Patients often ask in the clinic, “Are the bone spurs due to excessive calcium supplementation? This is a misconception. Bone spurs, medically called osteophytes, do not occur after calcium supplementation, but are symbiotic with osteoporosis, both caused by calcium deficiency, and are two bitter melons on one vine. Osteoporosis is a systemic bone disease that manifests itself as a qualitative and quantitative lesion within the bones because of the abnormal endocrine metabolism of the human body, the reduction of bone mass and the destruction of the microstructure of the bones. Osteoporosis is a comprehensive syndrome that is closely related to changes in hormonal regulation, nutritional status, exercise, sunlight, immune function and genetics. Osteoporosis is caused by the degeneration and degeneration of soft tissues such as cartilage, intervertebral discs and ligaments that make up the joints, and the formation of bone spurs at the edges of the joints, resulting in joint deformation and causing symptoms such as joint pain and restricted movement when subjected to abnormal loads. ”In clinical practice, osteophytes and osteoporosis often coexist, and osteoporosis can exacerbate the formation of osteophytes”, the bone in the body is a living tissue that is constantly carrying out metabolic activities. bone volume enters its peak around the age of 28, and later bone volume is gradually declining. After middle and old age, the degeneration of human organs occurs, especially the reduction of gastric acid, pepsin and salivary gland secretion and the activity of digestive enzymes, which makes its calcium intake, digestion and absorption seriously affected, and the human body is in a negative calcium balance. The direct consequence of insufficient calcium intake is low blood calcium, which can trigger a series of serious pathological reactions, when the body’s blood calcium self-stabilization system, that is, increased secretion of parathyroid hormone, dissolve bone calcium, so that the calcium in the bone into the blood to replenish the blood calcium and maintain the original level of blood calcium. In a person with normal calcium metabolism, a short term calcium deficiency will not normally lower blood calcium. However, if the body is chronically deficient in calcium and it is not corrected, the parathyroid glands will continue to be stimulated by calcium deficiency, over-secreting parathyroid hormone and dissolving too much bone calcium. This results in the paradoxical phenomenon of decreased bone calcium and increased blood calcium levels, known medically as hypercalcemia. High blood calcium stimulates increased calcitonin secretion and promotes osteogenesis, which is the hormonal basis for the coexistence of osteoporosis and osteomalacia. Osteomalacia is just a compensation of the body for osteoporosis, and the calcium deposits that should enter the inside of the bones are repaired on some of the most stressed bone surfaces, such as the cervical vertebrae, lumbar vertebrae heel bones, etc., thus forming bone spurs. Therefore, osteoporosis and osteomalacia, which often afflict middle-aged and elderly people at the same time, are twin bone diseases caused by the lack of calcium in the body. Prevention of osteoporosis and osteomalacia should start with the prevention of calcium deficiency, pay attention to a balanced diet from a young age, strengthen sports and exercise, pay special attention to outdoor activities, more sunshine, enhance bone strength and toughness, prevent or delay the occurrence of osteoporosis and osteomalacia.
