If you are age 45 or older, you should talk to your doctor about getting a colonoscopy. A colonoscopy is a medical procedure that involves the examination of the large intestine (colon) and rectum using a flexible, lighted tube called a colonoscope. This procedure is commonly used to screen for colon cancer and other abnormalities in the colon. It remains the gold standard for the detection of cancerous growths in the colon.
Here, we have everything you need to know about preparing for a colonoscopy, what goes on during a colonoscopy, and what happens after the procedure. Should you have any questions or concerns, feel free to ask your provider.
Before the Colonoscopy
A colonoscopy cannot be performed unless the individual has emptied their colon. Otherwise, the doctor cannot view the colon properly, and this can lead to polyps being missed.
- Preparation: Your doctor will give you instructions on how to prepare for the colonoscopy. This typically involves a low-fiber diet 3 days before the test, switching to a clear liquid diet 1-2 days before the procedure, and the use of laxatives or a colonoscopy prep to clean out your colon.
- Medications: Your doctor may also give you instructions on what medications to take or avoid before the procedure. Make sure to follow your gastroenterologist’s instructions fully to avoid certain complications.
- Sedation: You will be given a sedative to help you relax during the procedure. The most common type of sedation used for colonoscopies is called conscious sedation, also known as procedural sedation. This involves the use of medications that help the patient relax and feel drowsy, but still conscious and able to respond to instructions from the doctor. The medication is usually given through an IV line in the arm, and the dosage can be adjusted throughout the procedure, as needed.
During the Colonoscopy
Make sure to show up at the office or clinic at your instructed time, so your colonoscopy can begin on time.
- Positioning: You will lie on your side with your knees bent during the procedure.
- Insertion of the Colonoscope: The colonoscope is inserted into the rectum, through the anus, and gradually advanced through the colon. The colonoscope inflates the colon with air to give the doctor a better view.
- Examination of the Colon: Images will be transmitted in real-time to a video monitor throughout the procedure. The doctor will examine the colon and look for any abnormalities such as polyps, which are small growths on the lining of the colon. If polyps are found, they will be removed during the procedure.
- Biopsy: If any abnormal tissue is found, the doctor may take a small sample (biopsy) for further testing.
- A colonoscopy usually takes an hour to complete, or more depending on how many polyps had to be removed.
After the Colonoscopy
It is important that you have someone you trust with you during the day of your colonoscopy to take you safely home following the procedure.
- Recovery: After the procedure, you will be monitored for a short period to make sure that you are recovering well from the sedation.
- Diet: You will be instructed to follow a clear liquid diet for a short period after the procedure, and then gradually return to your normal diet.
- Follow-up: Your doctor will discuss the findings with you after you awaken. You will be given instructions on any further testing or treatment, as needed.
