Gastroscopy is used to investigate disorders of the stomach or throat and may be used to identify problems such as oesophageal narrowing, heartburn, Barrett’s Oesophagus, ulcers, cancer and other conditions. The procedure may also be used to treat disorders of the gut.

It is important that the stomach is empty during a Gastroscopy, therefore you will not be able to eat for six hours prior to the procedure.
Before the gastroscopy takes place you will be put under sedation or will be offered anaesthetic spray to numb your throat.

The procedure is not painful but it may feel a little uncomfortable. The endoscope will be placed in your throat. You will be asked to swallow the tube and the doctor will guide it carefully down the oesophagus and into the stomach. Any polyps or tumors will be identified and a sample of tissue (biopsy) may be taken.

You will usually undergo a Gastroscopy as an outpatient, this means you won’t have to stay overnight. Recovery takes from two to three hours after which point you will be able to leave the clinic.

It will take a little time for the effects of the sedative to wear off. You will need to have an escort to take you home and someone who is able to stay with you. You will be advised not to drive for 24 hrs.
