Zusammenfassung. Zusammenfassung: Bei steigender Prävalenz der Adipositas und der damit assoziierten Komorbiditäten rückt die bariatrische und metabole Chirurgie immer mehr in den Vordergrund, wobei weltweit der Roux-Y-Magenbypass (= Roux-en-Y ­Gastric- Bypass, RYGB) und der Schlauchmagen (= Sleeve gastrectomy, SG) die häufigsten Eingriffe darstellen. Der erzielte Gewichtsverlust und das veränderte Essverhalten scheinen dabei nicht wie initial vermutet ausschliesslich auf einer ­mechanischen Restriktion der Nahrungspassage und / oder einer kalorischen Malabsorption der aufgenommenen Nahrung zu beruhen, sondern vielmehr auf ein komplexes Zusammenspiel verschiedenster physiologischer Wirkmechanismen zurückführbar zu sein. Ziel des vorliegenden Artikels ist es deshalb, vor dem Hintergrund des aktuellen Wissenstandes einen kurzen Überblick über die wichtigsten Wirkmechanismen der bariatrischen und metabolen Chirurgie zu liefern.

The aim of this study was to explore the impact of bariatric surgery on fat and sweet taste perceptions and to determine the possible correlations with gut appetite-regulating peptides and subjective food sensations. Women suffering from severe obesity (BMI > 35 kg/m2) were studied 2 weeks before and 6 months after a vertical sleeve gastrectomy (VSG, n = 32) or a Roux-en-Y gastric bypass (RYGB, n = 12). Linoleic acid (LA) and sucrose perception thresholds were determined using the three-alternative forced-choice procedure, gut hormones were assayed before and after a test meal and subjective changes in oral food sensations were self-reported using a standardized questionnaire. Despite a global positive effect of both surgeries on the reported gustatory sensations, a change in the taste sensitivity was only found after RYGB for LA. However, the fat and sweet taste perceptions were not homogenous between patients who underwent the same surgery procedure, suggesting the existence of two subgroups: patients with and without taste improvement. These gustatory changes were not correlated to the surgery-mediated modifications of the main gut appetite-regulating hormones. Collectively these data highlight the complexity of relationships between bariatric surgery and taste sensitivity and suggest that VSG and RYGB might impact the fatty taste perception differently.
