Why does the stump protrude after umbilical cord falls off?

After the umbilical cord falls off, the remaining piece of tissue is called the umbilical stump. Initially, it protrudes from the baby's abdomen due to several reasons:

1. Natural Healing Process: The stump is a remnant of the umbilical cord that connected the baby to the placenta during pregnancy. After birth, the cord is clamped and cut, leaving behind a small stump. This stump naturally goes through a healing and drying process, which may cause it to appear slightly elevated or protruding.

2. Size of the Umbilical Ring: The umbilical ring, which is the opening in the abdominal wall where the umbilical cord entered, is typically larger in newborns. As a result, the stump may protrude more prominently, especially when the baby's abdominal muscles are relaxed or when lying down.

3. Umbilical Hernia: In some cases, the umbilical stump protrudes due to an umbilical hernia. This occurs when a small part of the intestine pushes through a weakened area in the abdominal wall near the navel. It's a common condition in newborns and infants and usually resolves on its own as the abdominal muscles strengthen.

It's important to note that the protruding stump is usually a normal part of the healing process. However, if you notice any signs of infection, such as redness, swelling, discharge, or a foul smell, it's essential to consult with your doctor or healthcare provider.
