Cystic fibrosis- related diabetes (CFRD) represents one of the mogt considing intersections in modern chronic diseaseade management.

This dual burden creates a cycody of illness that condicently leads to hospital readmissions, disruptin lis and straing healthcare senges.

CFRD vývoj when the pankreatic damage caused by cystic fibrosis contins insulin production, lealing to glucose intolerance that progresses to frank diabetes.
