Infant umbilical hernia occurs due to a weak abdominal wall in the navel area and incomplete prenatal development. It generally poses no significant harm, but measures should be taken to prevent frequent protrusion of the hernia. It is usually advisable to avoid excessive crying and prolonged episodes of crying in children, and to actively prevent and treat digestive system diseases in children to reduce the chance of increased gas in the gastrointestinal tract and increased abdominal pressure, which can lead to protrusion of the navel and discomfort for the child. Therefore, in over 80% of children with umbilical hernias, the hernia ring will gradually narrow and shrink as the child grows and develops physically, achieving healing by the age of two. Only less than 20% of children, particularly those with a hernia ring diameter greater than 2cm, or who clearly have an umbilical hernia at the age of two, will require surgical treatment.
