weight loss surgery

As a weight loss surgeon, the fact that weight loss surgery increases life expectancy is something that has been plainly obvious to me for the last 20 years.  Now, however, we have new data from a study spanning 40 years and including nearly 22,000 people that confirms this as fact!

These results were just published last Wednesday in the journal Obesity. It was a retrospective study out of Utah, meaning the researchers looked back at data from patients over past years. They looked at patients with and without weight loss surgery and matched patients for things such as age, sex, and BMI so they were comparing apples to apples. There were 21,837 matched surgery and non-surgery pairs and the follow up was up to a very impressive 40 years.  This study is important not only because of the large number of patients including such a large time span, but also because it involves data on American patients which may be more applicable to patients in my practice than if the data were taken from, say patients in Sweden or Africa.

Four procedures were examined (listed from most common to least common):

• gastric bypass
• gastric sleeve
• gastric band
• duodenal switch

The researchers found that patients who underwent one of these procedures were 16% less likely to die from any cause, 29% less likely to die from cardiovascular disease, 43% less likely to die from various cancers, and incredibly–72% less likely to die from diabetes!

There have been other large studies that support the data seen here, so I feel like it’s about time to shout it from the rooftops!  In the U.S., it’s estimated that only 2% of patients who qualify actually end up having weight loss surgery.  Some of this is related to lack of insurance coverage, and some to patients’ reluctance to seek out weight loss surgery.  Many patients are not even aware that, when they choose an insurance plan, it may exclude access to a surgical weight loss procedure which they qualify for medically.  Not because they don’t need it, but because language is written into their policy that says it’s not going to be covered, no matter how badly they need it.

Regardless of the reason, considering modern techniques, the complication rate for bariatric surgery procedures such as gastric bypass, gastric sleeve, Lap Band, and duodenal switch are miniscule compared to what they used to be 30 years ago.  This, given with the data we see from this study and others, should compel more insurance companies to provide coverage for these life-saving procedures and more patients to consider taking this step to be rid of the disease of obesity.
