Given the wide range of reported weight loss following lap band surgery, we have to wonder about the legitimacy of some of the studies. One thing is for certain… regardless of the study source, every surgeon experiences a huge range of weight loss results from patient to patient.

While the average long-term percentage of excess weight lost is around 50% (for example, someone who is 100 pounds overweight can expect to lose 50 pounds on average), your lap band surgery results could be as good as 82% or as bad as 25% or lower of excess weight lost.

To illustrate the potential degree of variation, following are the mean percentages of excess weight lost over the short and long-term from 8 separate studies…

Lap Band Surgery Results - The Good News

First, it is possible to lose a significant amount of weight with lap band surgery. And as one of the above studies shows, this applies to both morbidly obese patients (body mass index from 40 to 49.9) and super obese patients (BMI at or above 50).

Lap band surgery also has extremely low mortality rates. Compared to the already low mortality rate of 0.135% for all types of bariatric surgery, the lap band mortality rate is even less at around 0.09%.1,2

Regarding the improvement or elimination of obesity health problems (also called “co-morbidities”), lap band surgery results in…

  • Complete resolution of all co-morbidities in 24% of patients3
  • For patients with 3 or more co-morbidities, 100% of them reduce their number of co-morbidities to 2 or fewer3
  • Remission of type 2 diabetes in some patients
  • Major improvements in other co-morbidities, including5:
    • Arthritis
    • Asthma
    • Depression
    • Gastroesophageal reflux disease (GERD)
    • Hyperlipidemia
    • Hypertension
    • Joint and back pain
    • Sleep apnea
    • Stress incontinence
  • Large reduction in the use of medication5
  • Significant improvement in Quality of Life score5

Despite all of the positives, there are a couple of big reasons that you might want to consider a different type of bariatric surgery…

Lap Band Surgery Results - The Bad News

First and foremost is the extremely high rate of minor or annoying lap band problems and lap band complications which have been shown to occur in as many as 33% of patients.6 Problems range anywhere from your body simply not tolerating the band (leading to vomiting or an ongoing feeling of discomfort) to band slippage that can require reoperation. This leads us to the other big negative…

The rate of lap band patients requiring gastric band removal is high.  It has been shown to occur in as many as half of all patients.6 Reoperation can be the result of not enough weight being lost or complications that require lap band removal.

See our Lap Band Revision Surgery page for all of your revision options.

When comparing the good and the bad lap band surgery results, it’s important to recognize the impact your actions can have.

For example, lap band patients who attend support groups lose noticeably more weight than patients who go it alone.7

Comparing Lap Band Surgery Results to Other Procedures

To sum things up, lap band surgery results in fewer serious complications and a lower mortality rate than other procedures. It's also reversible whereas other procedures (generally) are not.

But lap band surgery is also associated with less weight loss, a higher rate of minor complications and a higher rate of reoperation.
