Repercussões da cirurgia bariátrica na qualidade de vida, no perfil bioquímico e na pressão arterial de pacientes com obesidade mórbida

Abstract

The indication of bariatric surgery (BS) for weight loss and reduction of obesity-related comorbidities is increasing. The objective of this study was to analyze the repercussions of BS on quality of life (QOL), biochemical profile, and blood pressure (BP) of morbidly obese individuals at three different moments: one month before, three months after and six months after BS. The sample consisted of 42 morbidly obese individuals from the BS program of a hospital in the city of Juiz de Fora – MG, Brazil. They were randomly divided into intervention group (IG, n=21) and control group (CG, n=21). The IG underwent surgical intervention and the CG was instructed to maintain the usual daily tasks throughout the study period, besides receiving nutritional monitoring. The QOL, biochemical profile, and BP were evaluated through the SF-36 instrument, laboratory blood tests obtained in the patients’ medical records, and with the sphygmomanometer and stethoscope, respectively. The results showed a reduction in the biochemical variables HDL, LDL, VLDL, cholesterol, triglycerides, glycated hemoglobin, glucose, systolic blood pressure, and diastolic blood pressure in the IG 6 months after surgery. There was a significant improvement in the variables related to QQL, except in the emotional aspects. It can be concluded that BS can positively affect most QOL domains, improve the biochemical profile and BP of morbidly obese patients 3 and 6 months after BS.
