Common Signs You Shouldn’t Ignore
Many people delay seeing a colorectal specialist because the symptoms are uncomfortable to talk about. But it's advisable to see a specialist when symptoms reach the following:
Rectal bleeding or blood in your stool
Persistent changes in bowel habits (diarrhoea, constipation, or both)
Ongoing abdominal bloating or cramping
Unexplained weight loss
A feeling that your bowel isn’t emptying completely
Lumps or pain around the anal area
Dr Poh explains, “I think a lot of patients actually come wanting just some form of reassurance or even if possible, an answer which oftentimes will reassure them as to what they have going on with them."
Colonoscopy Explained: A Simple Step That Can Save Lives
When a patient experiences symptoms like rectal bleeding, unexplained weight loss, or a change in bowel habits, one of the most effective ways to investigate the cause is through a colonoscopy. Though the idea of a scope exam may feel intimidating, this procedure plays a key role in both diagnosis and prevention.
Colonoscopy allows direct visual examination of the colon using a flexible camera. It helps detect inflammation, polyps, bleeding, or even early signs of cancer and allows for polyp removal during the same procedure if needed.
For patients, this means two key benefits: early detection of potential problems and the opportunity to remove polyps before they develop into something more serious, all in one session.
Services at Alpine Surgical Practice
People visit a colorectal and general surgeon in Singapore for many reasons. Some patients come in with ongoing abdominal discomfort or changes in bowel habits, while others seek care for haemorrhoids, hernias, or rectal bleeding. These concerns may feel sensitive to discuss, but they can significantly affect comfort, routines, and long-term health.
At Alpine Surgical Practice, care ranges from day-to-day digestive concerns to more complex surgical needs, with a focus on personalised, evidence-based treatment.
Conditions commonly treated include:
Colorectal polyps and cancer
Haemorrhoids (piles)
Anal fissures and fistulas

Appendicitis and abdominal infections
Gallbladder stones
Rectal bleeding or change in bowel habits
Procedures and treatments available include:
Colonoscopy and gastroscopy
Minimally invasive (laparoscopic) surgery

By offering both diagnostic procedures and advanced surgical options under one practice, patients receive care that is timely, focused, and adapted to their needs at every stage.
What to Expect During Your First Visit
Many patients decide to see a colorectal surgeon after experiencing symptoms like rectal bleeding, abdominal discomfort, or changes in bowel habits. Some are referred for further evaluation after a screening test, while others simply want peace of mind.
Before the Appointment
If you’ve had previous scans, lab results, or a referral letter, bring them along. It’s also helpful to note when your symptoms started, any changes over time, and your family history of colorectal conditions or cancer.
During the Consultation
You can expect a detailed discussion of your symptoms, medical history, and lifestyle. Depending on your condition, Dr Poh may perform a physical examination and discuss whether further tests (such as a colonoscopy or imaging) are recommended.
Dr Poh explains also elaborated on how they can also provide additional treatment options for the patient to mull over if they're having trouble deciding.
This approach ensures each patient receives care that is respectful, informative, and tailored to their needs.

Frequently Asked Questions (FAQs)
1. When should I see a colorectal surgeon?
Consider seeing a colorectal surgeon if you notice persistent rectal bleeding, ongoing changes in bowel habits, abdominal discomfort, or a lump near the anal area. These may indicate issues like haemorrhoids, polyps, or other conditions that benefit from early assessment.
2. Is rectal bleeding always serious?
Not always, but it’s worth checking. Common causes include haemorrhoids or anal fissures, but bleeding can also be an early sign of colorectal polyps or cancer. A medical review helps rule out more serious problems.
3. Does a colonoscopy hurt?
Colonoscopy is usually done under sedation, so most patients feel little to no discomfort during the procedure. It’s a safe and accurate way to detect polyps, bleeding, or other abnormalities in the colon.
4. Are haemorrhoids always treated with surgery?
No. Many cases can be managed with medication, diet changes, or outpatient procedures. Surgery is typically reserved for more severe or recurring haemorrhoids.
5. What’s the difference between a colorectal surgeon and a gastroenterologist?
Both treat digestive issues, but colorectal surgeons focus more on surgical and procedural management, including colonoscopy, polyp removal, and surgery for haemorrhoids, hernias, and colorectal cancer.
