Obesity is termed as the pathology defined by excess body weight due to the increase in adipocytes. It can be visceral, close to the omentum, mesentery, and subcutaneous, accumulated in the hypodermis. It is a disease that entails metabolic, respiratory, locomotor, and cardiovascular problems, type II diabetes, cancer, and even mental problems. Established by the Body Mass Index (BMI) and defined from the relationship between weight (kg) and height (m) of individuals. In numerical terms, a person is considered obese when the BMI is equal to or greater than 30 kg/m. This retrospective study took into account the more than 30 years that the coordinator of this work has devoted to morbidly obese people and all his 47 years of experience in medicine. The first obese person of his career was 41 years old and weighed 210 kg. As soon as she arrived at the hospital, she said: “Doctor, I am here, because I need to enter a ‘workshop’, to repair my body”. From that moment on, the name “workshop” became part of a fantastic project with obese people called “Obese Workshop”. Over time, the number of patients with this comorbidity has only increased, reaching, once, the point of speaking to 325 interested parties in a single day and in the same hall. In order to achieve satisfactory results, we have established a number of tests, by which we could diagnose several reasons that cause obesity. We selected randomly 20 patients of both sexes, morbidly obese, operated in 2013. We do not take into account age, race, creed, or social status.
