For those that have tried and failed to lose weight with traditional weight loss strategies, the final step in promoting significant weight loss is bariatric surgery.
Bariatric surgery, as a field, has been shown to promote substantial weight loss in patients that are able to follow the dietary practices, and while it is not magic, a medically significant percentage of those that undergo weight loss surgery successfully lose enough weight to control many of their obesity-related diseases.
One such surgery is known as the Lap Band. The Lap-Band is a silicone band that is wrapped around the top portion of the stomach. It reduces the size of the stomach so that you feel full faster.
The Lap Band has long been a popular procedure. Unlike most other surgical options, such as gastric sleeve and gastric bypass, the Lap-Band is reversible. It does not require any permanent changes to your stomach, and it can be removed with little risk of long-term consequences.
But for many, the question is still about efficacy. How much weight loss can you expect after the Lap Band procedure?
It is important to note that all bariatric surgery outcomes still depend on the patient. Those that are unable to make the dietary and lifestyle changes necessary to promote weight loss will still struggle to lose weight. This is especially true of Lap Band, where those that overeat or fail to adjust to their band may be at risk for pouch stretching. Pouch stretching increases hunger and allows more food to sit in the stomach.
However, most individuals that undergo Lap Band surgery do see positive results to their weight loss efforts. How much depends on the individual but we can report an average expected weight loss based on science. The following are several studies, along with their reported average weight loss after LapBand:
50% excess weight loss is considered significant and can help reduce or cure many obesity-related diseases. But the question is not just how much weight you can expect to lose. It is also how it compares to other procedures. Although there are several experimental weight loss procedures, there are three main alternatives to Lap Band: Gastric Bypass Surgery, Gastric Sleeve Surgery, and Gastric Balloon.
Many individuals use the gastric balloon to prepare for the Lap Band and potentially improve the safety of the surgery. Because the gastric balloon is a temporary procedure, results may not be permanent, but EWS% was 26% in one study. The gastric balloon may be considered a temporary option to lose weight before surgery but does not compare to Lap-Band, gastric sleeve, or gastric bypass in total weight loss.
One of the challenges in assessing Lap Band results is including or excluding patients that have their bands removed. It is estimated that as many as 25% to 50% of Lap-Band patients have their Lap-Bands either removed or replaced with a different form of bariatric surgery. Nevertheless, the 50% baseline for those that continue to follow post-surgical guidelines and do not have their Lap-Bands removed is considered a high enough percentage to help reduce chronic obesity-related diseases.
