Colic is a pain caused by spasms in the large intestine, which is mainly dominated by abdominal pain and accompanied by vomiting and diarrhea. Specific as follows: 1. Abdominal pain: generally dominated by paroxysmal abdominal pain. When the intestines are stimulated after improper diet or eating unclean food, it will cause rapid contraction of intestinal smooth muscle and accelerated peristalsis, which in turn leads to abdominal pain. 2. Vomiting: It may be related to indigestion. When the peristalsis of the gastrointestinal tract is slowed down and the food is retained in the stomach, gastroesophageal reflux may occur, causing symptoms such as vomiting. 3. Diarrhea: Mostly related to colic caused by enteritis, the peristalsis of the intestinal tract is accelerated, causing intestinal spasm, and the abdominal pain will be alleviated after excretion. If the above symptoms persist and are accompanied by other uncomfortable symptoms, it is recommended to consult a doctor in a timely manner to clarify the cause of the disease and then targeted treatment.
