Patient's question:
I didn't have constipation problems before, but recently I've been getting constipated quite often. I don't think I've been eating much, just that I've been taking calcium supplements lately. Do you think taking calcium supplements could cause constipation?Doctor's answer:
Taking calcium supplements can potentially cause constipation, because calcium carbonate has the highest absorption rate in calcium supplements and is commonly used by adults. However, the body has a process for metabolizing calcium. Under the action of stomach acid, a small portion of calcium carbonate is converted into calcium chloride, which then forms calcium phosphate in the intestines. These calcium salts are difficult to metabolize and can inhibit intestinal movement, potentially causing constipation. It is recommended to engage in appropriate exercise regularly to promote bowel movements.
