The biggest misconception in the treatment of osteoporosis is that many patients believe that as long as they take enough calcium supplements, their osteoporosis should get better, or at least should not be further aggravated. However, according to the author’s experience, for many patients, calcium supplementation alone often does not satisfy the maintenance of the body’s total bone calcium, and even some patients with very comprehensive diets who should not have been taking calcium supplements have been taking them very wrongfully for many years, but the bone mass is still very low. Therefore, for the general public, it is important to know a little about osteoporosis, which after all concerns the later life of tens of millions of elderly osteoporosis patients. In the human body, bones are not static, older bones are constantly removed and new bones are produced. Osteoclasts are a type of bone cell that perform the function of bone resorption. Osteoclasts and osteoblasts are the functional counterparts. Both synergize and play an important role in the development and formation of bones. However, in patients with osteoporosis, the function of osteoclasts is dysfunctional and excessive bone mass is constantly destroyed and loss occurs, while new bone cannot be replenished in a timely manner, which is why many elderly people with calcium supplementation also have osteoporosis. For many people with osteoporosis, the amount of calcium taken is not nearly enough to cover the amount of calcium lost from the bones, so the focus of treatment should also be on reducing bone calcium loss, which means inhibiting the function of osteoclasts. In recent years, medical science has made breakthroughs in this area, and many new treatments have emerged, including injections and infusions for osteoporosis, and nasal sprays for osteoporosis, but the key is to proceed scientifically under the guidance of a specialist, rather than taking oral calcium supplements in a uniform manner.
