In recent consultations, many parents have asked what to do about their children’s bloating. Abdominal distension is a very common symptom in children, and the cause varies in different age groups. 1. In younger infants and toddlers, and even in newborns, most abdominal distension is related to the fact that the child’s digestive function is not yet perfect, the intestinal peristalsis is slow, and the gas in the intestine is not easily expelled by itself. In addition, if a child is in a hurry to eat milk, he or she will swallow a lot of gas while eating milk, which also aggravates the child’s abdominal distension, and some children even have frequent symptoms of milk rippling and vomiting. In this case, just pat your back after each feeding until your child burps, or rub your belly, usually clockwise around your belly button, with a little force, until you release a few farts. This way most of the bloating can be effectively relieved. 2, some children with bloating at the same time, there will be a large amount of foam in the stool, and the stool has an obvious sour smell, which generally indicates the possibility of lactose intolerance is relatively large. Parents can make a preliminary judgment based on these typical manifestations, and if the stool galactose measurement is 3+ or more, it is basically certain that the child is lactose intolerant. This requires giving the child lactose-free formula or taking lactase. Personally, I think it is better to take lactase, because some breast-fed children, try not to change formula, adhere to breast-feeding, just take lactase orally before each feeding. 3, there are some children abdominal distension, at the same time dry stool, a few days to solve a stool, defecation when the effort, at the same time have a bad taste in the mouth, abdominal pain, poor appetite symptoms. This generally suggests that the child is accumulating food, which is also a very common situation. This situation requires parents to pay extra attention to the diet, do not let the child eat too much at a time, but to feed a small amount of times, in addition to vegetables and fruits and other coarse fiber food to eat more. This will help relieve dry stools and speed up the discharge of stools. If your child’s stool is already very dry, you can help laxative with appropriate open cork, while oral lactulose plays a role in softening the stool. In this case can also be carried out abdominal massage, will also play a very good effect. 4, older children, bloating, often related to diet, some children have overeating, or eat food too greasy, not easy to digest, the child will appear bloated, most will report abdominal pain, parents in this case to control the diet a little, avoid too greasy food. If necessary, you can take oral stomach and appetite tablets. 5, H. pylori infection: some children often bloating, and there is a bad taste in the mouth, long-term epigastric pain, especially if others in the family have H. pylori infection, pay attention to whether the child is also infected with H. pylori, which can be confirmed by carbon 13 breath test, treatment is mainly through oral medication eradication. To sum up: abdominal distension in children is a very common symptom, most of which is not too serious and is generally related to dietary structure and eating habits. Once a child’s abdominal distension is detected, it can be significantly relieved by taking appropriate measures according to the common causes in different age groups. But if the child is bloated at the same time, there is intense vomiting, abdominal pain, and even poor mental and drowsy symptoms, we must promptly seek medical attention to find the cause.
