Bariatric Surgery Is Effective Long-Term

Because of its effectiveness, bariatric surgery continues to be used in the fight against obesity. But while bariatric surgery does generally lead to weight loss, there has been some question as to whether obese patients who have the surgery will be healthier long-term. At least two studies demonstrate the long-term effectiveness of bariatric surgery.

A 2005 Swedish study tried to answer the above question to some extent. For example, the study went a long way toward answering the following question:  Does bariatric surgery decrease mortality? The study went a long way, because based on the study results, the answer is "yes." In fact, according to the study, bariatric surgery reduces the mortality of obese patients when the mortality of weight loss surgery patients was compared to the mortality of patients who experienced non-surgical weight loss treatments.

Investigators in the Swedish study looked at 4047 obese patients. Approximately half of the patients underwent bariatric surgery, and the other half used non-surgical methods to lose weight. At the end of ten years, there were 129 deaths in the non-bariatric surgery group and 101 deaths in the bariatric surgery group.

And a more recent study concludes that bariatric surgery can lower the risks of type 2 diabetes and high blood pressure in the future. The study looked at 1,100 adults who were severely obese. The investigators "found that those who underwent gastric bypass lost an average of 100 pounds over two years. By year 12, they'd managed to keep 77 of those pounds off." Further, the investigators concluded that "surgery patients had a much lower risk of developing type 2 diabetes -- 92 percent lower, versus obese patients who did not have surgery."

So, the above studies indicate that bariatric surgery, indeed, is effective long-term. These studies should be of interest to surgical and non-surgical weight loss providers. Drawing from these studies, providers can feel more confident when counseling patients on the pros and cons of bariatric surgery.
