Colic mostly occurs in infants under 3 months of age.
The main symptoms of colic are loud bouts of crying, redness of the baby’s face, pallor around the mouth, distended and tense abdomen, legs curled upward, cold feet, and clenched hands, which cannot be relieved by picking up or feeding, and eventually stopping with exhaustion, exhaustion or defecation. It is usually caused by the incomplete development of the digestive tract and the weak immune system of infants under 3 months of age. When infants are fed milk, the air enters the gastrointestinal tract with sucking and stimulates the intestinal tract and causes colic; or overfeeding causes colic due to excessive expansion of the gastrointestinal tract; infants with milk allergy also have colic; in addition, some infants with congenital heart disease and premature babies are prone to irritation, which can also cause colic. When the infant’s age gradually increases, the development of the gastrointestinal tract gradually improves, the immunity gradually strengthens or some organic lesions are cured, the colic will slowly disappear.
Therefore, if an infant has colic, he or she should go to the hospital immediately if there is fever, vomiting and blood in the stool.
