Your Diet and Eating Habits

You will need to adjust your diet because of the changes that were made to your stomach during surgery. It is very important to adhere to your surgeon's diet recommendations. Some common recommendations include:

  • Chew your food slowly and thoroughly, to reduce it to very small pieces. You may want to grind your meat before eating it.
  • Wait two to three minutes between bites.
  • Drink fluids at a time other than when you are eating, to avoid a premature feeling of fullness that may make you feel like vomiting.
  • Avoid eating foods high in sugar and fat, such as non-diet soda, juices, high-calorie nutritional supplements and milkshakes. Eating many of these foods can lead to dumping syndrome, a rapid emptying of the stomach into the small intestine that causes considerable discomfort.
  • On the other hand, you should prioritize foods that contain high amounts of proteins, such as fish, dairy products, meat, beans and legumes.

You should also try to eat plenty of fresh vegetables and fruits.

  • Daily vitamin and mineral supplements at higher than normally recommended doses are a must, because you will not receive adequate nutrition from the small amounts of food you eat. You may wish to use vitamins in liquid or chewable forms, because they cause less discomfort than swallowing large solid vitamin pills.
  • B-complex vitamins, iron and calcium require special attention if you have had a Roux-en-Y gastric bypass, because of the changes to your digestive system.
  • Vitamin B-12 is particularly difficult for your body to absorb after surgery, and you should look into taking it in forms other than a pill.

Insufficient intake of vitamin B-12 will cause you to become fatigued easily.

  • Likewise, you should take calcium (as the citrate) in large amounts, to avoid early osteoporosis, a disorder in which the bones become porous, brittle and easily fractured.
  • Be careful with alcohol. It is absorbed and metabolized much more rapidly after surgery. In addition to the risk of rapid and unexpected intoxication, alcohol consumption can cause ulcers in your stomach pouch or intestine.
  • Plan meal times, and avoid snacking. You should eat several small meals per day because of your stomach's smaller capacity.
