Gastric Bypass Surgery

Gastric bypass surgery – or Roux-en-Y – makes your stomach smaller and reduces the amount of calories and nutrients your body can absorb. As a result, you feel fuller quicker and will begin to lose weight. This surgery is one of most effective procedures to help you maintain or lose weight.

What Is Involved with Gastric Bypass Surgery?

Surgeons at Banner Health remove part of your stomach and leave a small section about the size of a small egg. It is called Roux-en-Y surgery because the connection between the intestines and the stomach tube looks like the letter Y.

Advantages of Gastric Bypass Surgery

The surgery makes you feel full very quickly when you eat. Weight loss is just one of the advantages of gastric bypass surgery, including:

  • More initial weight loss than LAP-BAND® surgery
  • No foreign objects are placed inside your body
  • No need for adjustments to make your stomach smaller

Disadvantages of Gastric Bypass Surgery

As with any surgery, please be aware there are risks and complications, including:

  • Blood clots, blockage or leaks
  • Bowel blockage
  • Fistulas (abnormal connections between internal body parts)
  • Hernia, holes, or sores
  • Gallstones and gallbladder disease
  • Nausea or vomiting from food
  • Weakness, sweating, anxiety and heart palpitations from sugars and sweets
  • If you overeat, you can stretch your stomach opening (stoma) or pouch

After Gastric Bypass Surgery

After your gastric bypass surgery at Banner Health, you should continue to lose weight or maintain your weight loss if you eat a healthy diet and exercise regularly. Include a multivitamin in your diet and mineral supplements, such as iron, calcium, Vitamin B12 and folic acid.

It is important to follow-up with a dietitian and your doctor on a long-term basis to make sure you’re eating a healthy diet and getting enough exercise. We also recommend avoiding smoking. It puts you at high risk for infection, blood clots, slow healing and other life-threatening complications.

You’re invited to attend our free support groups both before and after your surgery.
