Clinical Trial Summary

Although obesity is a rapidly increasing epidemic worldwide, it is associated with many health-related comorbidities. As a result of the developments in social life and observes the sedentary life in individuals, an effect of the age of technology the fact that this epidemic will cause even massive health problems in the coming period affecting the health systems of countries and indirectly their economies that, This situation necessitates the creation of alternative treatment methods for the prevention of obesity. This study aims to determine the effect of a therapy approach that can be applied to the vagus nervous system, which is associated with many organs and systems, on weight loss and general health. As an alternative treatment against lifestyle changes such as diet and exercise, individuals have made for weight loss.
