Key takeaways:

 

  • A colonoscopy examines the large intestine (colon) and rectum for polyps, inflammation or cancer.
  • You’ll need to avoid solid foods the day before your exam. 
  • It’s performed while you’re sedated. 
  • After the procedure, you’ll need someone to drive you home. 

 

 

How to prepare for a colonoscopy

 

You’re probably not looking forward to having a colonoscopy. You may be concerned about prepping ahead of time. Or whether the procedure will be uncomfortable. But don’t worry. A little knowledge can make prepping and recovering much easier.

 

Here’s some info to help you avoid surprises and feel more comfortable during the procedure.

 

According to the American Cancer Society, colon cancer is the third most common cause of cancer deaths in the US.* A colonoscopy helps find colon and rectal polyps. It can also help find cancer.

 

Catching these early can improve treatment outcomes. This test also helps you manage health worries if you have a family history of colon cancer.

The American Cancer Society recommends starting regular screenings at age 45.  If you don’t have any risk factors, you only need to repeat the test every ten years. 

 

If you have a family history of colon cancer or symptoms that concern you, talk to your doctor about earlier or more frequent screenings. Check your plan documents or our clinical policy bulletin for more details about your coverage.

The prep process clears the colon for imaging. You’ll need to avoid solid foods the day before. You’ll also take a laxative recommended or prescribed by your doctor in either liquid or pill form. Think of this as an internal cleanse. Your provider may advise you to take the day off from work as the prep can be tiring.

You’ll be on a liquid diet the day before the test. Talk to your doctor about what you can have that day, but it will likely be limited to:

 

  • Coffee/tea with no creamer
  • Clear broth
  • Popsicles with no cream (make sure they’re not red or purple)
  • Clear juices (apple, white cranberry)
  • Gelatin (make sure it’s not red or purple) 
     

Foods to avoid include:

 

  • Solid foods
  • Anything with red or purple dye
  • Alcohol
  • Dairy
  • Soup (other than clear broth)

The test is generally quick and painless. This is thanks to sedatives that keep you calm and sleepy. A doctor will look around your colon with a long and flexible tube with a camera. The entire process normally takes around 30 minutes.

Because you’re given a sedative, you’ll need someone to give you a ride home.  It’s normal to have some bloating or gas, but it shouldn’t last long. If your doctor removes any polyps for further tests, those results are usually available in a few days.

Have regular screenings up to age 75. After 75, ask your doctor if you should keep up regular tests. They’ll consider your general health and the results of past screenings.

 

A colonoscopy is a powerful tool in preventing colon cancer. It’s well worth the mild discomfort. With strong preventive benefits, it’s a proactive way to manage your health. Remember, the best screening is the one that gets done. Don't wait to take control of your health today.
