It is abnormal for there to be movement of gas within an umbilical hernia. This could potentially indicate that the contents of the hernia include a part of the intestine. When excessive intestine is present within the hernial sac of an umbilical hernia, it can easily lead to the movement of gas as it moves through the intestine. This condition is relatively common in clinical settings, and it is also used as a symptom to diagnose the possibility of an umbilical hernia. Therefore, when there is movement of gas observed in an umbilical hernia, it is crucial to reposition the hernia back into place using massage and other standard techniques to avoid prolonged entrapment of the intestine, which can lead to ischemic necrosis and the possible formation of an incarcerated hernia. This condition should be actively treated to prevent complications.
