1.Insulin sensitivity is the amount (in mg/dL or mmol/L) by which blood glucose will be lowered after taking 1 unit of insulin.

Consult with your healthcare professional to determine your insulin sensitivity.

Choose a meal you might eat and fill in the blanks.

Food: ________ grams of carbohydrate: ______________

________ grams of carbohydrate: ______________

total grams of carbohydrate: ________________

Your insulin to carbohydrate ratio: 1 unit of insulin for _______ grams carbohydrate.

Divide your total carbohydrates by your insulin to carbohydrate ratio and take _____units of insulin

for your meal.

Meal bolus, correction bolus and insulin sensitivity

Jason is ready to eat his breakfast. He has calculated that he will need 4.0 units for his food.

He tests his blood glucose and finds that it is 200 mg/dL (11.1 mmol/L). Jason knows that his blood

glucose level is above his blood glucose target and will need additional insulin before he eats.

Jason's healthcare professional has determined the following for him:

Target BG: 110 mg/dL (6.1 mmol/L)

Insulin sensitivity:

36 mg/dL (2.0 mmol/L)

Jason determines that he will need a correction bolus of 2.5 units insulin to lower his elevated blood

glucose. The 2.5 correction bolus will lower his current BG of 200 mg/dL (11.1 mmol/L) to his target of

110 mg/dL (6.1 mmol/L).

Elevated blood glucose: 200 - 110 = 90 mg/dL (11.1 - 6.1 = 5 mmol/L)

Correction bolus: 90 / 36 (insulin sensitivity) = 2.5 units

(He will add this 2.5 correction bolus to the 4.0 units of insulin that he will need for his meal bolus.

Jason will take a total bolus of 6.5 units.)
