Steroids and blood sugar
Steroids (for example dexamethasone, prednisolone) are part of many leukaemia treatments and can raise blood sugar, even in people without diabetes.

01Short answer
02Simple explanation
Tell both doctors. Your haematologist and your diabetes doctor.
Medicine list. Bring it to every visit.
Your own medicines. Do not stop them unless told.
Symptoms. Report changes early.
03Scientific explanation
Steroid hyperglycaemia: sugar rises in the hours after a steroid dose.
End of the course: when steroids are reduced, diabetes medicines must be reduced too, or sugar can fall too low.
04What happens in the body?
Steroids and blood sugar and leukaemia
People with steroids and blood sugar can receive leukaemia treatment; the plan is simply adjusted.
What may change
Treatment and steroids and blood sugar can affect each other, so check-ups may be more frequent.

Two teams together
When your haematologist and diabetes doctor share information, treatment is safer.
