Gastroscopy
What is a Gastroscopy?
Gastroscopy, also known as upper endoscopy, is a procedure that allows doctors to examine the lining of the esophagus, stomach, and the first part of the small intestine (duodenum) using a flexible tube equipped with a camera called a gastroscope. It is used to detect ulcers, inflammation, tumors, and other gastrointestinal conditions.
What qualifies you for a Gastroscopy?
You may need a gastroscopy if you:
– Experience persistent heartburn, acid reflux, or difficulty swallowing
– Have unexplained upper abdominal pain or nausea
– Suspect bleeding in the upper gastrointestinal tract
– Need follow-up for previous abnormal findings
Advantages
– Direct visualization of the upper GI tract
– Ability to perform biopsies or remove small growths during the procedure
– Minimally invasive with low complication rates
– Early detection of gastrointestinal disorders and cancers
– Quick recovery and usually outpatient
How it works ?
The procedure is performed under sedation. The gastroscope is gently inserted through the mouth and advanced through the esophagus, stomach, and duodenum. The camera transmits live images to a monitor, allowing the doctor to examine the lining and perform biopsies if needed. Gastroscopy usually takes 10–30 minutes.

– Arrange for someone to drive you home after sedation
Recovery and post-care
– Patients can usually go home the same day
– Mild sore throat or bloating may occur
