Just a Mathematician



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 


Today
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 
219-75= 144. 


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.

  1. I literally got lost on the first line. This is pure craziness! You don't need a calculator, you need a crystal ball.

  2. You had me at formulating. I'm with Greg, that's more math than I have done since high school.
