Hernia includes many diseases, but what people call hernia in children mainly refers to “inguinal hernia”. Many people think that only boys get hernia, but in fact, girls also get hernia, but the number of incidences is less, and the ratio of boys to girls is about 3:1. When a girl cries or exerts herself on her abdomen, a reversible swelling, about the size of a date palm or a lantern, appears on the upper part of the labia majora, she must be alerted to the possibility of hernia and go to the hospital immediately, and once diagnosed, surgery is needed, and there is no restriction on the age of surgery. However, most doctors advocate the implementation of surgery after 2-3 months. There is no other way to cure hernia without surgery, and when a child cries, it is easy to cause hernias to become embedded, i.e. the pubic mass cannot be retracted into the abdominal cavity. If the impaction lasts longer than 24 hours, necrosis of the intestinal canal or ovaries may occur, suggesting possible intestinal necrosis, which should be treated immediately with emergency surgery. How to prevent hernia impaction? Parents must pay attention to several preventive measures: 1. Avoid catching cold and flu and actively treat respiratory tract infections. 2. Prevent constipation: eat more vegetables and fruits, and develop the habit of regular bowel movements. 3, avoid and reduce unwarranted crying. Finally, we must remind you that surgery is the fundamental prevention method.
