Brazil sees rise in inflammatory bowel disease prevalence

Data from Brazil’s Unified Health System (SUS) indicates a significant rise in the prevalence of Inflammatory Bowel Diseases (IBD), including Crohn’s disease and ulcerative colitis. Between 2012 and 2025, estimated prevalence rose from approximately 30 to 158 cases per 100,000 inhabitants. Researchers identified over 337,000 individuals with these conditions, including 207,000 with ulcerative colitis and 99,000 with Crohn’s disease. Projections suggest prevalence could reach 264 cases per 100,000 inhabitants by 2035 if current trends continue.

Experts note that this increase may reflect improved identification and better clinical tracking rather than just a rise in new cases. This growing data highlights an increasing demand for diagnostic exams, continuous treatment, and specialized medical teams.

In response to these health challenges, the organization DII Brasil is celebrating 10 years of advocacy. The group focuses on improving public policies and clinical support for IBD patients. A major milestone includes the enactment of Law No. 15.138/2025, which provides institutional recognition for demands regarding early diagnosis and assistance measures.
