Indiana University Gastrointestinal Motility Diagnosis Registry

June 15, 2026 updated by: John M. Wo, Indiana University

Gastrointestinal Motility Diagnosis Registry

Develop a registry (list of patients) with accurate clinical motility diagnosis. This registry will help the doctors to identify the patients with specific disease conditions. It will also help in promoting future research in gastroenterology motility disorders

Detailed Description

Develop a registry (list of patients) of patients seen the clinics with motility disorders. Motility diagnosis based on billing diagnostic codes are not accurate. Motility diagnosis will be made by physicians with specialized in GI Motility, based on clinical consensus of diagnostic criteria. The information gathered from the database will be used to help promote future clinical research in the GI motility and Neurogastroenterology Unit at Indiana University School of Medicine.

Gastrointestinal motility symptoms are very common. It encompasses a wide range of problems, such as dysphagia, heartburn, nausea, emesis, food regurgitation, abdominal distension, weight loss, postprandial bloating, constipation, and diarrhea. An accurate diagnosis is essential in order to promote cost-effective treatment and future research to benefit patients with GI motility disorders

Specific Aims

  1. Primary Aim: Identification of patients by accurate motility diagnosis

  2. Secondary Aims:

    1. To develop Patient Reported Outcome (PRO) measurements in patients with small intestinal bacterial overgrowth (SIBO)
    2. To develop Patient Reported Outcome (PRO) measurements in patients with gastroparesis
