Bolus types


Device: MiniMed 780G insulin pump

A bolus is the amount of insulin taken to cover an expected rise in blood glucose (BG), typically when you eat a meal or snack. You can also use a bolus to correct a high BG reading.

There are different types of bolus deliveries you can use, depending on your insulin needs at the time. There are also different ways you can deliver a bolus. Discuss these options with your healthcare professional to determine what is best for you.

Bolus types

  • Normal bolus: provides a single, immediate dose of insulin. You use this type of bolus to cover your food intake or to correct a high BG.

  • Square Wave™ bolus: delivers a single bolus evenly over an extended period of time from 30 minutes, up to 8 hours. You may use this type of bolus if you have delayed food digestion due to gastroparesis, if you are snacking over an extended period of time, or if a Normal bolus drops your BG too rapidly. This feature is not available in SmartGuard™ technology.

  • Dual Wave™ bolus: delivers a combination of a Normal bolus followed by a Square Wave™ bolus. You might use this type of bolus when you eat meals that are both high in fat and carbs or when your meal bolus is combined with a correction bolus for a high BG. This feature is not available in SmartGuard™ technology.
