After the procedure, your diet will be forever altered.  Patients are instructed not to drink liquids with meals to avoid stretching the pouch.  They must give up caffeine as it can be dehydrating and an irritant to the stomach, and they must also forgo carbonated beverages as it often causes discomfort.  A multivitamin and mineral supplement must be continued indefinitely to ensure that deficiencies don’t occur years after the procedure. You've also got to re-discover your feelings of hunger and satiety to better maintain weight loss.

Bariatric surgery will affect your diet considerably. It is important to seek psychological, medical and social evaluations prior to having the surgery to be sure that it is the right decision for you. Initially, it is recommended to eat a high protein, low fat, low sugar diet of portions ½ to ¾ cup at a time 4 to 6 times a day. The most frequent complications are bloating, nausea, and vomiting. A food record noting your tolerance for specific foods in particular amounts helps to develop a program to avoid these episodes.

Restricted portions and types of food may present to be a challenge for some people post-surgery and cause weight to be regained. Many people gradually introduce larger portions and a wide variety of food into a diet with successful weight loss with bariatric surgery. Remember it’s a lifelong commitment and everyone responds differently so you will need to follow up lifelong with your health care team.
