Gastroscopy is a procedure used to examine the oesophagus, stomach, and the first part of the small intestine. It helps doctors diagnose and investigate a range of digestive symptoms and conditions.
A gastroscopy allows your doctor to examine the upper digestive tract using a thin, flexible tube called an endoscope. The endoscope contains a camera that transmits images to a monitor, allowing the doctor to carefully inspect the lining of the oesophagus, stomach, and duodenum. Gastroscopy may be recommended to investigate symptoms such as persistent indigestion, abdominal pain, nausea, difficulty swallowing, or unexplained bleeding.
Before the procedure begins, a local anaesthetic spray may be applied to numb the throat. Many patients also receive sedation through an intravenous line to help them relax.
The doctor gently passes the endoscope through the mouth and down the oesophagus to examine the stomach and upper intestine.
The procedure usually takes only a short time. If necessary, small tissue samples (biopsies) can be taken during the examination for further testing.
After the procedure, you will rest in our recovery area while the sedation wears off.
Your throat may feel slightly sore or dry for a short time, which is normal. Once you are alert and comfortable, you will be able to return home.
If you have received sedation, you must arrange for someone to drive you home, as you will not be able to drive for 24 hours.
You should avoid alcohol, operating machinery, or making important decisions during this time. Most patients are able to return to their usual activities the following day.
Seek medical advice if you experience:
These symptoms are uncommon but should be assessed promptly.
Gastroscopy is considered a safe procedure, but as with any medical procedure there are small risks involved.
Possible complications include bleeding, infection, or injury to the digestive tract. Your specialist will discuss these risks with you before the procedure..
To ensure a clear view of the stomach and oesophagus, your stomach must be empty before the procedure.
You must not eat or drink anything for six hours before your gastroscopy.
