Umbilical hernia

  • Symptoms

    A hernia can vary in width from less than 1 centimeter to more than 5 centimeters.

    There is a soft swelling over the belly button that often bulges when the baby sits up, cries, or strains. The bulge may be flat when the infant lies on the back and is quiet.

    Signs and tests

    The doctor can find the hernia during a physical exam.
