Your surgeon will provide you with a nutritional plan after your surgery. This will likely consist of a liquid diet before slowly reintroducing small amounts of soft food. Staying hydrated during the healing period helps patients avoid constipation and kidney stones. Your daily supplemental regimen to follow for the rest of your life typically includes a multivitamin, Calcium, Vitamin D, Iron, and Vitamin B12. Your doctor will recommend the dosages that are right for you.


Making healthy lifestyle choices moving forward is vital to maintaining the best health and quality of life. A diet that is high in protein and low in carbohydrates, especially low in simple carbohydrates, is ideal. Avoid sugar and processed foods as much as possible. Once you are eating whole foods again, stick to lean protein, fruits, and vegetables to keep your fiber and vitamin intake sufficient.


Bariatric surgery patients especially need a good quality vitamin and mineral each day for the rest of their life. It is also important to take any supplements that are recommended for you in particular. Although the specific amounts of supplements can vary from person to person, bariatric surgeons and dietitians both firmly agree that taking supplements is necessary to prevent malnutrition following bariatric surgery.


It is essential for bariatric surgery patients to have their vitamin and mineral levels checked regularly after surgery. This may include a multidisciplinary team, consisting of a dietician, a primary care physician, a gastroenterologist, as well as nursing staff to make sure that complications due to malnutrition following surgery are limited. Together, teams of doctors along with consensus guidelines can help provide better nutritional care to patients who have undergone bariatric surgery.
