Diverticulitis Gastric Bypass Diet

Diverticula are pouches that form in the digestive tract, typically in the wall of the colon. The existence of these pouches is referred to as diverticulosis. When food particles are trapped in the diverticula, it can cause infection or inflammation. This is referred to as diverticulitis, an extremely painful condition. If you experience repeated diverticulitis attacks or other related complications, your health care provider may advise the removal of the diseased section of the colon (partial colectomy). A diet plan is necessary after a partial colectomy to provide adequate nutrition during recovery.

Clear Liquid Diet

Immediately after surgery, it may be several days before you are allowed to consume anything. Once you are permitted by your doctor, begin by taking in small sips of water. Do not drink too much at one time to avoid nausea. Gradually begin increasing liquids to stay hydrated. Only very thin liquids will be tolerated at first. Choose clear liquids that have sufficient calories. Some good examples are clear fat free broth or soup, juices, plain gelatin, sports drinks, fruit ices, popsicles, strained lemonade, weak tea, strained vegetable broth and water.

Low Fiber Diet

After the first week or so, your doctor will add easy to digest low fiber foods to your clear liquid diet. Examples of these types of foods are plain crackers, white bread or rolls, plain pudding, plain milkshakes, lean beef or fish, skinless chicken or turkey, skim milk, frozen yogurt, potatoes, white rice, canned peeled fruits and vegetables and cream soups.

High Fiber Diet

At approximately the five-week mark, your health care provider will suggest a gradual transition to your regular post-op maintenance eating plan. Learn to eat frequent small meals and be sure to chew each bite thoroughly to avoid irritation, swelling or obstructions. You will be able to resume your pre-operative diet, but your doctor will most likely recommend a high fiber, low fat, lean protein eating plan. A good balance of fruits, vegetables and whole grains is necessary to ensure the intake of sufficient fiber, vitamins and minerals. Some examples of these types of food choices are lean beef, chicken or fish, oatmeal, bran cereals, whole grain breads, sweet potatoes, brown rice, green beans, peas, apples and bananas.

Foods to Avoid

Learn to read labels on everything. It is especially important to limit fat intake to avoid the consumption of empty calories. After a partial colectomy, some foods will not be tolerated well. Examples of such foods to avoid are those that are known to cause gas, such as beans, melons, broccoli, cauliflower, cabbage, milk and milk products.

Fluid Intake

Drink at least eight 8 oz. glasses of healthy fluids each day, preferably filtered water, especially while on a high fiber diet. By absorbing water to soften stool and add bulk to the colon, you will prevent the development of constipation.

Vitamin and Mineral Supplements

Colon surgery changes the way your body absorbs food. It is more difficult post-surgery to absorb certain nutrients, such as calcium, iron and B vitamins. This can lead to nutritional deficiencies. Your doctor may determine that supplements are necessary in addition to a nutritious diet to avoid the development of anemia, pernicious anemia and osteoporosis. Discuss combining an adult-strength multivitamin, as well as iron, B complex, D and calcium supplements with your physician on a daily basis.
