An umbilical hernia occurs when a portion of the intestine or fatty tissue pushes through a weak spot in the abdominal muscles near the navel (belly button). This condition is common in infants but can also affect adults, especially those who are overweight or pregnant. Symptoms may include a noticeable bulge in the abdomen, which can become more prominent when coughing or straining. Treatment for an umbilical hernia often involves surgery, especially if it causes pain or complications. In many cases, hernias in infants may close on their own as they grow. Regular check-ups with a healthcare provider can help monitor the condition.
