Diet Restrictions After Bariatric Surgery
Regardless of which bariatric procedure that a patient undergoes, they will be on a planned diet as part of the recovery process. One of the most important things to remember is to follow your diet plan designed by our nutritionist and the team at North Florida Regional Medical Center. The post-surgery diet consists of four “phases” of foods. Following the plan, phase by phase, facilitates the healing process and allows the body to acclimate to its new condition.
Phase1: Liquid Diet (Days 1-10)
Immediately after surgery, patients are put on a liquid diet which consists of mild sources of nutrients for the healing stomach. It has two stages: clear liquids and full liquids.
- Clear Liquids (Days 1-4 for Gastric Bypass; Days 1-2 for Adjustable Gastric Band)- The substance of the diet is clear to nearly clear liquids. The liquids cannot have any solid pieces in them; this includes small pieces of pulp in juice. Liquids are to be sugar free and non-carbonated. The patient will sip them slowly. The goal is to build up to consuming 48-64 ounces a day without drinking so quickly that the patient feels nauseas. This limit applies to both Gastric Bypass and Adjustable Lap Band procedures.
- Full Liquids (Days 4-10 for Gastric Bypass; Days 3-10 for Adjustable Gastric Band) – After the body can handle clear liquids without a problem, the patient should switch to “full liquids”. These liquids can have some solid pieces in them, but it is important to make them as fluid as possible. Supplement shakes and even well cooked cereals (oatmeal or grits) can be eaten. The limit is 64 ounces of liquid per day for Gastric Bypass procedures and 78 ounces a day for Adjustable Lap Band patients. Low fat, low sugar food sources that are high in protein are the ideal choices.
Phase 2: Pureed Foods (Weeks 2-5 for Gastric Bypass; Weeks 2-3 for Adjustable Lap Band)
Once the healing process is finishing up and the patient’s body is adjusting to its new stomach, some more traditional foods can be included in the diet. 64 ounces of water should be drunk a day for Gastric Bypass patients while Adjustable Lap Band Patients should consume 72 ounces per day Keep in mind that it should be consumed in between meals. Drinking with a meal will cause the stomach to be full faster and reduce the amount of food that can be eaten. All food must be naturally soft or pureed so that any large pieces are broken down. Patients must avoid food choices that are hard to digest. For Gastric Bypass patients weeks 2 and 3 will be entirely pureed foods, in weeks 4 and 5 the patient can start to have some foods that are soft. For patients who undergo an Adjustable Lap Band procedure, pureed foods are eaten for 5 days and the rest of the phase can consist of soft foods. Remember to eat slowly so as to not over do it. The following food groups (with suggestions) are the basis of the pureed food diet and are listed in order of importance.
- Protein (The most important part of your diet) – Protein is the anchor of the diet and should be eaten first before the patient is full. Soft food choices are important and it is recommended that meals be pureed in a food processor. We suggest:
- Baby Food
- Scrambled Eggs
- Low Fat Yogurt
- Hummus
- Broiled fish (weeks 4 and 5)
- Tofu
- Fruits- Even though fruits are generally soft they should be mashed. All skin must be removed.
- Ripe bananas
- Unsweetened Applesauce
- Sugar free jams/jellies
- Strawberries
- Vegetables- Vegetables provide necessary vitamins. As with fruits, remove all skin and do not choose fibrous vegetables like celery. Remember green vegetables are the best.
- Mashed Potatoes (Not sweet potatoes)
- Boiled Carrots
- Well Done Spinach
- Grains- Grains must mostly be in pureed form as well. Many hot cereals are good choices. Use low fat milk when they are prepared to add protein.
- Grits
- Oatmeal
- Cream of Wheat
- Whole wheat toast (weeks 4 and 5)
Phase 3: Soft Foods (Weeks 6-8 This additional time with soft foods is only for Gastric Bypass patients. Adjustable Lap Band recipients move on to their permanent diet at week 4 or as instructed by their physician. The food suggestions here can be consumed during the second stage of Phase 2 for those who undergo Adjustable Lap Band procedures.)
The third phase does not require that any food be pureed. The diet consists of the soft foods that were eaten along with pureed foods at the end of the previous stage. Remember that patients should not drink within 30 minutes of a meal. They should chew food thoroughly, at least 20 times before swallowing. No fibrous foods are allowed, only soft easily digestible choices. Try:
- Protein- Beef is not allowed nor are cuts of poultry unless they are pureed.
- Fish
- Soy Burgers
- Tofu
- Fruits- Fibrous fruits and skins are still not allowed.
- Mangoes
- Berries
- Vegetables- Vegetables are to be cooked well until they are soft. Avoid raw vegetables and fibrous choices like asparagus.
- Collard Greens
- Carrots
- Grains- Toasting bread is still necessary as it makes it easier to digest. Enjoying hot cereals is still a great idea but do not add nuts, raisins or anything else.
For Gastric Bypass patients there is a fourth stage that includes the hard foods that can be eaten for the remainder of the patient’s life. This is to be discussed at a different time. Above all, heed the warnings in each dietary stage. Cooking foods well and following the steps precisely will produce the best results for the body.
