Understanding Screening Colonoscopy: A Comprehensive Guide to Procedure, Risks, and Costs in Singapore

What is a Colonoscopy?

A colonoscopy is a medical procedure that facilitates the real-time inspection of the large intestine, encompassing both the colon and the rectum. During the procedure, a healthcare provider inserts a specialised instrument known as a colonoscope—a slender, tube-like apparatus equipped with a camera—into the patient's anus. This enables the provider to evaluate the internal health of the large intestine directly. Colonoscopies serve as a critical diagnostic tool for identifying a broad range of gastrointestinal issues and stand as the gold standard for both screening and interventions related to colon polyps and cancer.

Recommended Guidelines and Risk Factors for Colorectal Cancer Screening

An individual is considered to be at elevated risk for developing colorectal cancer if they have a family history of either cancer or polyps, or if they have been diagnosed with inflammatory bowel disease. However, even in the absence of these risk factors or symptoms, the latest United States Preventive Service Task Force recommends screening for colorectal cancer from age of 45. Although various alternative tests like the Fecal Immunochemical Test (FIT) and CT scans of the colon are available — for which our clinic can advise on subsidy eligibility for Singaporean residents — they are limited by sensitivities and risk of CT related radiation. Colonoscopy therefore remains the most precise method for evaluating colorectal health.

Our colonoscopies are performed by highly trained/skilled partners with multiple years of experience in colonoscopy, dedicated to ensuring a comfortable and medically accurate scope procedure to address your health concerns.

Is Colonoscopy Painful? Understanding Patient Experience and Sedation Options

A colonoscopy is generally a quick and mostly painless procedure for the majority of patients. Sedatives are commonly administered before the procedure to induce a relaxed, sleepy state, and pain levels are continuously monitored throughout. Most patients usually complain little to no discomfort during or after the procedure. If you have particular concerns about pain or discomfort, please feel free to talk to our doctors.

How to Schedule a Colonoscopy: Steps and Considerations

If you are considering a colonoscopy, we recommend first consulting with our family doctors. This initial consultation enables us to assess whether a colonoscopy is the most appropriate procedure for your specific health concerns—since not all abdominal issues originate from the colon. After this evaluation, we can refer you to the appropriate specialists to perform the colonoscopy.

The initial consultation can be conducted either via telemedicine or through an in-person visit at our clinics. Our friendly medical team will guide you through the subsequent steps and provide further details as needed.

Preparing for a Colonoscopy: What You Need to Know

Preparing for a colonoscopy involves a few key steps, though the procedure itself is generally straightforward and minimally invasive. Prior blood tests or X-rays are usually not needed for most patients. However, if you have notable medical risk factors such as bleeding disorders or heart failure, our doctors will assess your condition and may recommend additional testing or alternative diagnostic methods.

One of the most crucial components of preparation is bowel-cleansing. This entails consuming a specially formulated liquid designed to clear out the contents of your bowel, thereby enabling a more accurate examination of the intestinal lining. Our medical team will offer specific guidelines for this bowel preparation to ensure optimal results for your colonoscopy.

Frequency of Colonoscopies: Guidelines Based on Individual Risk and Previous Findings

The frequency with which you should undergo a colonoscopy depends largely on the results of your initial examination. For most individuals, the recommendation is to begin colonoscopy screenings in their late 40s to early 50s. If you have a strong family history, screening at an earlier age may sometimes be required. If the examination reveals abnormalities such as polyps or inflammatory growths, your healthcare provider may recommend a follow-up colonoscopy within a 1-5 year time frame. Conversely, if your colonoscopy yields normal results, a subsequent examination is generally advised every 5-10 years.

Cost of Colonoscopy in Singapore: Pricing, Subsidies, and MediSave Options

The financial outlay for a colonoscopy in Singapore varies considerably based on whether the procedure is carried out in a public hospital as a subsidised patient or in a private healthcare setting. Generally, costs can range from $2,000 to $5,000 SGD.

It's important to note that subsidies in public hospitals are often available only for symptomatic patients; "screening" colonoscopies usually do not qualify for subsidies.

At ATA, we aim to make healthcare affordable. Our current pricing for a colonoscopy stands at $2,398 SGD (price NETT and inclusive of GST), not including additional costs such as biopsies and medications, if required.

For further financial guidance, please consult our medical team, as we can also offer referrals to specialist panels based on your preferences.

Additionally, our colonoscopies are MediSave-claimable, subject to approval, up to a sum of $1,600.
