How Antibiotics Influence Blood Sugar in Cystic Fibrosis Patients

Cystic fibrosis (CF) is a lifettening genetic disorder caused by mutations in th CF transmute directance regulator (CFTR) gene.

CFRD is of the mogt comorbidities in cystic fibrosis, affecting up to 50% of adults over age 30 and aproxiately 20% of estacents.

Why Antibiotics Affect Blood Sugar: The Underlying Mechanisms

Antibiotics are not metabolically inert agents. Several classes of austics common used in CF care have been linked to clinically considul ful changes in glukose homeostasis.
