A gastroscopy test, also known as an upper endoscopy, is a procedure used to examine the inside of the upper digestive tract, including the esophagus, stomach, and the first part of the small intestine (duodenum). The procedure involves inserting a thin, flexible tube called an endoscope through the mouth and into the esophagus.
During the procedure, the doctor may take tissue samples (biopsies) from the lining of the digestive tract to test for abnormalities or to check for the presence of certain conditions such as inflammation, ulcers, or cancer.
Here's what to expect during a gastroscopy test:
Preparation: You will be asked to fast for several hours before the procedure to ensure that your stomach is empty. You may also be asked to avoid certain medications that can affect blood clotting.
Anesthesia: You will be given a local anesthetic spray or throat lozenge to numb your throat and reduce the gag reflex. You may also be given a sedative to help you relax during the procedure.
Procedure: You will lie on your side or back on an exam table, and the doctor will gently insert the endoscope through your mouth and into your esophagus. You may feel some pressure or discomfort as the scope is passed down your throat, but the procedure should not be painful. The doctor will use the scope to examine the inside of your digestive tract and may take tissue samples if necessary.
Recovery: After the procedure, you will be observed for a short time to ensure that the sedative has worn off and that you are not experiencing any complications. You may feel a bit groggy or have a sore throat for a few hours after the procedure, but most people are able to return to their normal activities within a day.
Gastroscopy is a safe and routine procedure, but like any medical procedure, there are some risks, including bleeding, infection, and perforation (a tear or hole in the digestive tract). Your doctor will discuss these risks with you before the procedure and answer any questions you may have.
This test involves using a flexible tube with a camera to examine the inside of a person's stomach and intestines. It may be recommended for people who have symptoms such as abdominal pain, nausea, or difficulty swallowing, or who have risk factors for gastrointestinal diseases such as cancer or ulcers.
It can take up to a week to receive the report.
This test requires medical equipment and must be performed at diagnostic centres only. It cannot be done from home.
Fasting is usually required for this test, typically for at least 6-8 hours.
