Determinant Factors and Possible Causes Associated with the Success or Failure of Loss of Excess Weight (%Pep) in Patients Submitted to Bariatric Surgery

Abstract

OBJECTIVE: to know the reasons for the success or failure of excess weight loss in patients undergoing bariatric surgery, and its association with surgical time, quality of food consumption and physical activity. METHOD: Female patients were evaluated, with surgical time of 2 -7 years, older than 18 years, without comorbidities seen at a Public Hospital in S#xE3;o Paulo. As a success criterion for surgery, the value of the percentage of excess weight loss (% PEP) greater than or equal to 50. For possible causes of failure, an analysis of the frequency of qualitative consumption of food groups was carried out according to the Fisher test. and for the analysis of the practice of physical activity, the Chi-square test was used. RESULT: 45 patients were divided into two groups (G1gt; PEP n.31) and (G2 lt;PEP n.14). There was no statistical difference regarding age and surgical time. As for the surgical time and PEPgt; 50 aged 2 -3 years (66%), 4 years (81%) and 5 - 6 years (50%). In the food groups, G2 was found to be significant in the butter, white bread, soft drink and coffee with sugar. There was no difference in activity, however, in G1 who did not practice activity, 46% had 4 years of surgery and in G2 who practiced activity, 37.5% were 5 years old, which represents a relationship between surgical time and quality in the practice of the activity. CONCLUSION: In order to guarantee long-term postoperative success, the monitoring of a multidisciplinary team is essential.
