Colon cancer is the second leading cause of cancer in the United States, making colonoscopies essential for screening. Prior to a colonoscopy, patients must follow dietary restrictions and bowel preparation instructions from their doctor. This involves avoiding high-fiber and dyed foods starting 3 days before, clear liquids and laxatives the day before, and having someone drive them home after the procedure. Following the preparation protocol helps clear the bowels for an effective colonoscopy.

procedure. Take time to review it as there
may be information that pertains specifically
to your situation due to your medical history.

fiber foods and artificially dyed foods and beverages. You will
also need to plan to have a family member or friend who can
pick you up from your procedure.

Two days before the
colonoscopy, you will need to
continue to comply with the
dietary restrictions. It is also
a good idea to plan to work
from home so you can relax in
preparation for the procedure.

• Do not eat solid foods
• Stay hydrated, only consuming
clear liquids
