What to Expect During Your Colonoscopy?

Colonoscopy is not just a vital diagnostic tool; it’s also an important preventative measure. By checking the entire colon and rectum for abnormal growths such as polyps, this procedure can help diagnose colorectal cancer early. Early detection can help improve your chances of successful treatment and potentially save lives.

Why is Colonoscopy Important?

Colonoscopies can identify and remove polyps before they become cancerous, giving you a huge advantage in the early detection of colorectal cancer.

This is recommended for those above the age of 45, those who are not up-to-date with colorectal cancer screening tests, or those who may have other risk factors for developing colon cancer.

In addition to helping detect and prevent the early stages of colorectal cancer, colonoscopies can also diagnose other gastrointestinal issues such as appendicitis, inflammatory bowel disease, and many others.

Colonoscopy Preparation: What Should You Do?

Before undergoing a colonoscopy, you or your loved one must follow several essential steps. This involves informing the medical team about your health and certain aspects of your life before, during, and after the procedure. 

​Before the Procedure

It is important to discuss any health concerns with your doctor and let them know if you have any allergies, especially to sedatives. Alternatively, you may go through a virtual colonoscopy instead.

Your doctor may require you to follow a specific bowel preparation food plan, which may involve restricting solid foods or only consuming a low-fibre diet and clear liquids prior to the procedure.

You will also be prescribed a laxative to keep your bowel empty during the colonoscopy. Applying vaseline around the anus before taking laxatives can help to reduce the irritation caused by frequent bowel movements. 

It is also important to shower and avoid using perfumes, lotions, or deodorants before your appointment.

During the Procedure

A large flexible tube, about a quarter of an inch in diameter, is inserted into the large intestine and used to inspect the inner lining of your rectum and colon.

The colonoscope transmits images to a monitor, allowing the doctor to examine for any colon polyps or a tissue sample that can be tested for rectal cancer or other gastrointestinal issues.

A large flexible tube, about a quarter of an inch in diameter, is inserted into the large intestine and used to inspect the inner lining of your rectum and colon.

The procedure lasts around 20 to 30 minutes, and you will be either awake or asleep (under general anaesthesia or pain medication), depending on what was discussed with your doctor beforehand.

What Should You Expect?

Most people report feeling no or only slight discomfort during the procedure after the colonoscope is removed. 

If any polyps are detected and removed, they will be sent to a lab for further testing. The results of this test should be available within a few days.

After the procedure, it is important to take it easy for the rest of the day and drink plenty of fluids to help stay hydrated.

Your doctor will provide you with specific instructions on what to do after the procedure, such as when it is safe for you to resume your normal diet, activities, or drive.

Virtual Colonoscopy

Virtual colonoscopy, or CT colonography, is another type of colon diagnostic test that uses computed tomography (CT) scans to create cross-sectional images. 

It is a minimally invasive procedure and can detect abnormalities such as polyps and tumours in the colon.

However, a virtual colonoscopy can't remove any detected abnormalities and therefore should not be used as a replacement for the real procedure. 

Virtual colonoscopy is only recommended for those who cannot undergo a regular colonoscopy due to medical conditions or bodily restrictions.

Who Should Get a Colonoscopy?

Colonoscopies are essential in detecting colorectal cancer early and helping to prevent it. The American Cancer Society recommends that people aged 45 or older should get a colon cancer screening test every 10 years.

Those with a family history of developing colorectal cancer or who have other risk factors for the disease may need to start screening earlier or get tested more frequently. 

It is essential to discuss your individual risk factors and needs with your doctor to determine the optimal timing for undergoing a colonoscopy.

Are There Any Side Effects of Colonoscopy?

The side effects and risks of colonoscopy are minimal. However, it is important to talk to your doctor if you experience any symptoms like:

• Bleeding or blood clots

• Difficulty passing gas

• Abdominal pain

• Fever or chills

• Bloating

These could be signs of a complication that needs further medical attention.
