Center for IBS & GI Motility Research

About Our Research Center


The Center for IBS & GI Motility at Beth Israel Deaconess Medical Center is focused on advancing knowledge on the diagnosis and treatment of functional gastrointestinal (FGID) and motility disorders. In addition to conducting evidence-based research studies looking at the biological causes and psychosocial components of FGIDs and motility disorders, the Center is committed to investigating new treatments including pharmacological, complementary/alternative, and lifestyle-based interventions.

Alongside our close collaborations with industry and pharma evaluating new investigational drugs, our Center is leading the way in providing complementary and alternative treatments for FGIDs. Some of our current and past research studies include:

  • Multi-strain probiotics
  • Natural plant supplements for chronic diarrhea
  • Vibrating mechanical capsule for constipation
  • Fecal microbiota transplantation for IBS
  • Different diet strategies for IBS and SIBO
  • Behavioral therapy for insomnia in patients with IBS
  • Open-label placebo treatment
