Bone spurs are a common need for calcium supplements. Bone spurs and osteoporosis often co-exist in degenerative bone and joint disease in the elderly. Bone spurs are actually a warning of bone loss and aging. The root cause of bone spurs is calcium deficiency, which is caused by ectopic calcium deposition during the compensatory process after osteoporosis. Calcium supplementation can correct the calcium deficiency state of the body, thus partially correcting this abnormal process, reducing the formation of bone spurs, and even making the spurs that have already formed smaller. Therefore, patients with bone spurs still need calcium supplementation. In daily life, patients can eat more calcium-rich foods, such as milk, soy products, green leafy vegetables and so on. Attention should also be paid to the supplementation of protein and various trace elements. If patients with bone spurs experience symptoms such as severe joint pain, deformity, and restricted movement, they should go to the hospital for further diagnosis and treatment in time.
