Infantile colic can cause constipation. It is first important to understand that colic is caused by abnormal intestinal movements and stimulation of the intestinal mucosa, leading to pain symptoms. This is often due to increased intestinal gas or constipation, which disrupt normal intestinal movements and thus also cause symptoms of constipation. In such cases, one can first try abdominal massage to promote intestinal movements and help the expulsion of gas and stool, thereby alleviating symptoms. Additionally, taking probiotics orally can regulate gastrointestinal function and aid in digestion and absorption. Attention should also be paid to dietary adjustments, preferably eating light and easily digestible food to reduce the production of intestinal gas and alleviate its symptoms. If symptoms persist for a long time without significant relief, it is still necessary to have a specialist doctor examine and prescribe medication accordingly.
