Gastric bypass shown to provide better results for diabetics than other types of weight loss surgery

Gastric bypass surgery may be a better option than sleeve gastrectomy similar lap-band surgeries for individuals who are severely obese and struggle with type 2 diabetes, according to a new study from the University of Wisconsin School of Medicine and Public Health.

In recent years, weight loss surgeries have become a popular option for individuals who need to lose a significant amount of weight relatively quickly. Sleeve gastrectomies, in which a portion of the stomach is removed, and lap-band surgeries are the latest development in this field, and were intended to offer patients a less invasive option.

However, the study suggests that these procedures are less effective. The researchers followed the medical records of 100 patients who recently underwent a lap-band procedure and 100 patients who received gastric bypass surgery. The results of gastric bypass surgery proved to be much more encouraging.

Of the patients who had type 2 diabetes before undergoing either procedure, 76 percent of those who received gastric bypass either resolved or significantly improved their condition, compared to 50 percent in the lap-band group.

Additionally, these participants lost significantly more weight. A total of 86 percent of the gastric bypass patients lost 40 percent or more of their excess body weight, while only 31 percent of the lap-band patients accomplished this.

"Obesity and type 2 diabetes mellitus are currently two of the most common chronic, debilitating diseases in Western countries," the authors wrote in their report. "Because it achieves greater weight loss, increased resolution of diabetes, and better improvement in quality of life, we conclude that gastric bypass has a better risk-benefit profile than laparoscopic adjustable gastric band."
