What is the reason for the sunken navel of an infant?

Patient's question:

A full-term infant with a sunken navel below the umbilicus and bulging on both sides

Doctor's answer:

Based on the baby's condition, consider the possibility of an umbilical hernia. It is recommended that you take your child to the pediatric department of the hospital for a consultation, so that the doctor can personally examine them to confirm the diagnosis. The majority can heal on their own within one year through the gradual contraction of the umbilical fascial ring. Before the age of two, unless there is strangulation, it is acceptable to wait and use non-surgical methods to promote self-healing. After the child turns two, surgical treatment is recommended.
The child is troubled by neonatal diseases, so the mother must take the child to the hospital for immediate medical treatment to avoid blindly using advertisements for drugs. It is necessary to use medication rationally. For parents, it is important to pay timely attention to the child's condition and do their best to help the child receive timely treatment for the disease.
