- Purpose: Bariatric surgery effectively treats severe obesity, leading to significant weight loss and improved comorbidities. However, many patients experience postoperative alterations in taste perception, affecting food selection and eating behavior. This narrative review examines the current understanding of taste perception changes following bariatric surgery, including patterns, potential mechanisms, impact on weight loss outcomes, and implications for patient care.
Current concept: Changes in taste perception are frequently reported after bariatric procedures, with prevalence rates from 36% to 72%. Common alterations involve decreased preference and increased sensitivity to sweet and fatty tastes, potentially leading to reduced calorie intake and healthier food choices. Persistence of these changes varies and may depend on surgery type, with Roux-en-Y gastric bypass patients often experiencing more substantial effects than sleeve gastrectomy patients. Potential mechanisms include alterations in gut hormone secretion (e.g., GLP-1, peptide YY, ghrelin), modifications in neural pathways (e.g., vagus nerve), and shifts in the gut microbiome. These factors may collectively influence taste sensitivity and preferences, contributing to weight loss outcomes. Altered reward processing may reduce the appeal of high-calorie foods.
Conclusion: Alterations in taste perception are common after bariatric surgery and may significantly impact dietary behaviors, weight loss, and quality of life. While exact mechanisms are not fully understood, changes in gut hormones, neural pathways, and microbiota are likely involved. Patient counseling and postoperative management of bariatric surgery patients should address potential changes in taste. Further research is needed to elucidate the long-term impacts of taste alterations on weight-loss maintenance and nutritional status.

Abstract
PDF
Bariatric surgery is considered one of the most effective methods of achieving long-term weight loss in morbidly obese patients. Nevertheless, bariatric procedures are associated with a number of complications, and nutrient deficiencies can lead to deleterious consequences. Furthermore, the diet of patients prior to bariatric surgery is often of poor nutrition quality that does not meet the recommended dietary guidelines for micronutrient intake. Therefore, optimization of the postoperative nutritional status should begin before surgery. This review covers the essential information about micronutrient management in patients before and after bariatric surgery.
