Procedure Overview
An Upper GI Endoscopy (Esophagogastroduodenoscopy / EGD) is a diagnostic and therapeutic procedure that allows the doctor to view the lining of the upper gastrointestinal tract (esophagus, stomach, and duodenum) using a flexible tube with a high-resolution camera. Sedation or throat spray may be offered. Endoscopy may help investigate heartburn, stomach ulcers, H. pylori infection, celiac disease, and gastrointestinal bleeding.
Clinical Indications for Upper GI Endoscopy (EGD)
- Chronic heartburn, severe acid reflux, or swallowing difficulty (dysphagia)
- Persistent upper abdominal pain, nausea, or unexplained vomiting
- Unexplained anemia, weight loss, or positive celiac disease blood test
- Evaluation of gastrointestinal bleeding or dark stools
Key Benefits & Advantages
Required Patient Preparation
What to Expect During the Procedure
- Throat spray or sedation may be offered after assessment.
- The endoscope is gently guided down the throat while your breathing is fully monitored.
- The complete procedure takes 15–20 minutes.
- Recovery and discharge depend on sedation and the treatment performed.
Risks, alternatives and recovery
The team should explain alternatives and risks, including bleeding, perforation, infection and reactions to sedation. ERCP also carries a risk of pancreatitis. Risk depends on your health and the treatment performed.
Follow your own written preparation and discharge instructions. Do not change blood thinners or diabetes medicines without advice. After sedation, arrange an escort and avoid driving until the clinical team says it is safe.
When should I get urgent help?
Seek urgent care for severe or worsening pain, fever, breathing difficulty, vomiting blood or significant bleeding after a procedure. Procedure time, discharge and results vary; contact the treating team for your plan.
Frequently asked questions
Is endoscopy painful?
Throat spray or sedation may reduce discomfort, but the experience varies. Discuss the sedation plan, risks and recovery instructions with the endoscopy team; complete absence of discomfort cannot be promised.
