Within 24 hours of inguinal hernia surgery, patients are advised to lie flat on their backs and are not advised to sleep on their sides, after 24 hours patients are allowed to sleep on their sides as well as move freely. Inguinal hernia refers to the outward protrusion of an organ from the abdominal cavity, which is mainly due to the weakness of the abdominal wall as well as increased pressure in the abdomen. Inguinal hernia is a common surgical condition that manifests itself as a mass in the inguinal region of the patient, which appears to increase in size while standing, walking for some time, and slowly disappears after lying down. Within 24 hours after the patient’s inguinal hernia surgery, the patient’s body is relatively weak, and after the anesthetic period, it may produce pain or abdominal distension and other adverse reactions. Sleeping on the side at this time will increase the pressure on the abdomen, resulting in poor blood circulation at the surgical site, aggravating the pain at the surgical site as well as bloating, so it is recommended to lie flat within 24 hours of surgery. After 24 hours, the patient’s vital signs are stable and he can move freely, then he can sleep on his side and change his position appropriately. If there is any adverse reaction to sleeping on the side after inguinal hernia surgery, contact your doctor for examination.
