Lap Band Surgery Patients Lose More Weight

than people who use diet and exercise. Even when the diet and exercise group are under a doctor’s supervision.

I was looking around for new and interesting studies and I found this one, which is two years old, from Paul O’Brien, JB Dixon and C. Laurie entitled Lap-Band or Medical Therapy for Metabolic Syndrome. Now here is how the American Heart Association defines Metabolic Syndrome:

The metabolic syndrome is characterized by a group of metabolic risk factors in one person. They include:

  • Abdominal obesity (excessive fat tissue in and around the abdomen)
  • Atherogenic dyslipidemia (blood fat disorders — high triglycerides, low HDL cholesterol and high LDL cholesterol — that foster plaque buildups in artery walls)
  • Elevated blood pressure
  • Insulin resistance or glucose intolerance (the body can’t properly use insulin or blood sugar)
  • Prothrombotic state (e.g., high fibrinogen or plasminogen activator inhibitor–1 in the blood)
  • Proinflammatory state (e.g., elevated C-reactive protein in the blood)

People with the metabolic syndrome are at increased risk of coronary heart disease and other diseases related to plaque buildups in artery walls (e.g., stroke and peripheral vascular disease) and type 2 diabetes. The metabolic syndrome has become increasingly common in the United States. It’s estimated that over 50 million Americans have it.

So, of course, we are studying how best to treat Metabolic Syndrome and this study finds that Lap Bands are far more effective.

Aims: The primary aim of this study was to conduct a randomized, controlled trial to compare the effectiveness of standard, nonsurgical therapy for weight loss with LAP-BAND in mild to moderate obese adults (body mass index [BMI] 30–35 kg/m2).

A BMI of 30-35 is our 5’4″ woman weighing between 169 and 197. It’s our 5’10” guy weighing between 209 and 243. Not huge. Not morbidly obese, by any means. But certainly quite a bit heavier than most people can carry and be comfortable. Check your BMI here.

Methods: Participants were eligible for inclusion if they were between 20 and 50 years of age, had a BMI of 30 to 35 kg/m2, and had an obesity-related comorbid condition (including severe physical limitations or clinically significant psychosocial problems related to their obesity). Participants were excluded if they had had previous bariatric surgery or medical problems that contraindicated treatment in either study group (ie, impaired mental status or drug or alcohol addiction). In addition, participants who had undergone an intensive, physician-supervised program that used very low caloric diets or pharmaco-therapy for weight loss were also excluded.

And what happened with that group of people? Well…

The percentage of initial weight loss (~ 13.8%) was the same for both groups at 6 months. However, the surgical group continued to lose weight at the 12-, 18-, and 24- month evaluations. At the end of the 2-year study period, the surgical group had lost 87.2% of their excess weight. The nonsurgical group showed progressive weight gain after the initial weight loss described above. All of the patients who had surgery and eight of the 33 patients who were treated without surgery achieved satisfactory weight loss, defined as a loss of 25% of excess weight.

Basically, the people who had Lap Bands lost close to 90% of their excess weight. The people who were treated non-surgically, gained most of their weight back. At the end of the two year period, only 8 of the 33 non-surgical patients had lost 25% of their excess weight.

Those non-surgical patients had a pretty optimal experience for losing weight. It’s not like they were handed a 28 page pamphlet and told to knock a few pounds off. They were aggressively treated with drugs, exercise and had appointments with a physician every six weeks. From the study:

The nonsurgical program was centered on behavioral modification and included a very low caloric diet, increasing physical activity, and pharmacotherapy. After an initial intensive 6-month period of very low calorie diet (500–550 kcal/d), patients were started on 120 mg
of orlistat once a day, which was then increased to 120 mg of orlistat before all meals. All participants were seen at least every 6 weeks by a physician. All participants were instructed in appropriate lifestyle behaviors, including healthy eating habits and regular exercise for at least 200 minutes per week regardless of the study group to which they were randomized.

Even under those ideal circumstances, most people couldn’t lose the majority of their excess weight in two years, unless they had the Lap Band surgery. And that is certainly experience that I have had in my life and if you’re reading this blog, I bet you have as well.

Good to know.
