Wearing a truss or binder may temporarily alleviate symptoms but will not cure the hernia. Only surgery corrects the defect in the belly wall.
Once a hernia has developed it will tend to enlarge and cause discomfort. If a loop of bowel gets caught in the hernia it may become obstructed or its blood supply may be cut off. This could then become a life-threatening situation. Since hernias can be repaired effectively and with minimal risk most surgeons therefore recommend that hernias be repaired when diagnosed unless there are other serious medical problems.
