Frequently asked questions
Why am I constipated after surgery?
It is one of the most common after-effects. Opioid painkillers slow the gut right down, and surgery, anaesthetic, lying still, eating and drinking less, and a change of routine all add up. It usually settles as you get moving and eating again.
How many days without a bowel movement is too long?
Going 2-3 days without a bowel movement is common and usually not an emergency on its own, especially early after surgery. But if it stretches longer, or you also feel sick, are vomiting, have a swollen painful belly, or are passing no wind/gas at all, contact your team that day.
Should I take a laxative after surgery?
If you are on opioid painkillers, taking a gentle laxative early (before you are badly blocked up) is often recommended rather than waiting. Many surgical teams send you home with one. Always confirm with your own team or the pharmacist and follow the leaflet that came with it.
What are the danger signs of a blocked bowel?
Seek urgent help if you have no bowel movement together with vomiting, a swollen hard painful belly, or you are passing no wind/gas at all. These can signal a blocked bowel or ileus and need to be checked the same day.
