in type 1 low / no c peptide due to absolute insulin deficiency
diagnosing t2DM
asymptomatic but abnormal HBA1c?
repeat then can be confirmed T2dm
monitoring in t1dm?
before each meal and before bed
in pts with t2dm when would you immediately add empagliflozin?
SGLT-2 should be introduced at any point they develop CVD
/ have high risk of CVD

adrenal medulla
releases metanephrine : adrenaline
Investigating adrenal insufficiency?
9am cortisol
100-500
then short synacthen test
cortisol measured

cortisol measured again
cortisol should rise
short Synacthen test
plasma cortisol am measured
Synacthen 250ug IM
check cortisol again (normally should rise in response (>500)
