Abstract
INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) modifies gastrointestinal substances that control hunger and satiation via the brain-gut axis. A potential mechanism implicated in weight loss is the shift in food preferences. Our aim was to assess changes in taste preferences and their relationship to weight loss. METHODS: This is a prospective longitudinal observational study in 100 consecutive LSG patients. Questionnaire with photographs of tastes was administered before surgery, at postoperative (PO) day 6 and PO month 6. Participants asked to rate each item in terms of desire to consume on a 5-point Likert scale. RESULTS: Preoperative demographics are as follows: 77 women/23 men, mean age 40.8 ± 12 years, and mean BMI 42.46 ± 6.7 kg/m2. Mean 6-month PO % total body weight loss (%TBWL): 24 ± 6.2%. Preferences for bitter, salty, umami, fatty, sour, spicy, and sweet decreased significantly from baseline to PO day 6 (p < 0.001) and to PO month 6 (p < 0.002). Preferences of water (4.22) did not change significantly; red wine (1.8) and cigarettes (1.86) decreased significantly at PO day-6, but returned to baseline range at PO month 6. The highest changes of preferences in 6 months were observed for fatty (delta = 1.58) and sweet (delta = 0.95), (p < 0.002). Preference for salty at 6 months negatively correlated with %TBWL (p = 0.01). CONCLUSION: LSG seems to be associated with a rapid and sustained decrease in preferences for all core tastes, detectable already at PO day 6. Preferences for sweet and fatty food undergo the highest decline, whereas preferences of water, red wine, and cigarette remain unchanged. The decrease in salty preference seems to correlate with 6-month %TBWL. Further studies are needed on the long-term impact of taste changes after LSG.
