This page gives you information on care following your gastroscopy.


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 the following:

  • A bloated, windy feeling – moving around may help to relieve this.
  • A sore throat for a short time after the procedure. This is normal and should pass within 2 days.

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.

Seeking advice?

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

  • Severe pain in the neck, chest or abdomen
  • Vomiting blood or bowel motion turns black
  • Abdominal pain and/or bloating
  • High temperature (fever) or you feel generally unwell.

If you have any concerns please contact one of the following for advice:

  • Endoscopy Unit where you were seen
