In children with umbilical hernia, crying can easily lead to an increase in intra-abdominal pressure. As the intra-abdominal pressure increases, gas in the intestines and mesentery can easily protrude through the unclosed umbilical ring, thereby exacerbating the symptoms of the umbilical hernia. In severe cases, this could lead to serious complications such as incarceration of the hernia. Therefore, in addition to not crying, children with an umbilical hernia should also avoid constipation, coughing, and vigorous activities that could increase intra-abdominal pressure, in order to prevent worsening of the hernia symptoms. In daily life, their diet should be light and easy to digest.
