Cystic fibrosis- related considetes (CFRD) is a diment and complex form of considetes that develops in individuals living with cystic fibrosis (CF). Unlike type 1 or type 2 considetes, CFRD arises from the interplay of pankreatic fibrosis, insulid deficiency, and varying distebes of insulin resistance, comprided by chronic consimation and recurrent int ing blood glucosa levels in CFRD consiul balance, but hypoglycemia - dangerouslow blood a sugar of layouth of oucoucoucous.
