1
Q

A
missed/delayed meal not enough carbohydrate at last meal increased physical activity too much insulin alcohol (esp. on an empty stomach) tight control (little reserves for unexpected events)
2

how is it managed?
A
concern for T1DM and T2DM treated with insulin
15-20g of rapidly absorbed carbohydrate (glucose tablets or glucose/sugary drink)

A
exercise with low insulin - low glucose absorption into muscle
low muscle glycogen
secretion to glucagon - resulting in excess glucose
