The incidence of obesity in the U.S. is alarming. There are serious comorbid conditions associated with morbid obesity. These include hypertension, diabetes type-2, and sleep apnea. Although much money and effort is spent on weight loss programs, only 5% of the people meet with success.

This study is a retrospective examination of outcomes of a bariatric surgery program. Charts were reviewed between the years of 2000 and 2003. The population included over 100 patients who had Roux-en Y gastric bypass in a town in the Western United States.

The variables examined were the resolution of hypertension, diabetes type-2, and sleep apnea; weight loss trends; and incidence of complications. After Roux-en-Y gastric bypass surgery weight loss was found to be significant. The comorbidities were reduced postoperatively. Diabetes and hypertension were found to have statistically significant reductions. Sleep apnea reduction was not found o be statistically significant. In all complications examined, the incidence was higher than those found in the literature except pneumonia and wound infection.
