Gastroscopy (OGD) in Singapore: Specialist Upper GI Evaluation
Accurate Diagnosis & Early Detection for Stomach, Acid Reflux & Digestive Symptoms
A Gastroscopy — also known as an OGD (Oesophago-Gastro-Duodenoscopy) —is a quick, routine day-surgery procedure that provides direct visualization of your upper digestive system. Performed using a ultra-thin, flexible camera tube, it allows our surgeons to inspect, biopsy, and treat mucosal abnormalities in a single session.
When should you get a gastroscopy?
You should consider an upper endoscopy if you experience persistent upper digestive symptoms, or as part of cancer screening.
1. Investigating Warning Symptoms
Persistent Upper Abdominal Pain or Bloating:
Frequent indigestion that doesn’t resolve with antacids.
Chronic Acid Reflux / GERD:
Long-standing heartburn, regurgitation, or chest discomfort.
Difficulty or Painful Swallowing:
Feeling like food gets stuck in your chest.
Unexplained Weight Loss
or Loss of Appetite
Signs of GI Bleeding:
Vomiting blood, dark/tarry stools, or unexplained iron-deficiency anemia.
2. Early Stomach Cancer Screening
Stomach (gastric) cancer is among the top cancers in Singapore and often remains silent in its early stages. A gastroscopy is the gold standard for detecting pre-cancerous lesions, H. pylori bacterial infections, and stomach ulcers before they progress.
Combined Screening: Many patients choose a Double Scope (Gastroscopy + Colonoscopy) in a single session to thoroughly evaluate both the upper and lower GI tracts under one period of sedation.
What Happens During the Procedure?
A gastroscopy is safe, painless, and completed within 10 to 15 minutes.
