DOCTORS CONDUCTING A new weight loss study used gas to freeze a nerve in the back that carries hunger signals to the brain, lowering patients’ appetite and promoting weight loss…
In the study, the men and women were sedated and doctors inserted a needle into their backs guided by a CT scan. They directed the needle to a specific nerve, the posterior vagal trunk, and froze the needle and surrounding nerve. The procedure degenerates part of the nerve connected to the brain and stops the connection between the two. The procedure takes about 30 minutes and is painless.
One hundred percent of the subjects reported a decrease in appetite. After 90 days, the average weight loss was 3.6 percent of initial body weight and the average loss of excess BMI was 14 percent.
