Functional GI Disease Registry

The goal of this study is to establish a prospective observational cohort of individuals with functional GI disorders (functional constipation, irritable bowel syndrome, chronic nausea, functional diarrhea, and functional dyspepsia, as well as a subset of these individuals starting neuromodulation for their functional GI disorder) and collect clinical information and specimens. This information will be used in order to establish a patient registry with detailed clinical data and a specimen repository for future research as well as to specifically identify environmental, genetic, physiological, and psycho-social factors associated with functional GI disorders.
