Position on Weight Loss Surgery

The International Size Acceptance Association (ISAA) generally does not support the use of bariatric or weight-loss surgery (WLS). ISAA recognizes that not all people are accepting of themselves at whatever size they happen to be and that some people view WLS as an alternative to the perceived health risk associated with increased weight, especially after diets and other methods of weight loss fail.

ISAA cannot support the option of WLS, even as a very last resort. ISAA believes that long-term studies need to be performed to determine whether or not WLS increases the chances of mortality (death) for potential recipients who are already in ill health.

While ISAA acknowledges that WLS can result in some weight loss (10% on average), ISAA cannot support the use of WLS for the following reasons:

  1. WLS recipients can and often do regain the weight they lost, plus more, usually within five to ten years. For example, It is possible to stretch stomach tissue left after stapling, which defeats the purpose of the procedure.
  2. Potential WLS recipients are not fully informed about the risks and side-effects of WLS, which can include but are not limited to painful gastrointestinal distress, leaking of gastric juices into the chest cavity, infection, deterioration of teeth (erosion of enamel caused by repeated vomiting), flatulence, mineral and nutrient deprivation (especially potassium), uncomfortable and highly odorous bowel movements and/or loose stools.
  3. Rapid weight loss, whether from dieting or from WLS, affects muscle more than fat, including heart muscle. The long term results of the procedure could lead to death from heart-related complications.
  4. WLS requires that the recipients eat smaller meals but more meals throughout the day. If a person consumes more than their stomach has been reduced to, they vomit the rest, which can lead to bulimic behavior. The alternative is eating less, which can lead to anorexic behavior. In addition, WLS recipients will be more inclined to obsess about food, since they have to eat much more often with seriously restricted amounts.
  5. Finally, if WLS procedures were not sanctioned by insurance companies, less people would have the procedures done, since the procedures are expensive. Insurance companies sanction the procedures because there is some recorded success rates (though with side-effects such as listed in 2.), as opposed to straight dieting, which has a 98% failure rate. ISAA does not support weight loss dieting nor does it view WLS as a "necessary alternative" to weight-loss dieting.

The International Size Acceptance Association believes in educating people that one can be healthy at any size, even a large size. ISAA's Mission is to promote size acceptance and help to end size discrimination through means of advocacy and visible, lawful actions. Based on the information at its disposal, ISAA is not aware of any instance where the benefits of WLS outweigh the short and long-term risks and consequences of such procedures.

ISAA welcomes all people to participate in ISAA's activities, whether or not they have had WLS or are planning to have WLS. For clarification, ISAA's policy is against the surgery, not the people who have the surgery.
