Pre & Post Gastric Bypass Q & A

What is a gastric bypass?

A gastric bypass is bariatric surgical procedure that helps people who are seriously obese lose weight.

There are several types of gastric bypass, all of which involve reducing your stomach's capacity by either removing part of the stomach or blocking it off. In some cases, bypass surgery takes away the part of your stomach that produces appetite-stimulating cells as well.

A full gastric bypass (known as a Roux-en-Y gastric bypass) involves cutting and reconnecting the small intestine. This further aids weight loss by limiting the extraction of nutrients.


The pre-surgery diet is geared toward reducing the amount of fat in and around your liver. This reduces the risk of complications during the surgery.

After the surgery, your doctor will tailor the general diet guidelines for you. The post-surgery diet usually consists of several weekly phases. It helps you recover, meet the needs of your now smaller stomach, and gain healthier eating habits.

Diet before your surgery

Losing weight before surgery helps reduce the amount of fat in and around your liver and abdomen. This may allow you to have a laparoscopy rather than open surgery.

Laparoscopic surgery is less invasive, requires much less recovery time, and is easier on your body.

Losing weight prior to surgery not only keeps you safer during the procedure, but it also helps train you for a new way of eating.

Your exact eating plan and pre-op weight loss goal will be determined by your healthcare provider and likely with the help of a registered dietitian.

Your eating plan may begin as soon as you’re cleared for the procedure. If sufficient weight loss doesn’t occur, the procedure may be postponed or canceled. For this reason, you should start the diet plan as soon as you can.


Guidelines will vary from person to person, but they may include the following: 

  • Eliminate or reduce your intake of saturated fats, including whole milk products, fatty meat, and fried foods.
  • Eliminate or reduce your intake of foods that are high in carbohydrates, such as sugary desserts, pasta, potatoes, bread, and bread products.
  • Eliminate high-sugar beverages, such as juice and sodas.
  • Exercise portion control.
  • Avoid binge eating. Don’t smoke cigarettes.
  • Avoid substances not recommended by your doctor.
  • Avoid alcoholic beverages.
  • Don’t drink beverages with your meals.
  • Take a daily multivitamin.
  • Consume protein shakes or protein powder.



Gastric Bypass: Doctors recommend that gastric bypass surgery patients take a complete multivitamin, calcium with Vitamin D, iron and Vitamin C, Vitamin D, and Vitamin B12. Others may be recommended.
