What should I wear to the procedure?

Wear comfortable, loose-fitting clothing on the day of the procedure. You will change into a hospital gown for the colonoscopy, but comfortable clothing is recommended after the procedure.

What happens if I cannot complete the bowel preparation?

If you have difficulty completing the bowel preparation or cannot finish the laxative solution, inform your colorectal surgeon. Inadequate bowel preparation can affect the quality of the examination and may necessitate rescheduling the procedure.

How effective is colonoscopy in preventing colorectal cancer?

Colonoscopy is highly effective in detecting and preventing colorectal cancer. By identifying and removing precancerous polyps, the procedure greatly reduces the risk of developing colorectal cancer. Regular screenings are important for early detection and prevention.

Can I drive myself home after the procedure?

No, due to the sedatives or anaesthesia used during the procedure, you have to arrange for someone to drive you home. The effects of the sedatives can impair your ability to drive or operate machinery safely.

How do I prepare for a colonoscopy if I have diabetes?

Patients with diabetes should discuss their condition with their colorectal surgeon before the procedure. Special instructions regarding medications, diet, and blood sugar monitoring may be provided to ensure a safe and effective preparation and procedure.

Is colonoscopy Medisave claimable in Singapore?

Yes, colonoscopy is Medisave claimable in Singapore when performed for diagnostic or therapeutic purposes. This includes colonoscopy for colorectal cancer screening, polyp removal, and investigation of symptoms such as rectal bleeding or a change in bowel habits. The amount claimable depends on the procedure performed and your Medisave account balance. Dr. Sulaiman's team can provide detailed guidance on Medisave claims and any out-of-pocket costs during your consultation.

How much does a colonoscopy cost in Singapore?

The cost of a colonoscopy in Singapore varies depending on whether it is performed in a private clinic, day surgery centre, or hospital, and whether any additional procedures such as polyp removal are performed during the same session. As a general guide, a diagnostic colonoscopy at a private specialist clinic in Singapore typically ranges from $1,500 to $3,000 or more, inclusive of anaesthesia and facility fees. Medisave can be used to offset a portion of the cost for eligible procedures.

How long does it take to recover after a colonoscopy?

Recovery after a colonoscopy is generally quick. Most patients feel well enough to return home within 1 to 2 hours after the procedure, once the effects of the sedation have worn off. Most patients can resume normal activities, including returning to work, the following day. If polyps were removed during the procedure, your doctor may advise you to avoid strenuous activity for a few days.

Is colonoscopy covered by Medisave in Singapore?

Yes, colonoscopy is a Medisave-claimable procedure under the Singapore Ministry of Health approved list. Patients can use their Medisave account to offset the cost, subject to withdrawal limits. Dr. Sulaiman's team can advise on the exact claimable amount at your pre-procedure consultation.

How long does a colonoscopy take?

Dr. Sulaiman Yusof specialises in minimally invasive (laparoscopic) colorectal cancer surgery, which results in faster recovery and less pain.

What is the survival rate for colorectal cancer in Singapore?

The survival rate for colorectal cancer depends on the stage at diagnosis. When detected at an early stage (Stage I or II), the 5-year survival rate can exceed 80 to 90%. Unfortunately, many cases are diagnosed at a later stage, which is why regular screening is so important. Dr. Sulaiman encourages all eligible individuals to undergo colonoscopy screening to detect colorectal cancer early.

Can colorectal cancer be prevented?

While not all cases can be prevented, the risk of colorectal cancer can be significantly reduced through regular colonoscopy screening (which allows polyps to be detected and removed before they become cancerous), a healthy diet rich in fibre and low in processed meats, regular physical activity, maintaining a healthy weight, and avoiding smoking and excessive alcohol consumption.

At what age should I start colorectal cancer screening in Singapore?

What is the difference between internal and external haemorrhoids?

Internal haemorrhoids develop inside the rectum and are usually painless, though they may cause bleeding.

Dr. Sulaiman Yusof can assess and classify your haemorrhoids to recommend the most appropriate treatment.

How are haemorrhoids treated in Singapore?

