David Scoular Digestive Disease Center

Digestive diseases represent the most common chronic illnesses in the United States today. Irritable bowel syndrome (IBS) alone affects approximately 20 percent of the population.

To better understand IBS and other gastrointestinal conditions, the David Scoular Digestive Disease Research Center – the research arm of Kelsey-Seybold’s Gastroenterology Department – has joined with other scientists from The University of Texas Health Science Center at Houston and from St. Luke’s Episcopal Hospital in digestive disease research.

Current research projects include:

  • Risk factors and causes of IBS
  • Optimal treatment of IBS
  • Clinical trials for new treatments of chronic liver diseases
  • Use of biomarkers in chronic liver diseases
  • Genetic factors important in the development of digestive diseases
  • Treatment and diagnosis of inflammatory bowel disease (IBD)
