An overreactive vagus nerve can lead to fainting spells, according to DrSircus.com. On the other hand, an underreactive or inert vagus nerve is a common cause of gastroparesis, a typical complication of diabetes. Some of the symptoms associated with gastroparesis include nausea, stomach spasms, stomach pain and weight loss.

Pressure on the vagus nerve can also lead to unconsciousness and a clammy skin, HealthGuidance.
