This page gives you information on care following your colonoscopy/flexible sigmoidoscopy.

When can I eat and drink?

You can eat and drink normally after discharge; although we do recommend a lighter diet for today.

Medication

You can take your usual prescribed medications when they are next due unless otherwise stated by the Endoscopist or discharging nurse. For blood thinning medications (anticoagulants) separate advice will be given.

After effects

You may experience a bloated, windy feeling – moving around may help to relieve this.

If we have removed a polyp, you may bleed slightly after the procedure, this is not unusual.

What happens next?

  • A report will be sent to your GP.
  • The results of the test and any specimens taken are sent directly to your GP. This can take up to 5 weeks.
  • If a consultant follow up is needed you will receive an appointment letter in the post.
  • If a repeat procedure is needed your medical notes will be reviewed by an Endoscopist before you are due to attend. This is because the criteria for repeating procedures may change or be altered as National Guidelines are reviewed and updated. If it is felt that your procedure is no longer required, we will send you a letter in the post.

A member of the nursing team will have explained to you what has been done today and any further tests that you may need.

When to seek advice

Serious side effects are rare. However, if any of the following occur within 48 hours after your colonoscopy/flexible sigmoidoscopy please contact the Endoscopy Unit where you had your procedure.

  • Severe pain in the chest or abdomen.
  • Bleeding from the bowel (bottom) or bowel motion turns black.
  • Abdominal pain and/or bloating.
  • High temperature (fever) or you feel generally unwell.
  • Disorientation (feeling lost or confused).

If you have been given Buscopan® to relax your bowel during the procedure please seek urgent medical advice if you experience any of the following:

  • Painful red eye with loss of vision.
  • Blurred, misty or foggy vision.
  • Nausea and/or vomiting.
  • Unable to pass urine.

Results

Please contact your GP or consultant directly for your test results as these are not disclosed to Endoscopy.
