In cases of umbilical hernia, applying heat generally has no effect. For infants, it is often acceptable to observe conservatively until the child is about two years old. Adhesive tape therapy can be used in this period. By the age of two, the umbilical ring in most children will close on its own. For those over two years old with an umbilical ring diameter still greater than 1.5 cm, surgery should be considered. For patients over five years old, it is generally recommended to undergo surgery sooner rather than later. In adults, the causes of umbilical hernias are mainly due to factors such as pregnancy, excessive fat in the greater omentum, chronic coughing, cirrhosis with ascites, etc., which increase abdominal pressure. Incarceration can occur, involving either the greater omentum or the small intestine, and surgery is usually the chosen treatment method, either through traditional tissue repair techniques or open tension-free hernia repair. In some cases, laparoscopic umbilical hernia repair may be chosen when necessary.
