5 common questions about colonoscopy

Going for a colonoscopy is probably not at the top of your list, right? If you are over the age of 40, however, it really should be.

This quick Q&A from Dr du Plessis will tell you why:

• Who needs a colonoscopy? 

It is recommended that anyone over the age of 40 has a screening colonoscopy to assess their gastrointestinal health. If you have a family history of colon cancer, more frequent testing should be done, and from a younger age.

•  What is a colonoscopy for? 

A colonoscopy is the best method for early detection and diagnosis of various gastrointestinal conditions, including colorectal cancer. It is a good method to investigate the cause of abdominal pain, blood in the stool, diarrhoea, or a change in bowel habit.Pre-cancerous polyps or other gastrointestinal anomalies can be picked up and treated during a colonoscopy, which is preferable to waiting until symptoms appear.

• Do you need to be admitted to hospital for a colonoscopy? 

The modern colonoscopy is now commonly performed in the rooms of specialists and hospital admittance is not necessary. Doing the procedure in doctor’s rooms makes the experience for private, personal and relaxed. You will also have the opportunity to have a conversation with your doctor and look at the photos.  

• How does the procedure work?  

Before: There is a perception that you must drink a huge amount of intolerable liquid in the 24-hour period before a colonoscopy, but the preparations have changed significantly over the years. Nowadays, you only drink about three glasses of preparation and two to three litres of water in between. The preparation itself has also been improved and doesn’t cause nausea or vomiting any more. 

During/after: Everything is more sophisticated now, a specialist anaesthetist is on hand to ensure the sedation happens effectively without discomfort, and the surgeon focuses on the colonoscopy. You will be under sedation for no longer than 45 minutes and then be awake and able to converse within five to ten minutes. Like with any sedation, though, you should not drive until 12 hours after the procedure, as your reaction time may be affected. That usually takes you to the following morning

• Will medical aid cover the procedure? 

Generally, medical aids process a colonoscopy under the in-hospital benefit, even if it is done in the doctor’s rooms. There is often a co-payment for your bill, but having the procedure done in the doctor’s rooms is usually the most cost-effective option.
