For many people, the thought of undergoing a colonoscopy can feel intimidating, especially if it’s their first time. However, you can confidently approach your colonoscopy procedure with the right information and support.
This guide will cover everything you need to know about preparing for a colonoscopy in Singapore and what to expect before, during, and after the procedure.
What is a colonoscopy?
A colonoscopy is a procedure performed by doctors to check the inner lining of your large intestine (colon and rectum). It is commonly used to detect changes or abnormalities such as inflamed tissue, polyps, or cancer.
A colonoscope with a camera on its end is inserted into the rectum during the procedure. This camera sends images to a monitor, allowing the doctor to see the colon’s interior.
Colonoscopy preparation – what to expect?
Adequate preparation is crucial for a successful colonoscopy. Your colon needs to be thoroughly cleaned so the doctor can see any potential issues. Here’s what you can expect from the procedure:
Before
- Consultation and instructions: Your doctor will provide detailed instructions on how to prepare. Instructions usually include dietary restrictions and the use of laxatives.
- Dietary restrictions: You may need to follow a special diet days before the procedure. This diet often begins with avoiding high-fibre foods and gradually moves to a clear-liquid diet the day before your colonoscopy. Clear liquids include water, broth, and clear juices without pulp.
- Bowel preparation: The night before your colonoscopy, you must take a laxative solution to cleanse your bowel. This step is critical to ensure your colon is free of any residue that could obscure the doctor’s view. You may need to stay near a bathroom as the laxatives will cause frequent and urgent bowel movements.
During
- Arrival and sedation: On the day of the procedure, you’ll check in at the clinic. You’ll be given a sedative to help you relax and minimise discomfort. The sedative may make you drowsy, so arranging transportation home beforehand is necessary.
- The procedure: Once you’re sedated, the doctor will insert the colonoscope into your rectum and through your colon. You may feel mild cramping or pressure, but the sedation is administered to minimise discomfort. The procedure usually takes about 30 minutes.
After
- Recovery: After the procedure, you’ll rest in a recovery area until the sedative wears off. This can take about an hour. You might feel bloated or pass gas as your body expels the air introduced during the colonoscopy.
- Post-procedure care: You’ll receive instructions on how to care for yourself at home. These include dietary recommendations and signs to watch for that might require medical attention, such as severe abdominal pain or bleeding.
When can I see my colonoscopy results?
The timeline for receiving colonoscopy results can vary. The doctor will often discuss the initial findings with you immediately after the procedure. If polyps or other abnormal tissues are removed, the samples will be delivered to a lab for biopsy.
Biopsy results typically take a few days to a week. Your doctor will arrange another appointment to discuss the biopsy results and any necessary next steps.
When should I consider getting a colonoscopy?
Colonoscopy is an essential screening tool for colorectal cancer and other conditions. Here are standard guidelines for when to consider getting one:
- Age: Individuals aged 50 and above are encouraged to do a colonoscopy. Those with higher risks, such as a family history of colorectal cancer, might need to start earlier.
- Symptoms: If you experience symptoms such as persistent changes in bowel habits, rectal bleeding, unexplained weight loss, or abdominal pain, your doctor might recommend a colonoscopy to determine the cause.
- Follow-up screenings: If you’ve had previous polyps or colorectal cancer, regular follow-up colonoscopies may be necessary to monitor for recurrence or new growth.
