Gastroscopy is the procedure where a thin flexible scope with a light and camera at its tip is inserted through the mouth to investigate digestive signs and symptoms such as nausea, vomiting, abdominal pain, difficulty in swallowing and gastrointestinal bleeding in the upper gastro-intestinal tract.
You will need to be fasted for at least 6 hours to ensure your stomach is empty for the procedure.
Inform your doctor of any pre-existing chronic conditions you may have, such as diabetes, heart disease or high blood pressure, that require regular medications,
Your doctor may instruct you to stop medication such as blood thinners that may increase your risk of bleeding, a few days before the procedure.
Your breathing, heart rate and blood pressure will be monitored throughout the procedure.
Sedation is usually given as well as an anaesthetic spray in your mouth to numb the throat.
Your doctor will insert an endoscope into your mouth. A tiny camera at the tip of the scope will transmit images to a video monitor. This enables the doctor to look for abnormalities in your upper digestive tract. Special surgical tools will pass through the endoscope to collect tissue samples or remove polyps.
You'll be taken to a recovery area to rest after your endoscopy and your vital signs will be closely monitored until the sedation wears off.
You should not drive after the procedure and may experience some mild discomfort like bloating, cramps or a sore throat, which should improve with time.
You will be given a follow up appointment. Depending on the findings, your doctor will prescribe the appropriate treatment. Should you feel unwell after the scope, contact your doctor immediately or call our 24-Hour Medical Urgency Clinic.
