Generally, the causes of newborn babies’ poop when hiccuping mainly include the following situations, first of all, it is due to the symptoms caused by gastrointestinal dysfunction. If the gastrointestinal dysfunction will often lead to loose stools, after hiccups will lead to increased abdominal pressure, abdominal pressure increases after the stool will be easy to come out, which leads to hiccups on the stool, to apply probiotics to regulate, such as the application of mamma love. Secondly, it is caused by immature development of anal sphincter, some newborns’ anal sphincter is not mature congenitally, and the tension of anal sphincter is relatively low, which will cause pooping when the abdominal pressure increases after hiccups, and most of them will get better with the increase of age.
