Arthur Krigsman, MD

Gastrointestinal Autism Research Foundation


Arthur Krigsman, MD, is a pediatrician and pediatric gastroenterologist with expertise in the evaluation & treatment of autism associated GI problems. His interest in this unique patient population began in 2001 and during the ensuing 17 years he has treated over 1900 children from across the globe suffering from autism and a variety of GI problems. His research interest lies in the characterization of the unique cellular, molecular & clinical features of ASD-associated IBD and his original findings appear in numerous peer-reviewed journals.

In addition to serving as an invited reviewer for peer-reviewed medical journals, Dr. Krigsman has served as a guest lecturer on the topic of GI disease and autism at national and international scientific meetings, hospital Grand Rounds both here and abroad, Nurse Association meetings, philanthropic organizations, and at numerous lay medical conferences. He has also presented his findings before the U.S. Congress. His greatest satisfaction though derives from the clinical care he provides his patients and in the improved quality of life that results from diagnosing and treating GI disease in this vulnerable population.
