How will a gastric bypass procedure change my eating habits?

Rebecca Beecroft

Gastric bypass will limit the amount of food you can eat at one time because the smaller stomach pouch will make you feel full sooner.

Depending on how the procedure is done, you will have to give up all carbonated beverages for at least one year.

You will need to eat a very balanced diet because you need to focus on meeting your body's metabolic needs, which means eating lean protein and lots of fruit and vegetables. You also need to maintain calorie restrictions, usually not more than 1,200 calories a day.

High fat meals may cause dumping syndrome, which is a heavy feeling in the stomach, cold sweat, and then uncontrolled diarrhea. This will be important to remember when dining out.

Gastric bypass surgery works by decreasing the absorption of food in the gastrointestinal system and altering metabolism. After surgery, you will be able to go back to your favorite restaurant and order your favorite meal, but you will not be able to finish the entire serving. Depending on the individual patient, we typically expect anywhere from 50 to 150 pounds or more of weight loss.
