A new study finds that weight-loss surgery causes taste changes as well as changes with appetite and smell. The changes are said to help and encourage weight loss continuously.
The study, published in the online journal Obesity Surgery, included 103 British patients who had Roux-en-Y gastric bypass surgery. This particular gastric bypass surgery makes the stomach smaller and shortens the small intestines. According to the study, 97 percent of the patients that underwent the surgery reported appetite changes. An additional 42 percent stated a difference with their sense of smell. What was most unique about the study is 73 percent of the patients also reported a change with taste.
Majority of the patients claimed that the weight-loss surgery causes taste changes as they have developed different sensations when it comes to sweet and sour foods. Moreover, those patients also claimed changes with the tastes of meat, chocolate, pasta, rice and greasy food. In addition, many of the patients gained a new dislike or like for certain foods.
While the study found a correlation between weight-loss surgery and taste changes, it does not definitively prove that weight-loss surgery causes taste changes. Lead author of the study from Leicester Royal Infirmary Lisa Graham noted that the changes in taste and smell may stem from gut hormones and the central nervous system.
The study was conducted using the King’s Obesity Staging System that evaluates the individual in severity stages of physical, psychological, socio-economic and functional disease.
