Cystic fibrosis (CF) - related diabetes
Diagnose cystic fibrosis-related diabetes using one of the following:
- continuous glucose monitoring (CGM)
- serial glucose testing over several days
- oral glucose tolerance testing (OGTT) - if OGTT is abnormal perform CGM or serial glucose testing over several days to confirm the diagnosis.
Test for cystic-fibrosis-related diabetes
- in people with cystic fibrosis annually from 10 years of age
- at the end of the first and second trimesters of pregnancy, using CGM or OGTT
- in people with cystic fibrosis who are taking long-term systemic corticosteroids or receiving enteral tube feeding, using CGM or serial glucose monitoring.
Consider testing for cystic-fibrosis-related diabetes in people who still have any of the following despite optimised cystic fibrosis treatment:
- unexplained weight loss
- a deterioration in lung function as measured by spirometry
- increased frequency of pulmonary exacerbations
- excessive tiredness.
