I better write it down. It can always be used as a reminder.
Just a clarification, LOW blood glucose is not only when we get the dreaded reading of LO(W) on the meter, but any reading which is below our desired set range.
TESTING FOOD last bolus (insulin dose) for food was too much INSULIN insulin worked faster / more potently than usual AFTER HYPO felt / tested low and have treated it with fast acting sugary food AFTER HYPER no other food taken, no bolus other then correction given AT ANY OTHER TIME, 4 hours or more after last bolus, including during the night | 1- hands not dried properly – tested the residue of water mixed with blood (diluted blood) instead of the blood itself 1A- not enough blood in the testing strip (some blood glucose meters will give an error, others will wait until there is enough blood in the testing strip, but some just might do the test with the incomplete sample giving you the false low (comment added July 2014) IN any case - if suspicious RE-TEST ! 2- did not count carbs correctly so ate less carbs then counted / guessed and bolused for too much 3- insulin to carbs ratio needs revising (I:C) 4- ate fatty or high protein meal, or very low GI meal (these take a long time to digest and insulin may act before the food gets digested causing hypo first and hyper later) 5- injected into muscle 6- injected straight into vein 7- physically very active after bolus 8- under-treated the hypo; not enough carbs to get the BG back up and to make it stay up 9- insulin sensitivity factor (ISF), known as correction factor needs revising 10- basal insulin is possibly too strong / too much for that part of the day / night, basal rate needs revising |
