New ways to diagnose bile acid diarrhea with Dr Robert Battat

Bile acid diarrhea is a common cause of diarrhea in patients with IBS and IBD. Currently, our diagnostic tools are unaccessible and often, therapeutic trials with bile acid sequestrants are used in the diagnosis. Dr Robert Battat shares his research with a new diagnostic marker, C4, in the diagnosis and management of B.A.D., leading to more targeted care for patients.

Robert J. Battat, M.D. is an expert in inflammatory bowel disease specializing in Crohn's Disease and Ulcerative Colitis. He is an Assistant Attending Physician at the New York-Presbyterian Hospital/Weill Cornell Medicine and the Jill Roberts Center for Inflammatory Bowel Disease.

Dr. Battat obtained his medical degree and completed both his internal medicine residency training and clinical gastroenterology fellowship at McGill University in Montreal, Canada. He subsequently completed a clinical and research fellowship in inflammatory bowel disease at the University of California, San Diego and at Robarts Clinical Trials under Dr. William Sandborn and Dr. Brian Feagan.

He has a major interest in personalized medicine in inflammatory bowel disease and has extensively published scientific articles on this topic. This includes the development of a serum tess to diagnose bile acid malabsorption -which leads well into our topic today!

Dr Battat and I discuss:

• What is bile acid diarrhea?
• How does bile acid diarrhea develop?
• How is it diagnosed?
• • SEHCAT Test
  • Therapeutic trial
  • C4 Testing as a measurement for precursor to bile acids
• Is it a common cause of unexplained diarrhea in your practice?
• How is BAD managed?
• Do you often see an overlap between BAD and IBS? IBD & BAD?
• Where the research is going with BAD diagnosis and management and what can patients and health care providers expect?
