Abstract:

Introduction: One of the consequences of bariatric surgery is food intolerance, usually accompanied by nausea, vomiting, diarrhea, constipation and dumping syndrome. An imbalance in the intestinal microbiota that produces harmful effects to the patient is called intestinal dysbiosis, which can cause diarrhea, constipation, worsening symptoms of lactose intolerance and other symptoms. Objective: To investigate the association between the risk of intestinal dysbiosis and food intolerance in the postoperative period of patients undergoing bariatric surgery. Materials and Methods: This is an observational, cross-sectional study conducted with patients who underwent bariatric surgery within the scope of the Sistema Único de Saúde. Data were collected from medical records and a semi-structured questionnaire containing questions about food intolerance was applied, the Bristol scale was used to analyze stool consistency and a questionnaire to identify the risk of dysbiosis was applied. Results: The sample consisted of 32 patients, 84.4% of whom were female. Of those evaluated, 81.3% stated that the quality of the food was excellent or good and 43.8% of the sample had food intolerance. The most reported symptoms were diarrhea (42.8%) and vomiting (28.6%). The dysbiosis risk questionnaire showed that 37.5% of the sample had a high risk of dysbiosis. There was no statistical difference in the association between the risk of dysbiosis and food intolerance. Conclusion: There was a moderate prevalence of food intolerance and a low prevalence of risk of intestinal dysbiosis. The results showed that risk of dysbiosis was not related to a food intolerance.
