This multicenter survey of OAGB patients in Israel and Portugal found common postoperative changes in appetite, taste, and food intolerances, with a trend of declining adherence to dietary recommendations over time since surgery.
This multicenter cross-sectional survey studied OAGB patients across two countries at three time points since surgery (1–6 months, 6–12 months, 1–5 years). Data were collected via an online survey assessing demographics, weight outcomes, nutritional behaviors, and lifestyle. Key results showed that the majority of respondents reported changes in appetite and taste, with common food intolerances to red meat, pasta, bread, and rice. Adherence to bariatric surgery eating recommendations was high in the early postoperative period but showed a trend of lower adherence in groups with longer time since surgery. Most patients followed up with surgeons and dietitians, but a minority had follow-up with psychologists or social workers. The findings suggest a need for long-term behavioral and nutritional support to maintain adherence.
