What this Trial Is About

The purpose of this study is to find out if investigators can stimulate the vagus nerve (a nerve in the body that runs from your brain to the large intestine), and influence insulin, C-peptide, and glucose levels. C-peptide is a substance that is created when insulin is produced and released into the body. The vagus nerve is a largely internal nerve that controls many bodily functions, including stomach function. Investigators hope that by stimulating the vagal nerve using the TeNS behind the ear, this stimulation can affect insulin levels, and this will help innovate treatment of patients with nausea, vomiting, and disordered stomach function, and patients with diabetes. Researchers hope to be able to measure the activity of the vagus nerve when it is stimulated in other ways. This could help investigators learn more about studying this nerve in the future.
