LAP-BAND® System Results
Thousands of patients. Millions of pounds. Real, lasting weight loss results.
There are two main ways people try to lose weight — the fast way, and the healthy way. Of course, the fast way may seem a dream come true. But like your dreams at night, this kind of weight loss doesn’t last. Using the LAP-BAND® System, thousands of people have safely and effectively achieved healthy, lasting weight loss. In fact, a clinical study (N=100) showed that LAP-BAND® System patients averaged up to a 59% reduction in excess weight after eight years.1† And, another study showed that after the first year, 94.1% of patients were satisfied with the LAP-BAND AP® System (N=272).2‡
What you can expect
The LAP-BAND® System is powerful tool that can give you control and help you lose weight. However, it’s also important to set realistic achievable weight loss goals from the start. Although weight loss of up to three pounds a week is possible, LAP-BAND® System patients generally average a healthy one-to-two pound reduction a week.3 Best of all, once patients meet their target weight, they often maintain it for years.
Slow and steady = healthy and lasting
In addition to being temporary, losing weight too quickly can create health risks and lead to other problems. With the LAP-BAND® System, the main goal is gradual, steady, and lasting weight loss that may prevent, improve, or resolve health problems associated with severe obesity.1,4,5
With LAP-BAND® you will lose less lean muscle mass and bone mass than with gastric bypass.6,7 This means that most of your weight loss after LAP-BAND® surgery is due to excess fat loss and that you will maintain more of the lean muscle mass you need to keep your metabolism working effectively which will help you to reach and maintain your weight loss goal. There is less risk of excessive bone loss leading to bone disease such as osteoporosis than with gastric bypass.6,7 Gastric bypass and sleeve gastrectomy patients often need to take supplements to offset higher levels of lean muscle mass and bone density loss.
Proven Results
In an ongoing study (N=500), the LAP-BAND® System was shown to provide significant reductions in weight. After 12 months (N=276)8:
- The mean Excess Weight Loss (EWL) was 47.5%†
- The mean reduction in Body Mass Index (BMI) was 8.9 points†
- At 12 months there was no sign of weight regain or hitting a plateau (weight loss leveling off)
In separate studies each evaluating one obesity-related health condition, weight loss with the LAP-BAND® System was shown to help improve and resolve conditions such as asthma (93%; N=32), Type 2 diabetes (90%; N=50), sleep apnea (93%; N=123), gastroesophageal reflux (90%; N=48), and hypertension (79%; N=34).9-12§
In an international study (N=272) reviewing long-term results of multiple studies over a 5-year period, LAP-BAND® System patients lost 55% of their excess weight.1,12†
In a separate study (N=276), comparable weight loss results (43% EWL) with the Realize™ Band were shown after three years.14
For those with a Body Mass Index (BMI) between 30 and 40, a new study (N=149) shows that the LAP-BAND® System provides significant results.15
In the first 12 months (N=143):
- The mean Excess Weight Loss (EWL) was 64.5%
- The mean reduction in Body Mass Index (BMI) was 6.5 points
- The mean reduction in waist circumference (in inches) for men was 6.1 inches; women 5.9 inches
- Weight loss was maintained at year 2
‡ Patient satisfaction data was collected during the APEX study, an observational study that used a global questionnaire to ask patients it they were: very satisfied, satisfied, indifferent, or dissatisfied with their LAP-BAND AP® experience. 84.1% of patients completed the questionnaire at their 48 week follow-up visit (272/323). Allergan data on File; October 2009.
†The LAP-BAND® System was approved in the United States on the basis of a nonrandomized, single-arm study (N=299). Significant improvement in percent of excess weight loss vs. baseline was achieved at 12 months (34.5%), 24 months (37.8%), and 36 months (36.2%). The mean reduction in BMI was 8.5 at 12 months, 9.4 at 24 months and 8.8 at 36 months.13
§Based on 4 studies. Asthma (N=32; resolved: 34%; improved 59%); Type 2 diabetes (N=50; resolved: 64%; improved 26%); sleep apnea (N=123; resolved: 93%); gastroesophageal reflux (N=48; resolved: 76%; improved: 14%); hypertension (N=34; resolved: 44%; improved: 35%).9-12
Weight loss with the LAP-BAND® System is comparable to standard gastric bypass at 3 years and beyond1

Average excess weight loss is comparable over time.
LAGB = Laparoscopic adjustable gastric banding
*Laparoscopic adjustable gastric banding using the LAP-BAND® System and another adjustable gastric band. Comparison is based on pooled data from 43 peer-reviewed reports involving at least 100 patients at entry and providing at least 3 years of postoperative data. Data at the five-year point is reflective of N=176 patients for RYGB and N=640 patients for LAGB.1
