What are some reasons of constipation after surgery?

Constipation after surgery is a common problem. There are several reasons why constipation may occur after surgery, including:

1. Reduced mobility: Following surgery, patients may be less mobile or confined to bed. Reduced physical activity can slow down the digestive process and make it more difficult to pass stool.

   • Medications: Certain medications, such as pain relievers (opioids) and anticholinergics, can cause constipation as a side effect.

2. Changes in diet: During the period immediately following surgery, patients may have a restricted diet or may not be able to eat their usual foods. Diet changes can upset the normal balance of the digestive system and cause constipation.
3. Anesthesia: The use of anesthesia during surgery can temporarily slow down the digestive process and lead to constipation.
4. Dehydration: After surgery, patients may experience dehydration, which can exacerbate constipation by hardening stool and making it more difficult to pass.
5. Nerve damage: In some cases, surgery, especially pelvic surgery, can damage nerves that control bowel movements leading to difficulty in passing stool.
6. Pain: Post-surgical pain or discomfort can make it difficult and uncomfortable to use the bathroom.
