A Comprehensive Step-by-Step Guide to Colonoscopy Preparation

A colonoscopy is an essential diagnostic procedure that helps detect abnormalities or conditions affecting the colon and rectum. Whether you are undergoing a routine screening or testing for specific symptoms, preparing for your colonoscopy is key to ensuring a smooth and successful procedure.

Gain a comprehensive understanding of the preparation process for your colonoscopy in Singapore, allowing you to approach the procedure with confidence and clarity.

What Is A Colonoscopy Procedure

A colonoscopy involves the use of a flexible tube with a camera, known as a colonoscope, to examine the lining of the colon and rectum. This procedure identifies abnormalities such as polyps, tumours or areas of inflammation.

During the procedure, the colonoscope is carefully inserted into the rectum and guided through the entire length of the colon. The camera transmits real-time images to a monitor, allowing for detailed inspection of the area. In some cases, tissue samples (biopsies) may be taken or polyps may be removed for further analysis.

The procedure is performed under sedation or mild anaesthesia, ensuring that the patient remains comfortable throughout. Although the idea of a colonoscopy may seem daunting, it is a quick and routine procedure, commonly performed by skilled specialists in Singapore.

The Importance of Colonoscopy for Colon Health

Undergoing a colonoscopy is one of the most effective ways to detect colorectal cancer and other conditions affecting the colon and rectum. This procedure detects and addresses potential issues including:

Inflammatory Bowel Disease (IBD): Colonoscopy detects flare-ups or changes in the condition at an early stage.

Polyps: Regular screenings can identify polyps, which are often precursors to cancer, allowing for their removal before they develop into cancer.

Colorectal Cancer: Colonoscopy detects colorectal cancer in its early stages, particularly important in Singapore, where it is one of the most common cancers.

How to Prepare for a Colonoscopy

Proper preparation is crucial for a successful colonoscopy. Our surgeon, Dr Thng Yongxian, will provide specific instructions based on your medical history, the following steps are involved:

Step-by-Step Guide to Preparing for a Colonoscopy

1. Dietary Adjustments

  • Switch to a low-fiber diet before the procedure
  • Follow a clear liquid diet to ensure your colon is clean the day before the colonoscopy

2. Bowel Preparation

  • Our surgeon will prescribe a special laxative solution that you must drink in stages. This will help clear your colon of stool or debris for a clear view during the procedure

3. Medication Adjustments

  • Inform our surgeon about any medications you’re taking

4. Arranging Transportation

  • Arrange for someone to drive you home after the colonoscopy

What to Expect During Your Colonoscopy

Day of the Colonoscopy

Arrival and Preparation

Upon arrival at the clinic or hospital, you will check in and complete necessary paperwork. You will then be asked to change into a hospital gown. A nurse will place an intravenous (IV) line in your arm to administer sedation or anesthesia during the procedure.

During the Procedure

Once you’re sedated, a colonoscope (a flexible tube with a camera) will be gently inserted into the rectum. You may feel some mild pressure or bloating as the colonoscope moves through the colon, but most people experience little to no discomfort due to the sedation. The camera will transmit images to a monitor, enabling our surgeon to examine the lining of your colon. The entire procedure typically lasts between 20 to 30 minutes.

Immediate Recovery

Once the procedure is complete, you will be taken to a recovery area where you will rest until the effects of the sedation wear off. During this time, it’s common to feel a bit groggy or drowsy, so take the opportunity to relax.

Rest and Hydration

After the procedure, it is important to rest and drink fluids to rehydrate your body. This will help counteract mild dehydration caused by the bowel preparation. You might experience some bloating or mild cramping, but this should subside within a few hours.

 

You will need someone to drive you home, as you will still be recovering from the sedation. Depending on our doctor’s advice, you may resume normal activities the following day, but it is best to avoid strenuous activities for at least 24 hours.

Frequently Asked Questions About Colonoscopy in Singapore

Is colonoscopy in Singapore covered by insurance?

Many health insurance policies in Singapore cover colonoscopy as part of preventive care or diagnostic procedures, especially if you are at risk for colorectal cancer. It is best to check with your insurance provider beforehand to understand the coverage and out-of-pocket costs for colonoscopy in Singapore.

The frequency of colonoscopy depends on your age, health history and risk factors for colorectal cancer. For most individuals, it is recommended to begin screening at age 50 and continue every 10 years if there are no signs of issues. However, if you have a family history of colorectal cancer or other risk factors, our surgeon may recommend more frequent screenings.

Wear comfortable, loose-fitting clothing to your colonoscopy appointment. You will be asked to change into a hospital gown for the procedure, but it is best to wear easy-to-remove clothing for convenience.

Most patients experience minimal discomfort during the procedure due to sedation or anesthesia. Colonoscopy in Singapore is performed with mild sedation, so you will be relaxed and may not feel any pain. Some people may experience mild cramping afterward.

If you have chronic conditions, such as diabetes or heart problems, inform our surgeon before your colonoscopy. They may need to adjust your medication or offer special instructions to ensure your procedure is safe.
