Trial Parameters
Brief Summary
The Gastroparesis Registry 4 (GpR4) is an observational study of patients with symptoms of gastroparesis (Gp) and functional dyspepsia (FD) with either delayed or normal gastric emptying. To better understand these disorders, this registry will capture demographic, clinical, physiological, questionnaire, and patient outcome data to characterize the patients and their clinical course. Participants will complete several questionnaires, complete a nutrient drink test and have a gastric emptying study.
