Hernias in children require surgery even if they are no longer painful. A hernia is usually a weak point defect as well as a gap in the body where an organ or tissue leaves its normal anatomical position in the body, either through congenital or acquired formation. Hernias are usually caused by excessive abdominal obesity, straining to defecate, pregnancy in women as well as excessive straining and may present with symptoms such as constipation, loss of appetite, restlessness, lumps as well as pain. Young children under 1 year of age have the potential to heal on their own because of the underdevelopment of the abdominal wall. Hernias in children over 1 year of age with no specific symptoms are also treated with elective surgery. If left untreated for a long period of time, the condition may gradually worsen, making them prone to intestinal obstruction, intestinal necrosis, and even peritonitis and other discomforts. Hernias can be treated with traditional hernia repair, tension-free hernia repair and other surgical procedures under the guidance of a doctor. If a small child develops a hernia, he or she should go to the hospital in time to avoid delays and adverse consequences.
