What is this test?
Gastroscopy, also known as upper endoscopy, is a minimally invasive diagnostic procedure that uses a thin, flexible tube equipped with a high-resolution camera and light to directly visualize the lining of the esophagus, stomach, and the first part of the small intestine (duodenum). This allows for detailed examination of the upper gastrointestinal (GI) tract to detect abnormalities that might not be visible with other imaging techniques.
What is it used for?

• Diagnosing causes of upper abdominal pain, persistent heartburn, nausea, or unexplained vomiting
• Detecting ulcers, inflammation (gastritis or esophagitis), tumors, polyps, or bleeding sources
• Investigating symptoms such as difficulty swallowing, unexplained weight loss, or anemia
• Taking biopsies (small tissue samples) for further laboratory analysis, including testing for infections like Helicobacter pylori
• Evaluating structural abnormalities like strictures, hiatal hernias, or varices

Who should get this test?

• Patients experiencing persistent upper GI symptoms including abdominal pain, acid reflux, difficulty swallowing, or gastrointestinal bleeding
• Individuals with a history or suspicion of peptic ulcer disease, Barrett’s esophagus, or stomach cancer
• Those requiring follow-up on previously detected abnormalities in the upper digestive tract
• Patients with unexplained anemia or weight loss where a GI source is suspected

Preparation Required:

• Fasting for 6 to 8 hours prior to the procedure to ensure an empty stomach and clear view
• Arrange for sedation or anesthesia, as the test is often performed under mild sedation to reduce discomfort
• Inform your healthcare provider of any medications, allergies, or medical conditions beforehand
• Arrange transportation home after the procedure due to sedation effects

How is the procedure performed?
During the gastroscopy, the patient lies on their side, and a local anesthetic may be sprayed into the throat to minimize gagging. A thin, flexible endoscope is gently inserted through the mouth and guided down the esophagus into the stomach and duodenum. The camera transmits real-time images to a monitor, allowing the physician to carefully inspect the mucosal surfaces. If necessary, small instruments can be passed through the scope to take biopsies or treat certain abnormalities. The entire procedure typically lasts between 15 and 30 minutes.
Risks & Safety:
Gastroscopy is generally safe and well-tolerated. Mild side effects include throat soreness or bloating afterward. Risks are rare but can include complications related to sedation, minor bleeding especially if biopsies are taken, or very rarely, perforation (a small tear in the GI lining). Your medical team will discuss these risks beforehand and monitor you closely during and after the procedure.
Results:
The endoscopist will provide a detailed report on visual findings including any ulcers, inflammation, tumors, or bleeding sites. Biopsy samples, if taken, are sent to pathology for analysis, with results usually available within a few days. Based on findings, your doctor will recommend appropriate treatment or further testing.
Short Statement:
A minimally invasive procedure using a flexible camera tube to directly examine the esophagus, stomach, and upper small intestine, identifying ulcers, inflammation, tumors, or bleeding to guide diagnosis and treatment.
