Babies with protruding navels may be because the umbilical cord is cut relatively long, or it may be an umbilical hernia. Parents should take their babies to the doctor as soon as possible to avoid delay in diagnosis and treatment. Most babies have more or less protruding navels, which is a normal phenomenon, and if there is no other discomfort, there is no need to worry. Umbilical hernia is a congenital developmental defect disease, the navel protrudes in the child crying, constipation, coughing and other intra-abdominal pressure increases in the situation more obvious. If an incarceration occurs, urgent medical attention is needed. Umbilical hernias have the potential to heal on their own within two years of age and can be observed for a period of time. After two years of age, they are very unlikely to heal on their own, so if the umbilical hernia is still present and noticeable after two years of age, surgery may need to be considered.
