Knowing the quality of life of obese patients before and after bariatric surgery.


A cross-sectional and prospective study that included 16 obese patients who underwent bariatric surgery. The survey instrument was the Whoqol-bref translated and validated for the Portuguese language. Data were collected before and after the bariatric surgery. The SPSS 19.0 was used for data analysis with application of the McNemar's test for related samples, considering p<0.05 significant.


Before surgery 25% of participants considered their quality of life and health as bad or very bad, showing dissatisfaction. After surgery, all assessed their quality of life and satisfaction with health as good or very good. The percentages found in relation to negative feelings were better; it was observed that 62.5% did not express negative feelings anymore or only sometimes had these feelings.


The results showed that the quality of life, health, feelings, satisfaction and ability to do things has improved after bariatric surgery.
