It is not necessary to take excessive calcium supplements after a fracture, because in the case of excessive calcium supplements, not only is it detrimental to absorption, but it tends to increase the harmful effects on the body, such as the occurrence of cholelithiasis and urolithiasis. After a fracture, the human body is less active and lack of exercise. In the absence of exercise, the bone will undergo disuse decalcification, which will cause an increase in calcium levels in the human body. After a fracture, the activity of osteoclasts is increased, and the increased activity of osteoclasts will break down the broken bone fragments at the fracture end into calcium ions to promote the absorption of calcium, providing a large amount of raw material for the fracture end and increasing the level of calcium in the blood. If in the case of calcium supplementation can lead to an excess of calcium, the excess of calcium through the process of excretion can lead to the occurrence of cholelithiasis or urolithiasis in the human body.
