Colonoscopy is one of the most important tools for checking the health of the colon and rectum. It allows doctors to examine the bowel lining, detect polyps, take biopsies when needed, and, in many cases, remove suspicious growths during the same procedure. In Singapore, colorectal cancer screening is commonly recommended from age 50 for people without symptoms, while those with family history or worrying symptoms may need earlier assessment.
Choosing where to go can feel confusing because Singapore has many private specialists, endoscopy centres, and colorectal clinics. This guide looks at colonoscopy providers that may suit different patient needs, from dedicated colorectal surgeons to multi-doctor gastroenterology groups.
1. Dr Thng Yongxian
For patients comparing a colonoscopy specialist in Singapore, Dr Thng Yongxian is a strong first option to consider for screening, surveillance, and therapeutic colonoscopy. His colonoscopy service covers screening and surveillance, with image-enhanced techniques such as NBI, i-scan, and chromoendoscopy listed on his clinic page.
Dr Thng is a Senior Consultant hepatopancreatobiliary and general surgeon. His practice also describes therapeutic colonoscopy services for polypectomy, bleeding control, dilation, and foreign body retrieval. This makes the clinic relevant for patients who are not only seeking a routine screening scope but may also need closer assessment because of symptoms, previous polyps, inflammatory bowel disease surveillance, or other risk factors.
Another practical advantage is accessibility. His clinic locations include Mount Alvernia, Mount Elizabeth Orchard, Mount Elizabeth Novena, Parkway East, and Gleneagles Medical Centre. For patients comparing providers around different parts of Singapore, this range of locations can make scheduling more convenient.
2. The Surgeons
The Surgeons is another established option for colonoscopy in Singapore. Its colonoscopy page describes the procedure as a method used to detect abnormalities or growths in the colon and rectum. The clinic is led by Dr Chew Min Hoe, who is described as a general and colorectal surgeon with more than 25 years in the public sector and experience in colonoscopy for screening and diagnosis.
This provider may suit patients who prefer a colorectal-focused surgical clinic, especially if they want a doctor who can advise on both screening results and possible colorectal conditions. Its page also explains when a colonoscopy may be recommended, including screening, family history, abdominal discomfort, gastrointestinal bleeding, anaemia, changes in bowel habits, and unexplained weight loss.
3. GUTCARE
GUTCARE is a multi-specialist gastroenterology group with doctors across several major private medical centres in Singapore. Its services include colonoscopy, gastroscopy, polypectomy, emergency haemostasis, and advanced endoscopy services such as advanced polypectomy and image-enhanced endoscopy.
This type of group practice may be useful for patients who want access to a wider team of gastroenterologists rather than a single-doctor clinic. GUTCARE lists doctors across locations such as Mount Elizabeth Novena Specialist Centre, Parkway East Medical Centre, Mount Alvernia Hospital, Gleneagles Medical Centre, Farrer Park Medical Centre, and Mount Elizabeth Orchard Medical Centre.
4. Colorectal Practice
Colorectal Practice is a team-based colorectal clinic led by Dr Dennis Koh, Dr Sharon Koh, and Dr Pauleon Tan. The clinic lists colonoscopy among its specialised services, alongside piles treatment, colon cancer care, rectal cancer care, diverticular disease, inflammatory bowel disease, and minimally invasive colorectal surgery.
This provider may suit patients looking for a colorectal surgery group with multiple clinic locations. The practice lists branches at Orchard, Novena, Gleneagles, and Mount Alvernia. It also states that its doctors are colorectal surgeons accredited by the Ministry of Health, Singapore.
5. Ho Kok Sun Colorectal
Ho Kok Sun Colorectal is led by Dr Ho Kok Sun, a colorectal and general surgeon. The clinic’s colonoscopy website states that Dr Ho is Ministry of Health-accredited and has more than 20 years of experience in diagnosing and treating colorectal diseases.
The clinic highlights colonoscopy screening and early detection, especially because colorectal cancer may not show symptoms until later stages. It may be worth considering for patients who want a colorectal surgeon who focuses heavily on colon, rectal, and anal conditions.
