According to scientists at Washington University School of Medicine in St. Louis, interrupting nerve signals to the liver can prevent diabetes and hypertension in mice.

Mice were treated to become diabetic with glucocorticoids, a class of steroid hormones characterized by an ability to bind with the cortisol receptor. Once diabetes was established, the researchers surgically removed the vagus nerve. The vagus nerve is the only nerve that starts in the brainstem and extends all the way down to the abdomen. More impressive is the fact that once the nerve was removed from the diabetic mice, insulin resistance and high blood pressure was prevented or reversed. This is an interesting discovery because people with asthma, arthritis, and organ transplants often rely on steroid treatments. It just so happens that many of them go on to develop insulin resistance.

Don't go ripping your vagus nerve out just yet. A fun fact about the vagus nerve is that it's name is taken from the Latin word meaning "wanderer". The vagal nerve pathway can influence seizures, depression and other disorders. Although the research is thoroughly enlightening, it is still very green. Hang on to your vagus nerve while the research continues.
