Taste Changes With Bariatric Surgery

Completed

Conditions studied: Taste, Altered

In brief

It is commonly believed that a link exists between BMI and taste perception. One group of researchers observed that women who are obese experience reduced taste sensitivity when compared to normal-weight controls. Others have compared taste sensitivity between lean and obese subjects and found no significant differences. The inconsistencies in these studies demonstrate how much variation in taste sensitivity is possible when different factors are applied in research. Throughout several studies, one element remains constant - bariatric surgery causes appetite aversions. These changes in appetite and food preference likely have a large influence on the overall magnitude of post-surgical weight loss. Although many studies have investigated the changes in taste preference after bariatric surgery, few, if any, have focused on changes in sweet taste perception.
