abstract = {Background: Bariatric surgeries, specifically laparoscopic
sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB),
are a common intervention for morbid obesity, significantly
affecting food tolerance and quality of eating.
Understanding these changes is crucial for improving
postoperative care and long-term success. Methods: This
observational study at University Hospital Mannheim involved
91 patients, aged between 18 and 65 year, who underwent SG
or RYGB between 2009 and 2019. Food tolerance was assessed
between 25 days and 117 months after surgery using the
validated score by Suter et al. (Food Tolerance Score, FTS)
and an additional score evaluating tolerance to specific
food groups and quality of life. Data on body composition
were collected through Bioelectrical Impedance Analysis
(BIA) at follow-up visits. Statistical analyses included
linear mixed models to analyze the association of food
tolerance with body composition changes. Results: The FTS
indicated moderate or poor food tolerance in $62.6\%$ of
patients, with no significant differences between SG and
RYGB. Considering the results of the additional score, food
groups such as red meat, wheat products, raw vegetables,
carbon dioxide, fatty foods, convenience food, and sweets
were the most poorly tolerated food groups. A total of 57 of
the participants had a baseline and follow-up BIA
measurement. Postoperatively, a significant reduction in
body weight and BMI as well as in BIA parameters (fat mass,
lean mass, body cell mass, and phase angle) was found.
Quality of life improved after bariatric surgery and
$76.9\%$ rated their nutritional status as good or
excellent, despite possible food intolerances. Conclusions:
Bariatric surgery significantly reduces weight and alters
food tolerance. Despite moderate or poor food tolerance,
patients reported high satisfaction with their nutritional
status and quality of life. Detailed food tolerance
assessments and personalized dietary follow-ups are
essential for the early detection and management of
postoperative malnutrition, ensuring sustained weight loss
and improved health outcomes.},
