Stefano Guandalini, MD, is an internationally recognized expert on celiac disease, a digestive disease that damages the small intestine and interferes with absorption of nutrients from food. He is also known for his expertise in the research and treatment of other diarrheal diseases in children.

Dr. Guandalini's clinical and research efforts have greatly influenced the way celiac disease is diagnosed and treated today. His work contributed to the revision of 20-year-old guidelines for celiac disease diagnosis.

Dr. Guandalini created the University of Chicago Celiac Disease Center in response to the low rate of celiac disease detection in the United States. This innovative program is dedicated to patient care services, research, medical education and public awareness initiatives in order to increase the rate of celiac diagnoses and improve the lives of celiac patients. The Celiac Disease Center serves patients of all ages.
