The Bean never falls far from the stalk
Just a little formulating to do this morning to try and predict Sarah's BG levels.
With a 1:12 Carb/Insulin Ratio
50 (1 unit drops bg by 50mg) divided by 12(ratio) = raise bg by 4 mg per carb
so we conclude 1 carb raises bg by 4 mg or points
With a 1:10 Carb/Insulin Ratio
50 divided by 10= raise bg by 5 mg per carb
so we conclude 1 carb raises bg by 5 mg or points
Sarah had 14 carbs for breakfast
She was on a 1:10 ratio
50 divided by 10 = 5 mg per carb 14x5= raise blood by 70 mg
Morning BS was 149 149+70= raises her bg to 219 without any insulin
She took 1.5 units of insulin which will drop her 75mg in four hours which should put her at
2.5 hours after her breakfast bg was 157.
219-157= bg dropped 62 mg in 2.5 hours. Still having (.5 of her insulin left) it will drop her another 25mg in the next two hours.
157-25= 132 4 hours after breakfast
She had 5 carb snack at 2 hour check.
5x4= 20 uncovered carbs
132+20 = Now bg will be 152 four hours after breakfast. ****In theory
Do you think that the formula actually worked? No
Four hours after her morning insulin and breakfast, she was 105.
No amount of formulating can predict what a person's bg will do.
