Postoperative bloating may be caused by the lack of recovery of peristalsis after surgery, which can be relieved on its own after 1-2 days. It may also be related to water and electrolyte disorders, peritonitis, intestinal obstruction and other factors, if you are not feeling well, it is recommended to consult your doctor in time. After surgery, due to traumatic stimulation, resulting in gastrointestinal function is inhibited, gastrointestinal peristalsis is slow, the intestinal tube of the accumulated gas can not be discharged in a timely manner, the symptoms of abdominal distension will occur. Usually, after 1-2 days of rest and successful evacuation of gas, it will gradually improve and does not require special treatment. However, we should be careful about the postoperative water and electrolyte disorders. If there is a lack of potassium, intestinal paralysis may occur, causing abdominal distension, which can be relieved after potassium supplementation. If the postoperative care is not proper, infection causes peritonitis, which may further cause mechanical intestinal obstruction, leading to abdominal distension. This situation needs to be treated with enema, decompression and other measures, and timely treatment is recommended.
