Can taking calcium supplements cause constipation?

Taking calcium supplements may cause constipation.
Calcium supplements are mainly used to supplement the calcium needed by the human body. The calcium content in calcium supplements is not easy to be absorbed in the intestines, only a small portion of the calcium content can be absorbed into the blood, and most of the calcium content will be combined with phosphoric acid and oxalic acid in the intestines to form calcium phosphate and oxalic acid, which will affect the peristalsis of the intestinal tract, causing the accumulation of feces in the intestinal tract and inducing constipation.
If the constipation is mild, patients can adjust their lifestyle by eating more dragon fruit, banana, sweet potato, celery, etc., and at the same time, more physical exercise, which can usually improve the symptoms of constipation.
If the constipation is more serious, or the above methods are not satisfactory, should be timely to the regular hospital, under the guidance of the doctor for targeted treatment, in order to reduce the adverse effects of the disease.
