Why Avoid Fresh Fruits & Vegetables Before a Colonoscopy?

A colonoscopy is a medical procedure which examines the colon for signs of cancer. Proper preparation before a colonoscopy is important in order to receive accurate results.

Purpose of the Diet

• The large intestine includes the colon and the rectum. The goal of the special diet is to clear the entire large intestine of solid matter.

Fiber

• Fruits and vegetables are high in dietary fiber. According to the Harvard School of Public health, fiber is a kind of carbohydrate that our bodies can't digest. The insoluble fibers in fruits and vegetables absorb water, increasing the size of the stool.

Small Intestine

• The small intestine processes proteins and fats, absorbing amino acids, vitamins and minerals. The digestion process then continues as the food moves into the large intestine.

Large Intestine

• The large intestine processes the fiber from fruits and vegetables, producing nutrients. Food can spend six to 73 hours in the large intestine.

Colonoscopy

• During a colonoscopy, a small flexible tube with a camera inside is passed through the large intestine. If the intestine is not completely empty, the doctor will not be able to get a clear view of the intestinal lining).
