Landmark Study Highlights Long-Term Success of Weight-Loss Surgery

Bariatric surgery is for life.

It sounds so easy — eat less, move more, and the excess pounds will disappear. For many people, though, it isn't so simple. Fortunately, there are other options to help you reach your goals.

At the Weight Loss Institute of Arizona, our team of highly trained surgeons understands the dangers of obesity, including an increased risk of high blood pressure, Type 2 diabetes, and heart and lung disease, among other things. Using our more than 10 years’ combined medical experience, we carefully review your health history to determine which of the many weight-loss procedures we offer could be right for you.

As many people who struggle with their weight know, diet, exercise, and appetite suppressants may help with initial weight loss, but often the numbers on the scale climb back up over the years. If these traditional methods have not worked for you, it may be time to consider a surgical weight-loss option with proven long-term success.

Can weight-loss surgery keep the pounds off?

In a landmark new study, researchers in Australia have spent 20 years examining data from more than 8,000 people who underwent laparoscopic adjustable gastric band (lap-band) surgery. Believed to be the largest and longest-running study of its kind, it found that individuals weighed on average 65 pounds less at the time of the study than before the procedure two decades earlier.

An additional review of the published literature for other common weight-loss procedures at 10 years or more post-surgery determined they, too, have been successful. Gastric bypass surgery recipients experienced an approximately 58% loss of their excess weight and people who had biliopancreatic bypass decreased their extra weight by 75%. Sleeve gastrectomy also promoted weight loss, according to the research, but long-term data was more limited.

What is lap-band surgery?

One of the more common weight-loss surgeries, the lap-band procedure involves a soft, saline-filled ring positioned around the top of the stomach. This creates a small pouch that divides the stomach into two parts, slowing the movement of food into the digestive system and restricting the amount of food that can be eaten.


Adjustments may be made to the band by increasing or decreasing the amount of saline. Since the surgery is done laparoscopically with only small incisions, it is less painful and has a shorter recovery time than other bariatric surgery options. At Weight Loss Institute of Arizona, we use the LAP-BAND® System for lap-band surgery.

What is gastric bypass surgery?

Also called Roux-en-Y, gastric bypass surgery creates a small pouch from the stomach and a new route to the small intestine. After the procedure, food enters the pouch and bypasses the remainder of the stomach and initial section of the small intestine. Weight loss occurs due to the smaller capacity of the new stomach and reduced calorie absorption during digestion.

What is biliopancreatic bypass?

In a biliopancreatic bypass, about 80% of the stomach is removed and the majority of the intestine is bypassed. This procedure encourages weight loss by limiting the amount of food that can be eaten and reducing nutrient absorption.

What is sleeve gastrectomy?

A sleeve gastrectomy involves the removal of part of the stomach and re-forming of it into a tube shape to restrict the number of calories the body absorbs. It is essentially the same as the first part of the biliopancreatic bypass.
