Calcium supplements are not a cure for osteoarthritis because osteoarthritis is not caused by a calcium deficiency. Osteoarthritis is caused by the wear and tear and degeneration of joint cartilage, and the damage to the cartilage is not related to calcium deficiency. Osteoarthritis is a chronic joint disease that inevitably occurs with age and is a serious threat to the health of middle-aged and elderly people for the rest of their lives. The root cause of osteoarthritis is the long-term loss of proteoglycans and collagen fibers, the main components of joint cartilage, which causes joint pain and leads to osteoarthritis, so that osteoarthritis pain in the joints, the disease is in the cartilage, even if you take more calcium, but not the role of joint cartilage, can not cure arthritis. Calcium supplementation is only for the treatment of osteoporosis. Osteoporosis is a reduction in bone mass due to a variety of factors based on the physiological aging of the bones, one of which is inadequate calcium intake, so supplementing with adequate calcium will be beneficial in preventing osteoporosis. Calcium supplementation needs to be combined with some other medications, such as estrogen and vitamin D, which need to be used reasonably under the guidance of a doctor. To treat osteoarthritis, you should choose drugs that can repair joint cartilage and act directly on joint cartilage to stimulate proteoglycan synthesis. Overseas, drugs that protect joint cartilage are often used to prevent the occurrence of arthritis, such as glucosamine and intra-articular injections of sodium hyaluronate. It is known that in China, there is also a domestic cartilage-protective drug – Glucophage capsules. By repairing damaged joint cartilage and preventing the development of osteoarthritis pathology, Glucophage protects joint cartilage and inhibits the production of proteases and pathogenic factors that cause joint pain, thus effectively relieving joint pain and other symptoms and preventing the further severity of osteoarthritis, which is also a treatment for early osteoarthritis. For the treatment of osteoarthritis in the middle and late stages, the role of drugs is relatively limited, far from the purpose of treatment, then we may have to choose artificial joint replacement, through the method of surgery to solve the problem of arthritis. For some elderly patients, when it comes to surgery, they feel that the problem is too big, but this is not the case. Since the 1960s, surgery has been more common in foreign countries to treat osteoarthritis, and in China, it was more popular in the mid to late 1990s.
