What Is a Bolus?
A bolus is an extra dose of insulin, delivered when needed to:
Match the carbohydrates (sugar content) in a meal or snack
also known as a meal bolus
Lower blood glucose when it gets too highalso known as a
correction bolus
This extra dose is in addition to the basal rate delivered through-
out the day and night (see Chapter 3, Understanding and
Adjusting Basal Rates).
The size of a bolus dose depends on the current factors at the
time you deliver the bolus:
Your blood glucose level
Your insulin-to-carbohydrate ratio
Your correction factor
Your target blood glucose and correct above threshold
The amount of insulin on board (IOB) (active insulin) from pre-
vious meal and correction boluses
Your correction threshold, the BG level above which you
would like to take insulin to reduce an elevated blood
glucose
Your activity level
The type and amount of food you eat
