Effectiveness of Bypass and Sleeve Bariatric Surgical Methods in Weight Reduction

Abstract
Obesity is a chronic disease described by the large amount of body fat that leads to an increase in Body Mass Index (BMI). It is subdivided into three levels, being grade I with a BMI between 30 and 34.9 kg/m2, grade II between 35 and 39.9 kg/m2 and grade III or morbid obesity with a BMI above 40 kg/m2. Aiming at reversing the morbid condition caused by the disease, the bariatric surgical technique presents itself as the most effective option to contain grade III obesity, as well as the associated co morbidities. The objective of surgical techniques is to improve the quality of life of the obese, reducing both physical and psychosocial problems. As endocrine disease is related to several co morbidities, such as high blood pressure, sleep apnea and even some types of cancer, it is necessary to carry out an investigation into the surgical technique to be applied as well as its effectiveness during and after the surgical procedure.
