bariatric surgery, Roux-en-Y gastric bypass, sleeve gastrectomy, morbid obesity, weight reduction, and long term
The purpose of this research is to show the efficacy of Roux-en-Y gastric bypass and sleeve gastrectomy as compared to traditional diet and exercise models. Morbid obesity is related to increased blood pressure, incidence of diabetes, high cholesterol, and incidence of obstructive sleep apnea, all of which contribute to increased incidence of myocardial infarction, stroke, and vascular compromise. Finding ways to combat morbid obesity has resulted in invasive surgical techniques because traditional diets and exercise work infrequently and often fail. Systematic reviews, meta-analysis, randomized controlled trials, and retrospective studies were found using the database of CINAHL, SportsDiscus, PsycInfo, Embase, and PubMed. All of the studies were published no later than 2014 and used human adult subjects ages 19-65. The studies reviewed show that bariatric surgery is a safe, effective obesity treatment with a low risk of post-operative complications and mortality related to surgery. The reviewed studies found that patients who undergo the Roux-en-Y gastric bypass can lose 80% or more of excess weight, and those who undergo sleeve gastrectomy can lose 60% or more of excess weight. The research also shows that the bariatric surgeries discussed here help people maintain weight loss for up to ten years.
