While there is no set post-surgery diet recommended to patients, there are certain guidelines you can follow. Diarrhea is quite a common side effect, so it’s important that you stay hydrated. Drink a lot of water, broth, and drinks that will help replace the minerals, fluids, and vitamins lost through diarrhea. It is far less likely that you will experience diarrhea, bloating, and gas if you stick to low-fat foods. These include beans, oatmeal, whole grains, vegetables, fruits, and fat-free dairy products. You should also gradually introduce foods that are high in fiber, such as prunes, oat bran, chickpeas, beets, and okra.
Foods that are high in soluble fiber are also beneficial and include wheat germ, legumes, carrots, nuts, potatoes, and spinach.
