Infant farts may be caused by normal physiological factors, such as the mother’s diet containing more gas-producing foods, unreasonable addition of complementary foods, improper feeding, etc. It may also be caused by pathological factors, such as lactose intolerance, enteritis, etc. Parents are generally required to reasonably adjust the infant’s diet structure and use probiotics and other drugs appropriately to help adjust the infant’s gastrointestinal function. I. Physiological factors: 1. The mother’s diet: for infants who are still drinking breast milk, if the mother consumes more gas-prone foods, such as beans, sweet potatoes, etc., it will cause the infant to fart. At this time, you need to adjust the mother’s diet, so that mothers eat less gas-producing food, eat more fresh vegetables and fruits; 2, supplemental food added unreasonably: for infants who are already adding supplemental food, if the supplemental food has too much protein, fat, beans, etc., it may lead to indigestion and farting. At this time, parents should adjust the baby’s diet, eat less protein and fatty foods, eat more fresh fruits and vegetables; 3, improper feeding: usually the gastrointestinal tract function of infants are not yet well developed, so the digestive function is still weak, at this time, if the baby to eat cooler or stimulating food, or feeding posture is not correct, too many times breastfeeding, etc., are likely to lead to indigestion, so that the intestinal peristalsis abnormal, and will fart. In turn, they will release fart. At this time, you can give the baby probiotics, by improving the intestinal environment to promote the digestion and absorption of food, and secondly, the daily food to the baby should ensure that the temperature is appropriate, and at the same time to eat less and more meals, the mother should learn the correct feeding posture. Second, the disease factor: 1, enteritis: enteritis is mostly caused by bacterial or viral infection, will cause the intestinal flora imbalance, so that the infant fart, followed by the affected child often accompanied by diarrhea, abdominal pain and other symptoms. At this time, under the guidance of a doctor, infants can be given montelukast, loperamide and other medication; 2, lactose intolerance: for some lactose intolerant infants, abdominal pain, diarrhea, bloating, discharge fart and other symptoms will occur after eating milk products containing lactose. At this time, infants can take lactase to help break down lactose and improve the symptoms; secondly, infants should be given less lactose-containing dairy products in daily life. Note: In daily life, when the baby has finished eating, parents can help the baby massage the abdomen to promote intestinal peristalsis. At the same time, for infants who have added complementary foods, the complementary foods should be light and easy to digest, and less high protein, high fat or soy foods should be given to infants, so as not to increase the burden on the baby’s gastrointestinal tract.
