Calcium tablets can cause constipation symptoms because the main component of calcium tablets is calcium carbonate, and calcium carbonate will enter the digestive tract tissue and neutralize with gastric acid to produce calcium chloride. When calcium chloride enters the intestinal tract, it will react with bile salts in bile to form calcium phosphate, and some of the calcium phosphate will adhere to the surface of the intestinal mucosa, which will inhibit its normal peristaltic function. Excessive daily intake of calcium tablets can cause constipation symptoms, the daily diet process, some types of food can play a role in relieving constipation symptoms, such as yogurt, bamboo shoots, apples, etc.. Because the above types of food are rich in crude fiber, beneficial bacteria, minerals and other components, not only can promote the blood circulation and metabolism of the gastrointestinal tract to enhance the function of the digestive tract tissues, for the promotion of intestinal peristalsis, prevention of constipation has a therapeutic effect.
