This information provides guidance for individuals following an examination of the large bowel, such as a colonoscopy or flexible sigmoidoscopy. If sedation was used during the procedure, it is important to rest for the remainder of the day.
Most after‑effects are mild and may include the following:
Abdominal Discomfort
You may experience some abdominal discomfort caused by trapped wind. This should settle quickly. Passing wind can help ease this discomfort.
You may also take mild pain relief such as paracetamol if required. Peppermint oil preparations or peppermint tea can also help.
Contact your GP if you develop severe abdominal pain or vomiting.
Discomfort at the Injection Site
Mild discomfort in the arm where sedation was administered is common. A cold ice pack may help.
If the injection site becomes increasingly sore, red, swollen, or tender, please contact your GP.
Bleeding
If a biopsy was taken or a polyp removed, you may notice small traces of blood from your rectum. This is normal.
However, contact your GP if:
- The bleeding persists or becomes heavier
- Your bowel habits do not return to normal within 2–3 days
Seek urgent medical help if you suddenly pass a large amount of fresh blood, feel faint, pale, or sweaty. Contact:
- Your GP, or
- NHS 24 on 111
If you are unable to get through and symptoms are severe, go to the Emergency Department at Forth Valley Royal Hospital.
General Advice
- You may resume your normal prescription medication.
- You may return to your usual diet, unless advised otherwise.
- If you received sedation:
Do NOT drive, work, operate machinery, drink alcohol, or sign legal documents for 24 hours, as your memory and coordination may be affected.
Further advice will be given by your GP or at your next clinic appointment (if arranged). A copy of your procedure report will be sent to your GP within 10–14 days.
