钙以离子形式通过肠壁细胞吸收。食物或钙补充剂中的大部分钙以溶解度较低的盐的形式存在,而这些盐的溶解度取决于环境pH值,故胃酸分泌对于正常的钙吸收是必需的。然而,有关胃酸缺乏患者从不溶性钙盐中吸收钙的效率的资料很少,故很有必要对此问题进行探究。治疗钙缺乏的最常见? Calcium is absorbed ionically by the intestinal cells. Most of the calcium in food or calcium supplements is in the form of less soluble salts, and the solubility of these salts depends on the pH of the environment so that gastric acid secretion is essential for normal calcium absorption. However, there is very little information on the efficiency of calcium absorption from insoluble calcium salts in patients with achlorhydria, so it is necessary to explore this issue. The most common treatment of calcium deficiency?
