“…However, this study is one of the first of its kind measuring salt as part of a food solution and used a small sample size ( n = 14) [ 75 ]. Comparisons of taste acuity between RYGB and VSG patients suggest RYGB patients have a significantly higher threshold to sourness, translating as a lower sensitivity [ 76 ]. Measurements of bitter and umami thresholds have shown that patients have increased sensitivity post-operatively [ 77 ] as well as changes in the perceived intensity of fatty solutions [ 78 , 79 ].…”

Taste Changes after Bariatric Surgery: a Systematic Review

BackgroundAlterations in taste perception and preferences may contribute to dietary changes and subsequent weight loss following bariatric surgery.MethodsA systematic search was performed to identify all articles investigating gustation, olfaction, and sensory perception in both animal and human studies following bariatric procedures.ResultsTwo hundred fifty-five articles were identified after database searches, bibliography inclusions and deduplication. Sixty-one articles were included. These articles provide evidence supporting changes in taste perception and hedonic taste following bariatric procedures. Taste sensitivity to sweet and fatty stimuli appears to increase post-operatively. Additionally, patients also have a reduced hedonic response to these stimuli.ConclusionsAvailable evidence suggests that there is a change in taste perception following bariatric procedures, which may contribute to long-term maintenance of weight loss following surgery.Electronic supplementary materialThe online version of this article (10.1007/s11695-018-3420-8) contains supplementary material, which is available to authorized users.

“…63 In another study, post-RYGB patients demonstrated a higher sour taste threshold, and thus lower sour taste sensitivity, compared with patients who underwent VSG. 62 By contrast, Makaronidis et al . found no evidence of altered sensitivity thresholds for sweetness, bitterness, or saltiness after RYGB compared with VSG.…”

“…Some studies indicate that bariatric surgery may have subtle effects on taste detection thresholds and sweetness acceptability. 61,62 One study used a modification of the Henkin forced-choice three-stimulus technique, 63 in which subjects are asked to rate the intensity of sweet (sucrose), salty (NaCl), sour (HCl), or bitter (urea) tastes. 64 Post-RYGB patients had an increase in taste acuity for bitter and sour stimuli and a trend towards increased sensitivity to detect salt and sweet tastes as compared with their presurgical baseline.…”

Bariatric surgery is increasingly recognized as one of the most effective interventions to help patients achieve significant and sustained weight loss, as well as improved metabolic and overall health. Unfortunately, the cellular and physiological mechanisms by which bariatric surgery achieves weight loss have not been fully elucidated, yet are critical to understanding the central role of the intestinal tract in whole-body metabolism and to developing novel strategies for the treatment of obesity. In this review, we provide an overview of potential mechanisms contributing to weight loss, including effects on regulation of energy balance and both central and peripheral nervous system regulation of appetite and metabolism. Moreover, we highlight the importance of the gastrointestinal tract, including alterations in bile acid physiology, secretion of intestinally derived hormones, and the microbiome, as a potent mediator of improved metabolism in postbariatric patients.

“…Bariatric surgery seems to reverse these obesity-related alterations in taste perception (7)(8)(9)(10). However, controversy exists (11)(12)(13)(14)(15). The discrepancies between studies may be due to methodological differences, such as self-report versus direct measures and variation of the time point of assessment pre and post surgery.…”

Objective The aim of this study was to investigate the effect of bariatric surgery on sweet taste sensitivity and the hedonic evaluation of sweet, savory, and fatty food stimuli as well as associations with weight loss and food preferences assessed at a buffet meal test. Methods The detection and recognition threshold for sweet taste and the hedonic rating of sweet, savory, and fatty food stimuli were assessed before and after a preoperative diet‐induced weight loss and 6 weeks, 6 months, and 18 months after Roux‐en‐Y gastric bypass (RYGB) and sleeve gastrectomy (SG) (n = 29). Results The detection threshold for sweet taste decreased after the diet‐induced weight loss and 6 weeks after RYGB (both P ≤ 0.03). The hedonic rating of high‐fat food stimuli decreased 6 weeks after RYGB and SG (all P ≤ 0.02). Changes in the hedonic rating of high‐fat food stimuli were associated with increased preferences for high‐fat foods at the buffet meal (P = 0.03) and tended to be associated with weight loss (P = 0.05). No changes were detected for sweet and savory food stimuli. Conclusions RYGB increased sweet taste sensitivity; however, this effect was already seen after the diet‐induced weight‐loss. RYGB and SG decreased the hedonic evaluation of high‐fat food stimuli, but this effect did not translate into decreased preferences for high‐fat food.
