What to Expect, Common Myths, & Next Steps

WHAT TO EXPECT DURING A COLONOSCOPY:

BEFORE THE PROCEDURE:

  • You will receive instructions for bowel prep. Many preps now use smaller volumes and clearer instructions.

  • A clean colon allows your doctor to see polyps clearly and remove them safely.

  • Hydration is key—drink plenty of clear liquids the day before.

DURING THE PROCEDURE:

  • You are fully asleep with safe sedation (most commonly propofol).

  • The procedure usually lasts on average 30 minutes.

  • If polyps are found, they are removed immediately.

  • Your breathing, heart rate, and comfort are monitored throughout.

AFTER THE PROCEDURE:

  • You wake up quickly and comfortably.

  • You may feel mild bloating for a short time.

  • You return to normal activity the next day.

  • Your doctor will review results and next steps with you.


COMMON MYTHS (and the truth):

“I will feel everything”

You won’t. You’re asleep and comfortable.

“I don’t need screening if I feel fine”

Polyps rarely cause symptoms and cancer can be silent as well.

“Prep is horrible”

Modern preps are easier, with better taste and lower volume.

“I’m too young”

Colon cancer in young adults is rising rapidly.

“I don’t have a family history, so I’m safe”

Most colon cancers occur without any family history.

WHEN TO TALK TO A DOCTOR SOONER:

  • Rectal bleeding (even small amounts).

  • Unexplained iron-deficiency anemia.

  • Persistent change in bowel habits.

  • Unintentional weight loss.

  • Ongoing abdominal pain.

  • Strong family history of colon cancer or polyps.

YOUR NEXT STEP:

Screening saves lives. If you are 45 or older—or younger with risk factors—talk to your physician about the right screening plan for you. A few minutes of prevention can protect decades of your future health.

Remember: Colon cancer is preventable, treatable, and beatable when caught early.
