How long does constipation last after general anesthesia?

Constipation following general anesthesia may last for 2–3 days. However, individual patient variability is considerable, and the actual duration may differ.

Constipation after general anesthesia surgery is primarily associated with the use of anesthetic agents, as well as postoperative bed rest and dietary factors. Certain anesthetics may suppress intestinal motility, leading to accumulation of food within the gastrointestinal tract. Additionally, patients typically remain bedridden for a period after surgery, further slowing intestinal peristalsis. This prolongs fecal retention time in the colon, allowing excessive water absorption by the intestinal mucosa and resulting in hard, dry stools—thus causing constipation. Generally, constipation following general anesthesia surgery lasts about 2–3 days. However, if the surgical procedure is extensive and requires prolonged bed rest, or if the patient neglects dietary considerations—such as consuming poorly digestible foods—the duration of constipation may be extended.

Following general anesthesia surgery, patients are generally advised to maintain a liquid or soft diet and avoid high-fiber foods to prevent overburdening the gastrointestinal tract and reduce the risk of indigestion or constipation.
