A study has found an injection to be effective in fighting obesity when given to certain blood vessels in stomach, leading to suppression of appetite. Researchers at John Hopkins University School of Medicine chose 10 healthy pigs for the obesity study as they have a anatomy very similar to humans.The pigs were injected a chemical (named sodium morrhuate) in blood vessels supplying certain parts of stomach. This reduced the amount of hunger hormone produced in pigs, ghrelin, by 60%. Lower eating levels made the pigs lose weight significantly.The procedure called gastric artery chemical embolization (GACE) would be a better option for both patients ( who can recover sooner) and doctors (as it is easy to perform).
