Infant umbilical hernia is caused by poor congenital development of the navel, resulting in protrusion of the umbilicus. Usually, as the child ages, the hernial ring gradually narrows and closes, and 80% of such cases can close on their own. However, there are a few cases, such as those where the hernial ring diameter is too large, especially more than 2cm, or those that do not close by the age of two, which require surgical treatment. During this period, it is usually necessary to avoid situations that may cause increased abdominal pressure in the child, leading to protrusion of the navel, such as preventing the child from crying intensely. For instance, if the child exhibits gastrointestinal symptoms, they should be taken to the doctor for timely examination and treatment.
