Freezing Hunger-Signaling Nerve May Help Lower A Person’s Appetite

reports that “in a new pilot study,” physicians “have shown that freezing the nerve that carries hunger signals to the brain may be able to lower a person’s appetite and help them lose weight.” The findings were presented at Society of Interventional Radiology’s 2018 Annual Scientific Meeting. The researchers sedated the participants “and inserted a needle into their backs; using CT guidance, they directed the needle to the posterior vagal trunk.” This “needle was filled with a gas that froze the needle and the surrounding nerve – a process that degenerates the part of the nerve connected to the brain and stops the signaling between the two.” http://time.com/5206249/weight-loss-freeze-hunger-signals/
