OGD (Oesophago-Gastro-Duodenoscopy), commonly known as an upper endoscopy, is a procedure where a thin, flexible tube with a camera (endoscope) is inserted through the mouth to examine the lining of the oesophagus, stomach, and the upper part of the small intestine (duodenum). This procedure helps in diagnosing conditions like acid reflux, ulcers, inflammation, bleeding, or tumours within the upper gastrointestinal tract.

Preparation for OGD:

• Fasting: Patients are usually required to avoid eating or drinking for 6–8 hours before the procedure to ensure an empty stomach, which allows for a clearer view and reduces the risk of aspiration.
• Medication Adjustments: Certain medications may need to be temporarily stopped, particularly blood thinners or antiplatelet medications, to reduce the risk of bleeding. Discuss any medications with the doctor beforehand.
• Arrival with a Companion: Patients who receive sedatives for the procedure should arrange for someone to accompany them home due to drowsiness or impaired coordination post-procedure.
• Discuss Allergies and Health Conditions: Patients should inform the medical team of any allergies, pregnancy, or other health conditions, especially respiratory issues, which could affect the procedure.
• Sedation Consent: Patients are typically asked to sign a consent form before receiving sedation, and they’ll have the option to undergo the procedure with sedation for comfort.
