A colonoscopy is a diagnostic procedure to examine your colon lining. An endoscope, which is a long, thin, and flexible tube with a small camera attached, will be inserted into your colon through the anus.
Who Should Go For a Colonoscopy?
You should go for a colonoscopy if:
- You show symptoms of colorectal cancer, such as:
- A positive result for your Faecal Occult Blood Test or Faecal Immunochemical Test
- Abdominal pain
- A change in bowel habits
- Sudden or unexplained weight loss
- Anal bleeding
- You have a family history of colorectal cancer or polyps
- You are 50 years old and above
How to Prepare for Your Colonoscopy
It is important to clear your colon of solid waste before your colonoscopy. You are required to take prescribed laxatives to induce bowel movement. If your colon is not cleared completely, remaining solid waste may obstruct your doctor from getting a clear view. In such cases, you will need to reschedule your colonscopy.
You may also need to take or avoid certain medications before your colonoscopy. Your doctor will give you further advice, depending on your situation.
What to Expect for Your Colonoscopy
The colonoscopy is usually performed as a day surgery procedure, which takes about 10-20 min. You will be given light sedation to ease any potential discomfort. You will be laid on the side, and your knees tucked into your body. During the procedure, the doctor will insert the endoscope into your colon through your anus. Additional procedures, such as biopsies and polyps removal, may be done if needed.
After your colonoscopy, you will be moved to our Day Surgery ward for observation until your sedative wears off. After that, we will serve you light refreshments, and your doctor will visit you to explain the results.
