The Effect of Nutritional and Behavioral Attitude Change on Biochemical Parameters Before and After Bariatric Surgery in Obese Individuals

Aim: The purpose of this study is to observe the effects of changes in nutritional and behavioral attitudes on biochemical parameters of patients undergoing bariatric surgery throughout the preoperative and postoperative. Materials and Methods: This study was conducted with 27 female patients who volunteered to participate in the study and applied to Samsun Anadolu Hospital General Surgery Clinic for bariatric surgery between February and March 2021. The Nutritional and Behavioral Attitude Scale in Bariatric Surgery Patients was applied to patients preoperative and postoperative 1st and 6th months, and their biochemical parameters were evaluated. In blood analysis, the hospital’s routine fasting blood glucose, alanine aminotransferase (ALT), aspartate aminotransferase (AST), C-reactive protein (CRP), creatinine, thyroid stimulane hormone (TSH), vitamin B12, calcium and iron levels were assessed. Results: There was no significant difference between the nutritional attitudes of the individuals according to the nutritional and behavior attitude scale applied to obese individuals (p>0.05), nevertheless the pre- and postoperative cigarette and alcohol consumption decreased (p<0.05), and the number of meals and water consumption increased. The changes in iron, vitamin B12, and calcium levels before surgery, as well as at 1 and 6 months after surgery, are not statistically significant (p>0.05). Significant changes in CRP and creatinine levels were observed (p=0.010 and p<0.001, respectively). Conclusion: The changes in nutritional and behavioral attitudes observed within one month after bariatric surgery have positive effects on individuals’ biochemical parameters.
