations is osteopenia. These are diseases that need to be treated. Treatment of osteoporosis is not simply a matter of calcium supplementation. This is because in elderly patients, especially in postmenopausal women, there is a large amount of bone loss due to active osteoclasts and insufficient bone formation. Calcium supplementation alone can never change this situation. For treatment there are several drugs that can inhibit osteoclasts: commonly used are salmon calcitonin, sodium allantoin phosphate, and a selective estrogen receptor modulator. Adding these drugs to calcium supplementation, or adding herbs to improve bone quality, is the only way to achieve therapeutic results. Another thing is how much calcium you need per day. A normal adult needs 1500mg of calcium per day, but the Chinese diet provides about 600-800mg of calcium per day, which means that there is a shortage of about 750mg of calcium. From these two figures, we can see that according to the Chinese diet, most Chinese people are deficient in calcium in their diet. Therefore, a little calcium should be supplemented appropriately. That means 750mg of calcium can be supplemented daily. But for patients with osteoporosis, more supplementation is needed, which should be 1500~2100mg per day. according to the classical literature, calcium carbonate is more easily absorbed. The above is a little bit of my own learning and treatment of osteoporosis experience to share with you. I have not been on the Internet for a long time because of my busy work schedule, and I am very happy to see that many people have viewed this article that I published before. So I will update the above content again, and hope it will be helpful to all middle-aged and elderly people. The Committee of Bone Mineral Salt of the Orthopaedic Branch of the Chinese Medical Association has integrated the opinions of all osteoporosis experts and reformulated the guidelines for the treatment of osteoporosis. First, regarding the standard of bone mass reduction, it was changed from the previous reduction of 1.5 standard deviations to a reduction of 1.0 standard deviations. First, if a patient is found to have reduced bone mass on examination and also has risk factors for osteoporosis (low weight, history of osteoporotic fracture in the immediate family, smoking, diabetes), anti-osteoporosis treatment should be started. Third, the new anti-osteoporosis drugs: 1, diphosphonates The new drugs in this category is MIGUDA, intravenous drip, once a year, easy to use, anti-bone resorption effect is significant. 2.Drugs that promote the formation of new bone: strontium ranelate The drug is not yet covered by the reimbursement. 3, new drugs to promote new bone formation: Foteo (teriparatide injection), which is suitable for patients with osteoporosis combined with fractures.
