Abstract
obesity is a chronic disease of metabolic and/or genetic origin related to excess body fat, the increase in body weight is associated with many co morbidities. Bariatric surgery is becoming a common procedure to control the obesity problem. However, despite the prevalence of the surgery, little is known regarding the motivation of patients who seek out these procedures, quality of nutrition and the quality of life before and after the operation. The present study aims to identify reported reasons for bariatric surgery and determine if there is a difference between male and female response regarding the motives for seeking bariatric surgery, the quality of nutrition and the quality of life before and after the operation.
Aim of the study: To assess the quality of life and the quality of nutrition among obese patients before and after bariatric surgery, to assess the degree of body weight loss and the improvement of obesity related diseases after bariatric surgery, to explore the reasons and patients’ motivation for seeking bariatric surgery and to determine all outcomes after bariatric surgery which includes benefits and complications.
Research methodology: This study was a prospective study among obese patients who had bariatric surgery in Minia hospitals in Minia city Form June 2019 to November 2019. Data were collected in four phases, the first phase was before the bariatric surgery, the second, the third and the fourth phases were a follow up assessment of these patients just after the operation, 6 months after the operation and 1.5 years after the operation consecutively. 9 patients dropped out during the study and seven patients refused to participate. Accordingly, a total 182 patients were included in the study, with response rate 91.9%. The questionnaires were administered to the patients after explaining the purpose of the study.
Results: The mean weight of the studied cases before operation was 138.8 ± 12.5 and the mean BMI was 50.4 ± 5.6 so they were morbid obesity. 55% of the cases (100 cases) underwent SASI operation, 29% of them (53 cases) underwent sleeve gastrectomy and 16% of them (29 cases) underwent gastric bypass. There were statistically significant differences between men and women response, women more likely to choose appearance (34.5% vs 0.0%, P 0.0001) as their most important factor, women were embarrassed socially about themselves (24.1% vs 2.1%, p 0.0001). Men more likely to choose medical condition (41% vs 18.4 %, P=0.02). There was highly statistically significant difference found between before operation, after 6 months and after 1.5 years regarding weight (Kg), BMI, SBP and DBP, there was highly statistically significant difference found between before operation, after 6 months and after 1.5 years regarding health problems, these health problems improved after operation. (P < 0.05), there was highly statistically significant difference found between before operation, 6 months and 1.5 years after operation regarding the occurrence of Cholecystitis, this health problem got worse after the operation. (P < 0.000), there was highly statistically significant difference between before operation, 6 months and 1.5 years after operation regarding the feeding habits of the studied group (p 0.000). There was statistically significant difference regarding food satisfaction before and after operation, the overall food satisfaction improved after 6 months and then decreased again after 1.5 year, but it was even better than before operation. (p = 0.0001). There was highly statistically significant difference found between before operation, after 6 months and after 1.5 years regarding quality of life score in all domains (p value <.05), there was an increase in all domains of quality of life score after bariatric surgery. SASI operation showed higher mean scores in physical health, psychological and social relationships domains 18 months after the operations. However, these differences not statistically significant.
