Frequently Asked Questions
What is the difference between an OGD and a colonoscopy?
An OGD (gastroscopy) examines the upper digestive tract — oesophagus, stomach, and the first part of the small intestine — while a colonoscopy examines the large intestine (colon and rectum). They assess different areas and are sometimes done together.
At what age should I consider colorectal screening in Singapore?
Average-risk adults are generally advised to begin colorectal cancer screening around age 50, or earlier if you have symptoms, a family history, or other risk factors. Discuss timing with your doctor.
Where can I get GI screening in Singapore?
Gastroscopy and colonoscopy are offered at public hospitals such as SGH, NUH, TTSH and CGH, and at private centres. EMIS+ can help you prepare with screening-related supplies — emis.asia.

As Singapore becomes a super-aged society in 2026, MOH continues to push early detection of colorectal cancer and gut conditions. Remember that screening colonoscopy and OGD, plus management of many chronic digestive conditions, can be supported through MediSave under the Chronic Disease Management Programme (CDMP) — with the withdrawal limits set to rise to S$700/S$1,000 from January 2027.
