Based on prior study, a significant portion of patients referred for refractory gastroparesis in fact have signs suggestive of vestibular dysfunction as the cause of chronic nausea and vomiting. Our prior retrospective study identified a population of said subjects.
The aim of this study is to further characterize the concomitant symptoms, course of diagnosis, treatment and long-term follow up (up to 5 yrs) of this condition.
