Who should have gastric bypass surgery?

If you lose 100 pounds, you’ll gain 100% in self-confidence and health. You’ll dramatically reduce your risk for heart attack and stroke, normalize your blood sugar, slash cancer risks, ease or prevent osteoarthritis, and protect your brain from dementia. Not everyone can do it on their own, even with programs and support from friends and family, and weight-loss surgery is a solution for some. If you are currently at risk of life-threatening health problems because of your weight, it may be smart to opt for bariatric surgery.

The stomach-stapling (gastric bypass) procedure is for men who are more than 100 pounds overweight, women who are more than 80 pounds overweight, or people who are less overweight but who also have diabetes, heart disease, or sleep apnea. But this is not a “get healthy in an instant” scheme. To really get healthy long-term, after the surgery you have to change your eating patterns and get up and get moving.

Weight-loss surgery has other positives and negatives, too. It often cures sleep apnea, gastric reflux disease, and other ailments, and some studies indicate that afterward more than 60% of folks see normalized glucose levels. That said, more recent research indicates that only 41% of patients who had gastric bypass surgery, 26% who had gastric sleeve surgery (the surgical removal of part of the stomach), and 7% who had adjustable gastric banding were “cured” of diabetes long-term. It's also important to remember that any surgery has risks, from anesthesia risks and infection to unforeseen complications.

If you opt for weight-loss surgery (after going through a screening and making sure the doc you choose is a real pro at the procedure), you’ll also need to renovate your life the old fashioned way with food changes and exercise.

If you are severely overweight (more than about 100 pounds overweight) and have tried a medical weight loss program and have not maintained the weight loss, you should consider gastric bypass surgery.   If you have other metabolic disease in addition to being overweight, like diabetes, severe blood pressure problems or uncontrolled cholesterol, you should consider gastric bypass.

It is important to remember that the weight loss is variable to surgery but the best results over a long period of time are for gastric bypass, also called roux en y gastric bypass.  The other forms of weight loss surgery either do not have a good weight loss over time or have more potential complications.

It is also important to remember that you may not lose all of the weight that you want to lose, even with surgery.  It is important to always consider an adjunctive medical weight loss program if your weight loss has stalled or mild regain has started.
