Umbilical hernias can be painful because they may become incarcerated or even rupture. An umbilical hernia occurs when the area has not completely closed, allowing abdominal organs, such as the omentum or intestines, to enter the hernia sac. If incarceration persists for an extended period, it can cause localized pain and even symptoms of nausea and vomiting. For umbilical hernias, we generally advocate conservative treatment within the first six months, as most patients can heal on their own. If the diameter of the umbilical ring is still greater than 1.5 cm after the age of two, we recommend surgical treatment. The conservative treatment for umbilical hernia involves using a coin or a flat board, larger than the umbilical ring, wrapped and pressed against the ring, and then secured with wide adhesive tape. This method can prevent the hernia from protruding and promote healing.
