Rochester, Minnesota




G. Richard Locke III, M.D., applies epidemiologic and outcomes research techniques to questions regarding gastroesophageal reflux disease (GERD) and functional gastrointestinal disorders. GERD, irritable bowel syndrome (IBS), constipation and dyspepsia are all quite common problems in society.

Focus areas

  • Epidemiology and outcomes research in gastroenterology
  • Functional bowel disease (epidemiology and clinical)
  • GERD (epidemiology and clinical)
  • Gastrointestinal motility (clinical)
  • Esophageal adenocarcinoma (epidemiology and clinical)

In the course of his research, Dr. Locke uses a bowel disease questionnaire and a gastroesophageal reflux questionnaire.

Significance to patient care

Dr. Locke studies why people develop these problems, why people seek care, and what processes of care provide the best outcomes. The focus is on the patient. Dr. Locke's research has identified that these problems run in families. Current work is trying to separate how much of this is nature versus nurture.
