Decreased bone mineral density, also known as osteoporosis, is a phenomenon caused by the synergy between osteoblasts and osteoclasts, which can be alleviated and improved through medication and other means. Osteoblasts and osteoclasts exist in human bones. During the metabolic process of bones, osteoclasts are responsible for dissolving and absorbing bones, while osteoblasts are responsible for regenerating and restoring bones, and osteoclasts form bone sockets in bones, which is a normal process of bone metabolism and is not a pathological reaction. Osteoblasts will move to the bone sockets and form osteoblasts. Osteoblasts will secrete collagen fibers and absorb the calcium and phosphorus components in the blood and then discharge them to attach to the collagen fibers. After a period of time, the osteoblasts will be completely wrapped with minerals, which is the process of bone mineralization and why osteoporosis patients need to take calcium supplements. Patients can treat the phenomenon of osteoporosis by supplementing calcium medication. However, with age, the human body will experience different degrees of osteoporosis, which is not a pathological phenomenon during this period, and the progress of osteoporosis can be alleviated by means of calcium supplementation, etc., but it is not possible to reverse the process.
