Demystifying Colonoscopy

Colonoscopy can seem like a scary procedure, but it’s important to understand how this procedure can help you on your health journey. Together, let’s debunk how colonoscopies work, what you should expect, and who should be getting them. 

What is a Colonoscopy?

A colonoscopy is a type of exam used to look for changes in your large intestine and rectum. It is used to detect swollen, irritated tissues, polyps, or signs of cancer in the colon.

Your doctor will insert a long, flexible tube into the rectum, called a colonscope. There is a tiny video camera at the tip of the tube, allowing your doctor to view the inside of your colon. During your colonoscopy, it is possible to remove polyps or other types of abnormal tissue through the scope. 

When Should I Get a Colonoscopy?

Your doctor may order a colonoscopy if you have experienced the following symptoms:

• An unusual change in your bowel habits, including diarrhoea or constipation.
• Presence of blood in your stools.
• Persistent abdominal discomfort such as cramps, gas, or pain.

For individuals over the age of 50 years old with no family history or symptoms of colorectal cancer, it is recommended to get a colonoscopy. Similarly, if your family has a history of colorectal cancer, you are also encouraged to go for regular colonoscopies as part of colorectal cancer screenings.

These symptoms are often signs of conditions such as colorectal cancer, which is often only detected in the later stages. A colonoscopy can help with early detection, leading to a better prognosis.

What Should I Expect During a Colonoscopy? 

Before your procedure

You need to empty out your colon before your colonoscopy in order to get a good view of your colon and rectum during the exam. This can be done through:

• Following a special diet the day before the exam, as advised by your doctor.
• Taking a laxative the night before your procedure.

During the procedure

Usually, you will be sedated or given pain medication to avoid any feelings of discomfort during your colonoscopy.

Your doctor will insert the colonoscope into your rectum. This device contains a light and a tube that allows the doctor to pump air, carbon dioxide, or water into your colon. This will inflate your colon, providing a better view of the internal lining. Your doctor may also use the colonoscope to take tissue samples, or remove polyps and other forms of abnormal tissue.

This procedure may take around 30 to 60 minutes.

After the procedure

You may feel bloated or gassy for a few hours after the colonoscopy as you clear the air from your colon. You may also notice a small amount of blood with your first bowel movement after the exam, which should not be a cause for concern.

What Happens After a Colonoscopy?

Following your colonoscopy, your doctor will go through the results and advise you on the next steps you should take.

If no abnormalities are found, your colonoscopy is considered negative. It is generally recommended to repeat this procedure at intervals of 5 to 10 years time if you are at average risk of colorectal cancer. 

If polyps or abnormal tissue is found, your colonoscopy is considered positive. Most polyps are not cancerous, but some may have to be sent for analysis to determine if they are cancerous, precancerous, or noncancerous. Your doctor may recommend another colonoscopy sooner in order to monitor your condition.

A Colonoscopy Can Save Your Life

Colorectal cancer is the third most common cancer in the world for men and the second most common cancer for women. Through early detection through colonoscopy, you will be able to treat your condition more effectively and increase your chances of a better prognosis.
