How Surgery for Colorectal Cancer Affects What You Can Eat

You may not be able to eat for the first few days. You may get some nutrients through an intravenous line, called an IV, that’s put into one of your veins. At first, you will begin a liquid diet. Later, you will be able to add soft foods and then normal foods. It may take your colon several months to adjust to the trauma of surgery. During that time, you will need to eat a low-fiber diet. Be sure you discuss your diet with your doctor. The doctor may refer you to a nutritionist to help you plan your meals.
