Colonoscopy & screening

Colonoscopy in Singapore, a gentler, 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 it under light sedation, so most patients sleep through it and go home the same day.

What a colonoscopy is

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, so Dr Lee can see the lining directly rather than guess from symptoms. It both finds the cause of a problem and screens when there are no symptoms at all.

If a small growth, called a polyp, is found, it can usually be removed in the same sitting, before it ever becomes a problem. That is why a colonoscopy is one of the few tests that can both find and prevent bowel cancer at once.

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.

Colonoscopy or gastroscopy

Colonoscopy and gastroscopy, and why they are often done together.

Both procedures are forms of endoscopy, a camera examination of the digestive tract done under sedation. A colonoscopy examines the large bowel from below, and is the test for lower-tummy concerns such as blood in the stool, a change in bowel habits, or screening for bowel cancer. A gastroscopy examines the upper digestive tract, the food pipe and stomach, and is the test for upper symptoms such as reflux, indigestion, or difficulty swallowing.

Many patients have symptoms in both areas, or are simply due to check both. When that is the case, Dr Lee can often perform the colonoscopy and gastroscopy in one sitting, under a single sedation, so it is one preparation and one recovery rather than two.

When a colonoscopy is worth doing

When a colonoscopy is worth doing, and when it should not wait.

The reasons people put off a colonoscopy, embarrassment, fear of the result, fear of discomfort, are the very reasons to have one. Most answers are reassuring, and 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
About blood in your stool

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 to rule out your worst fear and treat whatever is actually causing the bleeding, so the responsible step is simply to get it looked at rather than wait and worry.

On the day

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
Colonoscopy in older patients

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.

Recovery

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.

Fees & MediSave

Clear colonoscopy costs, with MediSave and insurance guidance.

Your exact fee is explained clearly at consultation, before anything is scheduled.

What a colonoscopy typically costs.

These are MOH public fee benchmarks, a guide not a quotation, shown before MediSave and insurance.

  • Surgeon fee, colonoscopy$1,200 to $1,800
  • With polyp removal$1,700 to $2,400
  • Anaesthetist$550 to $800
  • Day-surgery hospital fee$800 to $1,300

Typical total, with 9% GST: about $2,800 to $4,250.

Colonoscopy is MediSave claimable and usually covered under Integrated Shield Plans, so most patients pay only a small co-payment. Your exact figure is confirmed at consultation. If you are researching endoscopy costs in Singapore, these colonoscopy figures are the relevant private benchmark; a gastroscopy done in the same sitting adds its own separate fee.

You can check these figures against the published MOH fee benchmark page.

Anaesthetist and facility fees are charged separately and vary by hospital. A colonoscopy is done as a day procedure.

Common questions

Colonoscopy in Singapore, answered plainly.

Is a colonoscopy painful?
It is done under light sedation, so most patients are comfortable and remember little to nothing of the procedure. The preparation the day before, the bowel cleanse, is the part most people find more demanding than the colonoscopy itself.
How long does a colonoscopy take?
The colonoscopy itself usually takes about twenty to thirty minutes. Once you add the check-in, the sedation and time in the recovery lounge afterwards, set aside about half a day. It is a day procedure, so almost everyone goes home the same day.
Does blood in my stool mean I have cancer?
Usually not. Most bleeding comes from something benign such as piles or a small tear. A colonoscopy is the clearest way to find the actual cause and, in most cases, to rule cancer out. Getting it checked early is the calm, responsible step.
How should I prepare for a colonoscopy?
You follow a clear-liquid diet and take a bowel-cleansing preparation the day before, so the bowel lining can be seen clearly. Dr Lee's team gives you simple written instructions, and you can reach them with any questions.
What happens if a polyp is found during the colonoscopy?
If a small growth called a polyp is found, Dr Lee can usually remove it during the same colonoscopy, so you do not need a second procedure. Removing polyps early can lower the chance of them turning into bowel cancer later. Anything removed is sent to the lab, and Dr Lee explains what it means and whether any follow-up is needed.
At what age should I get screened?
Screening usually starts from around age 45 to 50 for people at average risk, and earlier if you have a family history of bowel cancer or certain symptoms. Dr Lee will advise the right starting age and interval for you.
How often do I need a colonoscopy?
It depends on what is found. After a normal screening colonoscopy, the next one is often about ten years later for people at average risk. If polyps were found, or you have a family history or other risk factors, Dr Lee usually suggests a shorter interval and explains why. You always leave knowing when your next check is due.
Can I have a gastroscopy at the same time?
Often yes. If you also have upper-tummy symptoms such as reflux, indigestion or difficulty swallowing, a gastroscopy can usually be done in the same sitting as your colonoscopy, under the same sedation. That means one preparation, one visit and one recovery instead of two. Dr Lee will advise whether doing both makes sense for you.
How much does a colonoscopy cost in Singapore?
As a guide, the MOH surgeon-fee benchmark for a colonoscopy in Singapore is about 1,200 to 1,800 dollars, or 1,700 to 2,400 dollars if a polyp is removed, with the anaesthetist and day-surgery facility fees charged separately. A colonoscopy is MediSave claimable and usually covered under Integrated Shield Plans, so most patients pay only a small share themselves. Your exact figure is explained at consultation, before anything is scheduled.
Will MediSave or my insurance cover it?
A colonoscopy is usually MediSave claimable and covered under most Integrated Shield Plans, and the team helps you check before anything is scheduled.
How long is the recovery, and when can I go back to work?
Recovery from a colonoscopy is short. Because of the sedation, you will need someone to take you home and you should not drive that day. Most people feel back to normal by the next day and can return to work then, though some mild bloating from the air used during the procedure is normal and settles quickly.
I am arranging this for an elderly parent. Is that different?
Older patients benefit from careful assessment of the bowel preparation and sedation, and from a plan built around their wider health. Dr Lee led geriatric surgical care in the public sector and brings that same considered approach to colonoscopy in older adults.