6. United Gastro and Endoscopy Clinic
United Gastro and Endoscopy Clinic provides specialist care for digestive system conditions, including those affecting the oesophagus, stomach, intestines, liver, biliary tract, and pancreas. Its colonoscopy page explains that colonoscopy helps doctors detect and prevent certain diseases by identifying abnormalities that may need further treatment.
The clinic’s explanation is useful for first-time patients because it clearly describes what happens during the procedure, including insertion of a flexible colonoscope, live image viewing, biopsy, and polyp removal when needed. This makes it a practical option for patients who want clear preparation and procedure information before booking.
7. Alpha Digestive and Liver Centre
Alpha Digestive and Liver Centre offers colonoscopy as part of its gastroenterology services. Its colonoscopy page explains that the procedure is a day procedure that usually takes around 30 to 60 minutes, and that biopsies or polyp removal may be performed where needed.
The clinic may be suitable for patients who want a gastroenterologist-led service that also covers broader digestive and liver concerns. Its website lists services such as gastroscopy, endoscopic ultrasound, ERCP, endoscopic mucosal resection, deep enteroscopy, capsule endoscopy, and liver-related assessments.
8. Alpine Surgical Practice
Alpine Surgical Practice is led by Dr Aaron Poh, a general surgeon specialising in colorectal surgery. The clinic lists colonoscopy, colorectal cancer surgery, haemorrhoid removal, and other surgical services among its areas of care.
The practice is located at Mount Elizabeth Orchard, Parkway East, and Farrer Park. Its site also highlights screening packages and describes colonoscopy as a way to detect and remove polyps before they become cancerous. This may appeal to patients who want a colorectal surgery clinic with multiple private hospital locations.
9. AliveoMedical
AliveoMedical describes itself as a one-stop gastroenterology clinic offering colonoscopy for screening, diagnosis, and polyp removal. Its colonoscopy page states that the procedure is often used in Singapore to detect early-stage cancer and evaluate gastrointestinal concerns.
The clinic explains the difference between preventive and diagnostic reasons for colonoscopy. Preventive reasons include screening for polyps or colorectal cancer, usually for adults aged 50 and above. In contrast, diagnostic reasons include rectal bleeding, changes in bowel habits, iron deficiency anaemia, and chronic unexplained abdominal or rectal pain.
10. ACE Specialist Surgery & Endoscopy
ACE Specialist Surgery & Endoscopy performs gastroscopy and colonoscopy for a range of gastrointestinal symptoms. The clinic describes itself as a private specialist clinic in Singapore with expertise in minimally invasive and endoscopic procedures.
Its locations include Gleneagles Hospital and Mount Elizabeth Hospital, Orchard. This provider may suit patients looking for a private specialist surgery and endoscopy clinic that can assess both upper and lower gastrointestinal symptoms in the same care setting.
How to Choose a Colonoscopy Provider
A good colonoscopy provider should offer more than the procedure itself. Patients should look at the doctor’s area of specialty, experience with screening and therapeutic colonoscopy, hospital or endoscopy centre access, communication style, bowel preparation guidance, cost transparency, and follow-up process.
It is also worth asking practical questions before the appointment. Will the procedure be done under sedation? What bowel preparation is required? What happens if polyps are found? Are biopsy, histology, anaesthesia, and facility fees included in the estimate? Can Medisave or insurance be used? These details can make a big difference to the overall patient experience.
When to Speak to a Doctor
Colonoscopy may be recommended for routine screening, but it is also used to investigate symptoms. You should speak to a doctor if you have rectal bleeding, persistent changes in bowel habits, unexplained weight loss, iron deficiency anaemia, ongoing abdominal discomfort, or a family history of colorectal cancer. In Singapore, people without symptoms are generally advised to begin colorectal cancer screening from age 50, while those at higher risk may need earlier advice.
Final Advice
There is no single colonoscopy provider that fits every patient. Some people may prefer a colorectal surgeon, while others may choose a gastroenterologist or a multi-doctor digestive health group. The best choice depends on your symptoms, risk profile, preferred location, insurance coverage, and whether you may need therapeutic intervention such as polyp removal.
