  • Center for Bariatric Surgery: A Program of Rhode Island and The Miriam Hospitals

  • The type of bariatric surgery procedure you choice to have will determine your immediate post operative diet plan. You will be given specific instructions and guidelines as you go through the program.

    Please keep in mind: This is just an example of what you will face post-surgery. Food and diet choices will be tailored to each patient's needs.

    In addition, you can drink calorie-free liquids (especially water) as often as you want. It is essential that you maintain an adequate fluid intake by drinking at 48-64 ounces of fluid each day.

    You should not drink and eat at the same time.

    Some patients that have the gastric bypass surgery may have dumping syndrome. The dumping syndrome is a condition of crampy abdominal pain, lightheadedness and diarrhea that occurs when a high concentration of foodstuff, particularly sugars, rapidly enters the small intestine.

    Avoid carbonated beverages.

    It is essential that you change your eating behaviors in order to maximize weight loss and reduce the chance that you will develop nutritional deficiencies such as anemia, loss of bone or muscle mass from an inadequate intake of calcium or protein. Protein rich foods (low fat dairy, legumes, poultry, meat, fish, egg, and soy) should come first at a meal. You will require a protein supplement for several months.

    Vitamin, mineral, and calcium supplementation is required for the rest of your life.
