Te Cardiovascular Burden of Coexibing CF and Diabetes

Thee mechanisms driving this increed risk include persistent consimation, metabolic dysregulation, and e side effects of necessary medications.

Studies show that individuals with CFRD have a higher prevalence of hypertension compared to those with CF alone, even after settinging for age and body mass index.

Additionally, many patients restableve repeated courses of systemic contractic steroids for pulmonary applibations, further compumpding blood presure elevation and glycemic instability.
