Brief Summary:
The purpose of the DAN-VNS study is to investigate the effects of non-invasive vagal nerve stimulation on gastrointestinal symptoms such as nausea, vomiting, bloating, and diarrhea in people with diabetes.
Detailed Description:
The study is a randomized, double-blinded, sham-controlled, parallel group clinical trial, which will include participants with diabetes and gastrointestinal (GI) problems. These problems may be manifestations of diabetic autonomic neuropathy.
Participants are randomised to received either active non-invasive transcutaneous vagal nerve stimulation (tVNS) or inactive sham stimulation. The study period is divided in two phases. The first phase investigates the effects of short-term, high-intensity tVNS treatment on GI symptoms. The second phase investigates the effects of long-term, middle-intensity tVNS treatment. The primary outcome of both phases is subjective patient evaluation of GI symptoms by the use of validated questionnaires.
A third phase, conducted only on participants, who proved to be responsive to tVNS treatment, will investigate the acute endocrine and metabolic response to short-term tVNS in a randomised cross-over design.
Lastly, healthy volunteers will be included in a cross-sectional, descriptive study in order to provide a comparable baseline dataset.
