Why is the navel swollen after a newborn's umbilical cord falls off?

Patient's question:

No

Doctor's answer:

A hernia is a weak spot or tear in the abdominal muscles, causing fat tissue or other organs like intestines to push through this area and form a noticeable bulge under the skin, accompanied by discomfort and pain. Symptoms are often more pronounced during prolonged standing, urination, defecation, or lifting heavy objects. There is no medication to treat a hernia; the only option is surgical repair to fix the defect.
