How to Prepare for an Endoscopy?

Before the Procedure;

Your doctor will give you specific instructions to prepare for the procedure, based on your overall health, the type of endoscopy, the type of anesthesia used, and your digestive system’s condition.


For most endoscopic procedures, a person will need to fast for about 6-12 hours before the test. Fasting helps to remove food from the digestive tract, enabling the doctor to see it more clearly during the procedure.


Some endoscopies require the use of local anesthesia to reduce pain, while others require general anesthesia. Sedatives are also used to help reduce anxiety and keep you relaxed.

Tell the doctor about any existing medical conditions and medications you may be taking, including non-prescription drugs, vitamins, and herbal supplements. The doctor may instruct you to stop using certain drugs beforehand.

During the Procedure:

You will usually lie down on your side with your mouth open, or on your back if it’s a colonoscopy, while an endoscope is passed through your mouth or anus.

You will be given a chance to breathe normally during the test, and the doctor will closely monitor your breathing, pulse, and blood pressure.

After the Procedure;

You will be moved to a recovery area to rest and will be monitored carefully by the medical team. You may experience some mild discomfort, such as bloating and gas, after the procedure, which is entirely normal. These symptoms usually improve as the day wears on.


Endoscopies are essential in detecting and treating many medical conditions affecting different parts of the body. Preparing well for the procedure is critical, and patients need to follow the doctor’s orders concerning diet, medications, and fasting instructions.
