World Crohn's and Colitis Day is observed annually on May 23 to raise awareness about Crohn's disease and ulcerative colitis, the two most common types of inflammatory bowel disease (I.B.D.). Approximately 7 million people worldwide are affected by I.B.D., which is a serious and chronic digestive condition with no known cure or recognized cause. The day aims to highlight the struggles faced by patients and increase public understanding of the pain and suffering associated with these diseases. Observers may engage in educational activities and initiatives to promote awareness and support for those impacted by I.B.D. The observance reflects a growing recognition of the condition, which has seen an increase in diagnoses over the past two decades.
