At Upper Hill Gastroenterology, we specialize in performing OesophagoGastroDuodenoscopy (OGD)—a safe and highly effective procedure to diagnose and treat conditions affecting the upper digestive tract. With our skilled team and state-of-the-art technology, we aim to provide accurate diagnostics and expert care in a comfortable environment.
What is OGD?
OesophagoGastroDuodenoscopy, also known as upper endoscopy, is a minimally invasive procedure used to examine the:
- Esophagus (food pipe)
- Stomach
- Duodenum (the first part of the small intestine)
During the procedure, a thin, flexible tube with a camera (endoscope) is inserted through the mouth to provide a detailed view of the upper digestive tract. OGD helps detect abnormalities, diagnose symptoms, and even perform minor treatments, such as removing polyps or taking tissue samples (biopsies).

Why is OGD Performed?
Your doctor may recommend OGD to:
- Investigate symptoms such as:
- Persistent heartburn or acid reflux
- Difficulty swallowing (dysphagia)
- Upper abdominal pain
- Unexplained nausea or vomiting
- Gastrointestinal bleeding (vomiting blood or black stools)
- Unexplained weight loss
- Diagnose conditions, including:
- Gastritis or ulcers
- Esophagitis
- Celiac disease
- Tumors or cancers of the upper digestive tract
- Treat certain conditions, such as:
- Removing foreign objects
- Stopping active bleeding
- Dilating narrowed areas (strictures)
What to Expect During OGD
1. Preparation
- Fasting: You’ll need to avoid eating or drinking for 6–8 hours before the procedure.
- Medication Adjustments: Inform your doctor about medications you’re taking, as some may need to be paused.
2. Procedure
- The procedure is performed under sedation or local anesthetic spray to ensure your comfort.
- The endoscope is gently guided through your mouth into the digestive tract.
- The camera transmits high-resolution images to a monitor, allowing the doctor to inspect the area thoroughly.
- If necessary, biopsies can be taken or minor treatments performed during the same session.
3. Post-Procedure
- After the procedure, you’ll be monitored until the sedation wears off.
- You may experience a mild sore throat or bloating, which typically resolves quickly.
- Your doctor will discuss the findings and next steps, including follow-up care if needed.
