Overview

Brief Summary

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.

Outcomes

Primary Outcomes

Microbiome analysis

Time Frame: 1 year after enrollment

In this study, we anticipate identifying differential functional genomic profiles (metagenomes) and metabolites (metabolomes) between patients with different functional GI disorders, with detailed species-specific reconstruction of microbial metabolic pathways, their complement of gene orthologs, taxonomic distributions, and abundance profiles.

Proteomics

Time Frame: Baseline visit

In this study, we anticipate identifying differential functional genomic profiles (metagenomes) and metabolites (metabolomes) between patients with different functional GI disorders, with detailed species-specific reconstruction of microbial metabolic pathways, their complement of gene orthologs, taxonomic distributions, and abundance profiles.

Whole genome analysis

Time Frame: Baseline visit

In this study, we anticipate identifying differential functional genomic profiles (metagenomes) and metabolites (metabolomes) between patients with different functional GI disorders, with detailed species-specific reconstruction of microbial metabolic pathways, their complement of gene orthologs, taxonomic distributions, and abundance profiles.

Diet and Lifestyle Questionnaire

Time Frame: 1 year after enrollment

This questionnaire evaluates patients' diet, lifestyle, and symptoms relating to their functional GI disorder.

Single Nucleotide Polymorphism (SNP) genotyping

Time Frame: Baseline visit

In this study, we anticipate identifying differential functional genomic profiles (metagenomes) and metabolites (metabolomes) between patients with different functional GI disorders, with detailed species-specific reconstruction of microbial metabolic pathways, their complement of gene orthologs, taxonomic distributions, and abundance profiles.
