Here’s what a few of them had to say
Endoscopy is a commonly used medical test that helps doctors examine the inside of your digestive system without the need for surgery. It’s typically performed to investigate symptoms such as abdominal pain, persistent nausea, bleeding, or swallowing difficulties. The test uses a long, flexible tube fitted with a light and camera, allowing the specialist to view real-time images of your oesophagus, stomach or bowel. If you’re wondering what is the procedure for an endoscopy, this page explains the entire process, from the day before your appointment through to the recovery phase, so you know what to expect and how to prepare with confidence.
How should you prepare for an endoscopy?
- Fasting requirements before the test – You’ll likely be asked to avoid eating or drinking for six to eight hours prior to the procedure. This ensures the stomach is empty, which provides a clear view during the examination and reduces the risk of vomiting under sedation.
- Reviewing and adjusting your medications – Some medications may interfere with the procedure or its results. For example, blood thinners can increase bleeding risks if a biopsy is taken. Your doctor may advise stopping or adjusting these medications a few days beforehand.
- Arranging support for transport – Because sedation is often used to make the procedure more comfortable, you won’t be allowed to drive yourself home. Make sure to have a loved one available to pick you up and stay with you for the first few hours post-procedure.
- Discussing your medical history – Your doctor will ask about any past medical issues that might affect the procedure or sedation. This includes allergies, heart or lung conditions, and previous surgeries. Being thorough during this step can help minimise any risks.
What happens when you arrive at the clinic or hospital?
- Checking in and providing consent – Once you arrive, you’ll go through an intake process where you confirm your identity, review your medical information, and sign a consent form. This form outlines the risks and allows the team to perform the endoscopy.
- Changing into a hospital gown – You’ll be asked to change into a hospital gown, and personal items like dentures, glasses, or jewellery will need to be removed. This ensures the area remains sterile and avoids interfering with the medical equipment.
- Initial vital checks and IV line insertion – Before the procedure begins, a nurse will measure your heart rate, oxygen levels, and blood pressure. They will then insert a cannula into your arm or hand to allow for sedation medication to be administered safely.
- A final conversation with the specialist – Just before the test, your doctor will meet with you again to answer any remaining questions and explain what to expect. This is a good time to clarify any last concerns about what is the procedure for an endoscopy.

What happens during the endoscopy itself?
- Administration of sedation and continuous monitoring – You’ll be made comfortable with mild sedation, which keeps you relaxed and drowsy without putting you fully to sleep. Your vital signs are closely monitored by the doctor throughout the process to ensure your safety.
- Insertion of the endoscope – Depending on the type of endoscopy, the camera tube is gently inserted through the mouth for upper endoscopy or through the rectum for lower endoscopy. A lubricant or anaesthetic spray may be used to ease discomfort.
- Real-time video examination of the digestive tract – The doctor will slowly manoeuvre the scope while watching the video feed. This allows a clear view of your oesophagus, stomach lining or bowel walls, and helps detect any abnormalities such as inflammation or tumours.
- Taking biopsies or performing treatments – If needed, tiny tools can be passed through the scope to collect tissue samples or treat minor issues like bleeding. This means you won’t need a second procedure, and it can often lead to faster diagnosis and recovery.
What happens after the procedure is complete?
- Waking up in the recovery area – Once the scope is removed, you’ll be taken to a quiet recovery room where nurses will monitor you as the sedation wears off. It’s common to feel a bit groggy or sleepy for a short time.
- Final checks and early results – Your care team will make sure you’re stable, and your doctor may briefly explain any visible findings. If biopsies were taken, those results usually take a few days to come back from the lab.
- Discharge and return home – Most patients are allowed to go home the same day. However, due to lingering drowsiness, it’s important not to drive, drink alcohol or make any significant decisions until the next day.
- Clear post-procedure instructions – You’ll receive written aftercare directions outlining when to eat, how to take your medications, and which symptoms to watch out for. This step is crucial to ensure safe and smooth recovery.

When should you contact your doctor after the procedure?
- Persistent or intense abdominal pain – Some mild cramping or bloating is expected, but severe pain could be a sign of something more serious, such as a perforation or complication from a biopsy.
- Unusual bleeding or vomiting – It’s not uncommon to see a little blood. However, large amounts of blood in your stool or vomit is concerning and should prompt immediate medical attention.
- Signs of infection, like fever or chills – If your temperature rises above normal, or you begin to feel unwell with shivering, this could suggest an infection and must be checked by your doctor.
- Breathing or swallowing difficulties – Complications can sometimes cause issues with breathing or swallowing, particularly after an upper endoscopy. These symptoms should never be ignored.
Still unsure about what to expect?
If you’ve been scheduled for this test and find yourself wondering what is the procedure for an endoscopy, it’s completely normal to feel uncertain. Medical procedures can bring up questions or concerns, especially if it’s your first time. The good news is that an endoscopy is a well-established and generally safe way to investigate a wide range of digestive symptoms.
Understanding what is the procedure for an endoscopy ahead of time can ease a lot of anxiety. From preparation to recovery, each step is designed to prioritise your comfort, safety, and overall well-being. With sedation and a skilled team guiding the process, most people complete the procedure without discomfort or complications.
You don’t need to navigate it on your own. Speaking to your doctor about the process and what to expect in your specific case can make a big difference. They’ll help you prepare, walk you through recovery, and explain any next steps based on your results.

FAQs
Can I take my regular medications on the morning of the test?
It depends on the medication. Some may need to be paused or timed differently. Always check with your doctor in advance of the procedure.
Do I need someone to stay with me at home afterwards?
Yes. Because sedation can impair your alertness for several hours, having someone with you until the next day is strongly recommended for safety.
Is it possible to undergo the procedure without sedation?
In some cases, yes. If you prefer not to be sedated, talk with your doctor about options like local anaesthetic sprays or minimal sedation.
Will the doctor remove anything during the test?
If a polyp, foreign object or area of concern is found, the doctor may remove or treat it during the same session to avoid the need for a second procedure.
