Study: Weight-Loss Surgery Alters Sense Of Taste, Smell
ATLANTA (CBS Atlanta) – According to a recent study, many patients have changes in their appetite, taste, and smell after weight-loss surgery.
These changes may lead to at least one positive thing and that is even more weight loss.
Researchers analyzed data from 103 British patients who underwent Rouz-en Y gastric bypass surgery.
HealthDay reports that 97 percent said their appetite changed after the surgery, while 42 percent said their sense of smell changed.
Researchers noted that 73 percent of the patients had changes to their sense of taste.
Some patients reported a newly developed dislike for certain foods. The patients that did develop a new dislike lost an average of 18 more pounds than those who did not, according to HealthDay.
The study only found an association between weight-loss surgery and sensory changes. It did not establish a cause-and-effect.
Lisa Graham, lead author on the study, told HealthDay that the sensory changes after weight-loss surgery may be due to a combination of gut hormone and central nervous system effects.
Graham went on to say that a doctor will warn a patient of the risks of loss of taste and smell when they consider a weight-loss operation.
The Centers for Disease Control and Prevention report that more than one-third of U.S. adults are obese.
