Systematic review reveals altered taste perception post-bariatric surgery, suggesting implications for weight maintenance.
BACKGROUND: Alterations in taste perception and preferences may contribute to dietary changes and subsequent weight loss following bariatric surgery. METHODS: A systematic search was performed to identify all articles investigating gustation, olfaction, and sensory perception in both animal and human studies following bariatric procedures. RESULTS: Two 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. CONCLUSIONS: Available 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.
