Infantile flatulence and crying may be due to physiological reasons, such as incorrect breastfeeding posture, adjusting the breastfeeding posture can be relieved. It may also be due to pathological reasons, such as congenital megacolon, anal atresia and other diseases, the treatment includes surgical treatment. 1. Physiological causes: Incorrect breastfeeding posture can cause air to be mixed in with the milk when the baby is eating, which in turn leads to flatulence in the newborn. The symptoms can be relieved by adjusting the breastfeeding position, avoiding feeding when the baby is crying, and holding the baby upright to burp after feeding. 2. Pathologic causes: Congenital megacolon: Congenital megacolon is a common disease with abnormal development of enteric neurons. The disease is actually caused by the absence of ganglion cells in the distal colon due to polygenic inheritance and environmental factors. Once the disease is diagnosed, radical surgery should be performed to remove the ganglion cell-free intestinal segment and part of the dilated colon. Anal atresia: Anal atresia is the most common type of congenital rectoanal malformation. Anal atresia may be associated with genetic factors, among others, and is an anomaly of early embryonic development. Anal atresia needs to be treated with surgery. If an infant or young child has a bloated stomach and cries, he or she should go to the hospital in time to avoid delaying the condition or triggering adverse reactions.
