What is an Upper GI Endoscopy?
- A procedure to examine the esophagus, stomach, and duodenum (upper small intestine) using a flexible endoscope (camera).
- Also called a gastroscopy, OGD, or simply endoscopy.
Why is it Done?
To diagnose symptoms such as:
- Difficulty swallowing, bloating, diarrhea, unexplained weight loss.
- Nausea, vomiting, abdominal pain.
- To check for anemia or take biopsies for further analysis.
Preparation Before the Procedure
- Medication: Inform healthcare providers at least 10 days prior if taking blood thinners or diabetic medication.
- Fasting: Do not eat for six hours before the procedure; only small sips of water up to two hours before.
Procedure Details
- Takes around 10 minutes.
- A cannula (small tube) may be inserted in the hand for medication.
- Sedation or local anesthetic throat spray may be used for comfort.
- The endoscope is inserted through the mouth and down the esophagus into the stomach and duodenum.
- Air may be blown into the stomach for better visibility.
- Biopsies or images may be taken during the procedure.
Risks and Possible Complications
Minor risks: Temporary sore throat, bloating, or discomfort.
Serious but rare risks:
- Perforation (1 in 2,000 cases) – a hole in the esophagus, stomach, or intestine.
- Heavy bleeding from biopsy sites.
- Allergic reaction to medication or sedation.
- Heart attack or stroke (very rare, 1 in 25,000 cases).
After the Procedure
- Patients who did not receive sedation can usually go home soon after.
- Those who had sedation need monitoring for about an hour before being discharged.
- Temporary bloating is common.
- Biopsy results may take time; follow-up with the healthcare team.
- For 24 hours after sedation:
- No driving, operating machinery, signing documents, or drinking alcohol.
- A responsible adult should accompany the patient home.
- Return to work the next day unless advised otherwise.
