Gastric Bypass Surgery


Gastric Bypass Surgery gives you a simple first step in eating small, healthy portions.

Gastric bypass surgery is a procedure in which your surgeon creates a small pouch from your stomach and the rest of the stomach is bypassed. The small pouch is attached directly to the small intestine. The newly created pouch can only hold a small quantity of food. Your stomach will secrete less of the hormone ghrelin, which is an appetite stimulant.

  • You will not get as hungry and when you do eat, you will likely feel full after eating only a small amount of food
  • By consuming less food overall, you will eventually be able to lose weight

What to Expect After Gastric Bypass Surgery

For the first few days after your gastric bypass surgery, you will be on a liquid diet. Until about week six after surgery, you will only be eating a limited amount of soft foods. This allows your digestive system to heal. If you had a laparoscopic gastric bypass, you may be able to go home about five days after your surgery if you are healing well. If you had an open abdominal surgery, you will probably go home about a week after your procedure. You will need to rest and avoid heavy physical activity during this time. You may not be able to lift heavy items. This is because your abdominal muscles need to heal.

You may need to come into your doctor’s office to have your surgical site checked and the bandages changed. Regular follow up visits are an important part of your care and are important for monitoring your progress.

Nutrition Tips for Gastric Bypass Surgery Patients

As a part of your gastric bypass surgery, you may need to participate in pre-surgical nutritional counseling. The goal of this counseling is to modify your eating habits. You will learn about making healthy food choices and substituting unhealthy foods. For example, one healthy food substitution could be to substitute a dessert like ice cream for healthier options such as Greek yogurt.

You will also learn about how many calories you should eat and the amounts of carbohydrates, protein, and fats that your body needs for optimal nutrition. Your doctor will also provide you with guidance on vitamins and minerals. It is important to adhere to your nutritional plan so that you can avoid diseases that are caused by vitamin and mineral deficiencies.

Your counseling will likely continue after surgery to reinforce good eating habits. Your doctor may give you guidelines about how many calories to eat, and this will change as you lose weight. As your body loses weight, it needs fewer calories to maintain that weight. For example, a person who weighs 400 pounds may be able to eat 3,000 calories per day and stay at the same weight, while a person who weighs 200 pounds would need to eat about 1,900 calories daily for weight maintenance.

Your doctor will work with you and provide post-surgical instructions that are tailored to your health and your unique situation. It is very important to follow these instructions carefully in order to see the most progress and to stay healthy.
