A group of scientists at Johns Hopkins have figured out a non-invasive way to lower appetite by preventing the body from manufacturing the "hunger hormone" thus resulting in weight loss.

This discovery holds utmost importance as it could lead to a potential solution for people who struggle with obesity. Dr. Aravind Arepally of the John Hopkins University School of Medicine created this new procedure known as gastric artery chemical embolizatioin, or GACE.

The scientists blocked production of a hormone called ghrelin in pigs, which creates the sensation of hunger. The procedure works by injecting a chemical into blood vessels that feeds the top section of your stomach, called the fundus.

Pigs that underwent the procedure stopped gaining weight, the study found. The researchers used sodium morrhuate to dissolve the blood vessels that feed the fundus to reduce the hunger. If a similar procedure could be done safely in humans, it may help people fight obesity with a non-invasive alternative to bariatric surgery now done to reduce stomach size, researchers said.
