Gastroscopy

Overview

‍
Gastroscopy, also known as upper endoscopy, is a minimally invasive procedure used to examine the esophagus, stomach, and duodenum (upper small intestine). It is performed using a thin, flexible tube with a camera (endoscope), which is inserted through the mouth to detect abnormalities such as ulcers, inflammation, infections, or tumors.

‍

This procedure helps diagnose and sometimes treat conditions like acid reflux (GERD), gastritis, peptic ulcers, Barrett’s esophagus, and stomach cancer. It can also be used for biopsies, removing polyps, or stopping internal bleeding in the digestive tract.

When is Gastroscopy Recommended?

‍

Gastroscopy is recommended for individuals experiencing persistent digestive symptoms such as heartburn, difficulty swallowing, nausea, vomiting, unexplained weight loss, or stomach pain. It is necessary when doctors need to investigate bleeding, tumors, chronic reflux, or suspected infections in the upper digestive tract.

‍

This procedure is also commonly used for routine screening in high-risk patients, such as those with a family history of stomach cancer, chronic acid reflux, or H. pylori infection.

Procedure Details

‍

Gastroscopy is a quick and safe outpatient procedure used to diagnose and treat upper digestive tract issues.

A mild sedative or anesthesia is administered for patient comfort.

The endoscope is gently inserted through the mouth into the esophagus and stomach.

The digestive tract is examined for abnormalities.

If necessary, biopsies, tissue removal, or minor treatments are performed.

The endoscope is removed, and the patient is monitored before discharge.

Recovery

‍

Recovery after gastroscopy is fast, with most patients able to go home the same day. Mild throat discomfort, bloating, or drowsiness from sedation may occur but typically resolves within a few hours.

We provide post-procedure care instructions, including temporary dietary restrictions and symptom monitoring. Most patients can resume normal activities within 24 hours, although results from biopsies may take a few days.
