Intestinal Permeability and Gastroparesis


About this study

The purpose of this study is to investigate, using several novel techniques, potential pathophysiologic abnormalities that could lead to the development of symptoms of gastroparesis (GP).  The global hypothesis is that patients with GP will be more likely than controls to have abnormalities in duodenal intestinal permeability.
