Gastroscopy or Upper GI Endoscopy

What is a Gastroscopy?

A gastroscopy (you may know it as an endoscopy) is a procedure that uses a thin, flexible tube (endoscope) to examine the oesophagus, stomach, and upper part of the small intestine (duodenum).

The endoscope has a light and small camera at one end, that sends images directly to a screen for the endoscopist to review.

An Upper GI procedure typically takes less than 15 minutes, and you’ll usually be able to go home the same day.

Your Clarity consultant will explain the procedure and be on hand to answer any questions you may have.

Your comfort is essential for the successful completion of the procedure. To ensure your comfort, your throat will be numbed with a local anaesthetic spray before the procedure. You also have the option of receiving a sedative if you prefer, please note that you will still be awake but the sedative will make you drowsy and reduce your awareness about what’s happening. If you choose to be sedated, you must be accompanied by a responsible adult for 24 hours. During this time, you should avoid work, operating machinery, and making significant life or financial decisions.

Your Clarity consultant will discuss all the options available to you, ensuring your receive a personalised care plan.

Preparing for a Gastroscopy

While you await your gastroscopy, it’s important to maintain a healthy diet and avoid anything that aggravates your symptoms.

  • Lifestyle Changes: Reducing alcohol consumption and quitting smoking can significantly improve symptoms of many conditions affecting the oesophagus and stomach.
  • Medication: Unless advised otherwise by your doctor, avoid over-the-counter anti-inflammatory medications such as ibuprofen.

Pre-Procedure Instructions

Once your gastroscopy appointment is scheduled, we will provide you with specific instructions on how to prepare.

  • Fasting: You will be required to fast for at least 6 hours before the procedure. Small sips of water are generally permitted up to two hours before your appointment. This fasting period ensures an empty stomach, allowing for a clear view during the examination.
  • Blood Thinners: If you are taking blood-thinning medications such as warfarin or clopidogrel, you may need to temporarily discontinue them a few days prior to the endoscopy to minimize the risk of bleeding. Crucially, do not stop any prescribed medication without explicit instructions from your GP or specialist.

Remember: These instructions are general guidelines. Please follow the specific instructions provided by your healthcare provider for your individual case.

Recovery from a Gastroscopy

Following your procedure, you will be given time to recover from the procedure in a comfortable setting.

If you had throat spray: You will be offered a cold drink once the numbness in your throat has subsided.

If you received sedation:

  • The initial effects of sedation typically wear off within 30 minutes. However, some individuals may feel fully alert immediately after the procedure.
  • During your recovery, our nurses will closely monitor your oxygen levels, blood pressure, and heart rate.
  • Sedation can remain in your system for up to 24 hours, and you may experience drowsiness and some memory lapses.

Important Note:

Driving Restrictions: You will not be able to drive after receiving sedation. Please arrange for someone to escort you home and supervise you for 24 hours.
