Colonoscopy in Singapore, a calmer, clearer way to check.
If you have noticed blood in your stool, a change in your bowel habits, or you are simply due for screening, a colonoscopy is the clearest way to find out what is really going on. Dr Daniel Lee performs colonoscopy under light sedation, so most patients sleep through it and go home the same day. These problems are more common than you think, there is nothing to be embarrassed about, and the goal is a calm answer, not a frightening one.
A gentle, guided look at the lining of your large bowel.
A colonoscopy uses a thin, flexible camera to examine the full length of your large bowel, or colon. It lets Dr Lee see the bowel lining directly, which is far more reliable than guessing from symptoms alone. It is both a way to find the cause of a problem and a way to screen when there are no symptoms at all.
If a small growth, called a polyp, is found, it can usually be removed during the same colonoscopy, before it ever has the chance to become a problem. That is why a colonoscopy is one of the few tests that can both find and prevent bowel cancer in a single sitting.
Diagnostic colonoscopy
When you have symptoms such as bleeding, a change in bowel habits, or ongoing discomfort, this finds the cause so the right treatment can follow.
Screening colonoscopy
When you have no symptoms but are due for screening, often from around age 45 to 50, or earlier with a family history of bowel cancer.
Polyp removal
If a polyp is found, it is usually removed during the same procedure, which lowers your future risk before anything has time to develop.
Surveillance colonoscopy
A planned follow-up look for patients who have had polyps or cancer before, at the interval Dr Lee sets out for your situation.
When a colonoscopy is worth doing, and when it should not wait.
Many of the reasons people put off a colonoscopy, embarrassment, fear of the result, fear of discomfort, are the very reasons to have one. A colonoscopy gives you a clear answer, and most answers are reassuring. The ones that are not are far easier to deal with early.
- Blood on the toilet paper, or blood in your stool
- A lasting change in bowel habits, looser or harder than usual
- Ongoing abdominal pain, bloating or a feeling you cannot fully empty
- Unexplained weight loss, tiredness, or low iron
- You are due for screening, or have a family history of bowel cancer
Bleeding does not mean cancer, but it should always be checked.
Most bleeding from the back passage comes from something benign, such as piles or a small tear, not cancer. The point of a colonoscopy is not to confirm your worst fear, it is to rule it out, and to treat whatever is actually causing the bleeding. The responsible, and usually reassuring, step is simply to get it looked at rather than wait and worry.
Sedated, straightforward, and home the same day.
After a clear-liquid diet and a bowel-cleansing preparation the day before, the colonoscopy itself usually takes around twenty to thirty minutes. It is done under light sedation, so most patients are comfortable and remember little to nothing of it.
You rest in the recovery lounge until the sedation wears off, and Dr Lee explains what was found before you leave. Because it is a day procedure, almost everyone goes home the same day, with clear instructions and a number to reach the team.
- Light sedation, so you are comfortable throughout
- Around twenty to thirty minutes for the procedure itself
- Polyps removed during the same colonoscopy where suitable
- Day procedure, home the same day for almost everyone
A surgeon who built care around older patients.
For an elderly parent, the questions are different. Is the bowel preparation safe? Is the sedation safe? As the former Surgical Lead for Geriatric Surgery at Khoo Teck Puat Hospital, Dr Lee developed assessment and recovery pathways designed around older patients, and co-authored a 2024 review in the Journal of Gastrointestinal Surgery on how surgeon-led geriatric care drives good outcomes in older patients undergoing colorectal cancer surgery.
For families weighing up a colonoscopy or surgery for a parent, that experience is the difference between a procedure and a recovery. More about Dr Lee's background and approach.
A short recovery, with clear next steps.
Home the same day
Once the sedation has worn off, almost everyone goes home the same day. Because of the sedation, you will need someone to take you home and should not drive that day.
Back to normal the next day
Most people feel back to themselves by the following day. Some mild bloating from the air used during the procedure is normal and settles quickly.
Clear results and a plan
Dr Lee explains what was found before you leave, and any tissue or polyp removed is sent for testing. You will know what the results mean and what, if anything, happens next.
Clear colonoscopy costs, with MediSave and insurance guidance.
Fees depend on whether the colonoscopy is diagnostic or for screening, whether a polyp is removed, and the hospital. As a public guide, the Ministry of Health publishes surgeon-fee benchmarks. The figures below are the MOH surgeon-fee benchmark with GST. The anaesthetist (sedation) fee and the hospital or day-surgery facility fee are charged separately and vary by hospital. Your exact fee is explained clearly at consultation, before anything is scheduled.
| Type of colonoscopy | MOH surgeon fee benchmark (with GST) |
|---|---|
| Diagnostic or screening colonoscopySF702C / SF703C | SGD 1,308 to 1,962 |
| Colonoscopy with polyp removalSF704C | SGD 1,853 to 2,616 |
| Gastroscopy, if done at the same timeSF701I | SGD 709 to 1,199 |
These are published fee benchmarks, before MediSave and insurance. A colonoscopy is typically MediSave claimable, and screening colonoscopy and day-surgery procedures are usually covered under Integrated Shield Plans, so most insured patients pay much less out of pocket. The team works out your likely cost with you before anything is scheduled.
Surgeon fee benchmark only. The anaesthetist (sedation) fee (about SGD 600 to 870 with GST) and the hospital or day-surgery facility fee are charged separately and vary by hospital. A colonoscopy is done as a day procedure.
