Brazil sees fivefold increase in inflammatory bowel disease cases
A study presented at the 74th Brazilian Congress of Coloproctology reveals a significant rise in inflammatory bowel diseases (IBD) in Brazil. Between 2012 and 2025, the incidence of conditions such as Crohn's disease and ulcerative colitis increased fivefold, rising from 30 to 158 cases per 100,000 inhabitants.
Researchers Abel Quaresma and Paulo Kotze, representing the Brazilian Society of Coloproctology, utilized data from the Unified Health System (SUS) to conduct the study. They noted that the annual rate of new diagnoses also climbed from 9.35 to 12.34 per 100,000 inhabitants during this period.
Experts suggest the rise is multifactorial, involving genetic predispositions and environmental factors. Specifically, the consumption of ultra-processed foods containing additives like preservatives and dyes is being investigated as a potential catalyst. Projections suggest incidence could reach 22.7 per 100,000 inhabitants by 2035, potentially creating a major public health challenge due to the high cost of long-term treatment.
