what causes hernia in newborn babies

Hernias in newborn babies occur when there is a weakness in the abdominal muscles, allowing a section of intestine to protrude through the muscle wall and create a bulge. Inguinal hernias occur in the groin area, while umbilical hernias occur around the belly button. During pregnancy, all babies have an area called the inguinal canal, which normally closes shortly before or after birth. However, in some cases, the canal doesnt fully close, allowing a loop of intestine to move into the inguinal canal through the weak spot in the belly wall and causing an inguinal hernia. Similarly, an umbilical hernia occurs when the muscles around the belly button dont fully close after birth, allowing a loop of intestine to move into the opening between the belly muscles. Hernias are most common in newborn babies, especially those who are premature or underweight. Symptoms of a hernia in a newborn baby may include a lump or swelling near the groin or belly button, pain or tenderness around the groin or lower belly, unexplained crying or fussiness, and vomiting. If a hernia becomes strangulated and blood supply is cut off, it could cause damage to the bowel or testicles, so its important to seek medical attention if you notice any concerning symptoms.
