CF-related diabetes (CFRD) is the most common comorbidity in CF and occurs in up to 25 percent of adolescents and 50 percent of adults living with CF. CFRD has a negative effect on lung function, nutrition, and survival. As early CFRD may be clinically silent, the CF Foundation recommends screening for CFRD beginning by 10 years of age. A diagnosis of CFRD is typically made based on standard American Diabetes Association criteria (e.g. fasting blood sugar > 125 mg/dl (7.0 mmol/L) and/or a 2-hour OGTT blood sugar ≥ 200 mg/dl (11.1 mmol/L))
