Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Faced with the current obesity epidemic, new avenues of research into effective weight loss must be developed.

Among the possible actions on obesity, vagus nerve stimulation has been shown in several studies to be effective in treating epilepsy or depression, at the same time inducing weight loss in those patients. Vagus nerve stimulation has also shown to be effective on weight loss in experimental animal studies. Vagus nerve stimulation has never been attempted in obese patients awaiting bariatric surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The primary objective is to demonstrate the benefit of transcutaneous vagus nerve stimulation in obese subjects awaiting surgery. Secondary objectives include, among others, the risk factors related to obesity, systemic micro-inflammation, insulin and lipid profile.

Active stimulation

Group Type EXPERIMENTAL

NeuroCoach II Stim

Intervention Type DEVICE

A noninvasive vagus nerve stimulator consists of two components. An electrode is placed in the left ear concha and will be used by the patient for 4-5 hours per day in segments of 1 hour minimum.

For this intervention, the stimulations are active.

Inactive stimulation

Group Type SHAM_COMPARATOR

NeuroCoach II Stim

Intervention Type DEVICE

A noninvasive vagus nerve stimulator consists of two components. An electrode is placed in the left ear concha and will be used by the patient for 4-5 hours per day in segments of 1 hour minimum.

For this intervention, the stimulations are inactive.
