Vegan Colonoscopy Prep

Updated: Oct 15


Anatomy: Large Intestine

In the United States, colon cancer is ranked as the third most prevalent type of cancer, with an estimated 52,550 deaths in 2023. According to the Centers for Disease Control and Prevention (CDC), to monitor for swelling, tissue irritation, polyps, and cancer within the large intestine (colon) and rectum, individuals between the ages of 45 to 75 are encouraged to speak with their healthcare provider and be screened for colorectal cancer every 10 years. For those that are between the ages of 76 to 85, an individual approach may be taken.



What is a colonoscopy? How is a colonoscopy done?

The primary method of colorectal cancer screening is a colonoscopy. For this screening, a physician will use a flexible handheld device equipped with a camera mounted at its tip called a colonoscope to look for changes through the rectum. If an abnormality or polyp is observed by the doctor, a tissue sample may be taken for lab testing. Some alternative options to colonoscopies are stool tests, flexible sigmoidoscopies, and CT colonography.


Colonoscopy Prep Medications

Before the procedure, bowel preparation via medication will be needed for clean results. Bowel preparation medications typically come in a container with powder to mix with water or clear flavored liquids, with detailed directions for use and with an approximate onset of action of 1 to 3 hours. Depending on the appointment time, each kit is typically started the day before the exam and completed that same day or the day of the exam with at least 3 hours of no liquids and food before the procedure. An alternative option to bowel prep solutions is Sutab, for patients who prefer to take tablets. Each box of Sutab has directions for use, 2 bottles of 12 tablets, and a cup with a water fill line. Once the colon and rectum are cleared, bowel movements should be a clear yellow liquid.
