Hernia surgery is divided into hernia surgery for children and adults. Children can recover from hernia surgery in about 2-3 days and adults can recover from hernia surgery in about 7-10 days. Hernia occurs in association with reduced strength of the abdominal wall or increased pressure in the abdomen, such as chronic cough and chronic constipation. The clinical manifestation of early hernia is mild localized distension and pain, which does not affect the function of organs and has no systemic symptoms, while severe hernia is manifested by increased localized distension and pain with a feeling of falling. Usually, surgical treatment of hernia in children does not require the placement of patches, but in adults, patches need to be placed, and the incision is larger, and the stitches can be removed only about 7 days after surgery, and the recovery time is relatively long. After hernia surgery, it is important to eat a light diet, rich in protein and vitamins, and to adopt a semi-recumbent position in bed to reduce abdominal wall tension and promote wound healing. Avoid coughing hard for 1 month after surgery, and avoid strenuous exercise for 3 months to prevent the recurrence of hernia caused by the increase of intra-abdominal pressure.
