Shedding Light on Colonoscopy: A Guide for Singapore Residents
4 min read

Colonoscopy, often shrouded in a bit of mystery, is a crucial tool for early detection and treatment of colorectal cancer, a significant health concern in Singapore. This blog post aims to demystify the procedure, offering insights into its purpose, what to expect during a colonoscopy in Singapore, and resources to help you find a qualified gastroenterologist.

Why is Colonoscopy Important?

Colorectal cancer, affecting both the colon (large intestine) and rectum, ranks among the top cancers in Singapore. However, the good news is that it's highly preventable and treatable when detected early. This is where colonoscopy plays a vital role.

A colonoscopy is a visual examination of the inner lining of the colon and rectum using a long, flexible tube equipped with a light and camera. During the procedure, polyps, precancerous growths, can be identified and removed if necessary. Additionally, the doctor can examine for inflammation, bleeding, or other abnormalities.

Who Should Get a Colonoscopy?

The American Cancer Society recommends regular colonoscopy screenings for adults starting at age 45 for those with average risk. However, some individuals may require earlier screenings based on certain factors:

  • Family History: A family history of colorectal cancer significantly increases your risk.
  • Personal History of Inflammatory Bowel Disease (IBD): Ulcerative colitis or Crohn's disease can increase your risk of colon cancer.
  • Lifestyle Habits: Smoking and a diet high in red meat and processed foods are risk factors.

What to Expect During a Colonoscopy in Singapore

Preparation: The key to a successful colonoscopy is a clean colon. Your doctor will provide detailed instructions on dietary restrictions and a bowel preparation solution to clear your colon of waste.

The Procedure: Colonoscopy is typically performed on an outpatient basis. You'll likely receive medication to help you relax during the procedure. The doctor will insert the colonoscope through the rectum and gently guide it through the colon. If polyps are found, they can be removed with tiny instruments passed through the colonoscope.

Recovery: Following the procedure, you'll briefly remain in a recovery area until the medication wears off. You may experience some bloating or discomfort, which is typically short-lived.

Finding a Qualified Gastroenterologist for Colonoscopy in Singapore

Singapore boasts a well-developed healthcare system with numerous qualified gastroenterologists who specialize in colonoscopy procedures. Here are some resources to help you find the right fit:

  • Hospital Websites: Major hospitals in Singapore list their gastroenterology departments on their websites, often with details about the doctors' qualifications and areas of expertise.
  • Singapore Medical Council (SMC) Website: The SMC maintains a searchable online directory of all registered doctors in Singapore. You can filter your search by specialty (Gastroenterology) and location.
  • Professional Associations: The Singapore Gastroenterological Society website may list member gastroenterologists experienced in colonoscopy.
  • Word-of-Mouth Referrals: Ask your primary care physician or friends and family for recommendations.

Questions to Ask Your Gastroenterologist

Schedule a consultation with a shortlisted gastroenterologist to discuss your concerns and suitability for a colonoscopy. Here are some important questions to ask:

  • Am I a good candidate for colonoscopy?
  • What type of pre-colonoscopy preparation will I need?
  • What will happen during the procedure?
  • What are the risks and complications associated with colonoscopy?
  • Do you offer minimally invasive techniques for polyp removal?
  • What is the estimated cost of the procedure? Does my insurance cover it?


Colonoscopy is a valuable tool for early detection and prevention of colorectal cancer. By understanding the importance of this procedure, what to expect during a colonoscopy in Singapore, and available resources for finding a qualified gastroenterologist, you can proactively manage your colon health and reduce your risk of this serious health concern.
