Why a colonoscopy?

- Screen for colon cancer
What’s a colonoscopy?
A colonoscopy is a visual examination of the digestive system using a narrow flexible tube called a colonoscope. It’s an important exam to diagnose and treat bowel conditions.
To obtain a good image of the bowel lining, the bowels must be empty. That’s why doctors ask to prepare by following a strict low residue diet before the exam.
Vegan colonoscopy prep
The vegan colonoscopy prep is two steps:
- Low-residue diet – 2 to 6 days before the exam. The timeframe depends on the gastroenterology center you booked your exam. Follow the timeframe provided by your gastroenterologist. The low residue diet, also known as a low fiber diet, is a diet designed to reduce the amount of stool in your large intestine. It’s a temporary diet that helps ‘rest’ your bowels and prepares for colon exams.
- Liquid diet – on the day of the examination. The liquid diet consists of cleansing the bowel drinking a preparation called Glycoprep. During a liquid diet, you will only drink clear fluid, no solid food.
Low-residue diet – 2 days to 1 week before
Depending on the gastroenterology center where you perform the exam, y0u will be asked to follow a low-residue vegan diet for 2 to 6 days before the colonoscopy.
