Abstract
The purpose of this study is to evaluate the food intolerance after banded Roux-en-Y gastric bypass (RYGB), correlating the data of food ingestion. METHODS: This is an observational prospective study, which evaluated the individuals before and 3, 6, and 12months after banded RYGB. We performed an anthropometric evaluation and an assessment of the habitual food ingestion and applied a food tolerance questionnaire. RESULTS: The study group was comprised of 75 individuals, 89% of them female, with a percentual weight loss of 29.73 ± 6.79%. The observed results were that food intolerance increased over time and 1year after surgery, only 2.7% reported to ingest any type of food, while the greatest difficulty was related to red meat (80%). Regarding vomits, after surgery, this proportion significantly increased after 3, 6, and 12months. Preoperatively, the mean protein ingestion was 98g, which decreased to 50g after 3 and 6months and to 51g after 12months. As a conclusion, food intolerance significantly increased following banded RYGB, leading to a crescent dissatisfaction regarding food and an increase in the vomits frequency.
