Generally speaking, the stomach will be bloated for about 7 days after hernia surgery, but the exact time varies from person to person. People with hernia after surgery, due to the stimulation of anesthesia in the operation and the impact of intraoperative operation, will make the clinical manifestation of abdominal distension after surgery, generally in about 7 days after the operation abdominal distension will be relieved, but due to the patient’s condition is different, different physique, whether the operation is smooth and other reasons, the specific time will also be different. For people with milder conditions (e.g., easily recurring hernia) and better physical condition, the symptoms of abdominal distension will be relieved in about one week after surgery, while for patients with more severe conditions (e.g., strangulated hernia may cause intestinal necrosis, resulting in diffuse peritonitis) and poorer physical condition, the recovery of abdominal distension symptoms after the surgery will take more time. Those with severe symptoms described after surgery are advised to seek prompt medical attention and early treatment.