Mild haemorrhoids can be treated with dietary changes, increased fibre intake, and topical creams. More severe cases may require rubber band ligation, sclerotherapy, infrared coagulation, or surgery (haemorrhoidectomy or stapled haemorrhoidopexy). Dr. Sulaiman Yusof, a specialist colorectal surgeon in Singapore, offers the full range of haemorrhoid treatments tailored to each patient's condition.

Are haemorrhoids dangerous?

Haemorrhoids are generally not dangerous, but they can cause significant discomfort and affect quality of life. Persistent rectal bleeding should always be evaluated by a doctor to rule out more serious conditions such as colorectal cancer. If you experience rectal bleeding, pain, or a lump near the anus, consult a colorectal specialist promptly.

What are the early signs of haemorrhoids?

Early signs of haemorrhoids include bright red blood on toilet paper or in the toilet bowl after a bowel movement, mild itching or irritation around the anus, a feeling of incomplete emptying after passing stools, and occasional discomfort or swelling near the anus. If you notice any of these symptoms, it is advisable to consult a doctor for an accurate diagnosis.

Can haemorrhoids go away on their own?

Small, Grade 1 or Grade 2 haemorrhoids can sometimes resolve on their own with dietary changes, increased fluid intake, and improved bowel habits. However, larger or more advanced haemorrhoids (Grade 3 or 4) typically require medical treatment. Delaying treatment can lead to worsening symptoms, so it is best to seek a specialist's advice early.

When should I see a doctor for haemorrhoids?

You should see a doctor if you experience rectal bleeding (even if you suspect it is from haemorrhoids), persistent pain or discomfort that does not improve with home remedies, a prolapsed haemorrhoid that cannot be pushed back in, or symptoms that recur frequently. A colorectal specialist like Dr. Sulaiman Yusof can accurately diagnose your condition and recommend the most effective treatment.

Are haemorrhoid treatments painful?

Most non-surgical haemorrhoid treatments such as rubber band ligation, sclerotherapy, and infrared coagulation are minimally invasive and generally well-tolerated with minimal discomfort.

Dr. Sulaiman Yusof will discuss all options and help you choose the most appropriate treatment for your situation.

How can I prevent haemorrhoids from recurring?

To prevent haemorrhoids from recurring, maintain a high-fibre diet with plenty of fruits, vegetables, and whole grains; drink at least 8 glasses of water daily; avoid straining during bowel movements; do not delay going to the toilet when you feel the urge; exercise regularly to improve bowel function; and avoid prolonged sitting, especially on the toilet. These lifestyle changes can significantly reduce the risk of haemorrhoid recurrence.

Is it safe to treat haemorrhoids during pregnancy?

Haemorrhoids are common during pregnancy due to increased pressure on pelvic veins and hormonal changes.

Invasive procedures are usually deferred until after delivery unless symptoms are severe. Always consult your doctor before starting any treatment during pregnancy.

What is the cost of haemorrhoid treatment in Singapore?

It is best to consult the clinic directly for a personalised cost estimate and to understand your insurance or Medisave coverage.

Is haemorrhoid treatment Medisave claimable in Singapore?

Dr. Sulaiman's team can advise you on Medisave eligibility and out-of-pocket costs at your consultation.

How long is the recovery after haemorrhoid surgery?

Recovery after haemorrhoid surgery varies depending on the procedure. After a haemorrhoidectomy, most patients can return to light activities within 1 to 2 weeks, though full recovery may take 3 to 6 weeks. Stapled haemorrhoidopexy generally has a shorter recovery period of 1 to 2 weeks. Dr. Sulaiman will provide detailed post-operative care instructions to support your recovery.

What foods should I avoid if I have haemorrhoids?

If you have haemorrhoids, you should avoid foods that can cause constipation or straining, such as low-fibre foods (white bread, processed foods), spicy foods, alcohol, and caffeine. Instead, focus on a high-fibre diet with plenty of fruits, vegetables, and whole grains, and drink at least 8 glasses of water daily to soften stools and reduce straining.

What causes anal fissures?
