Insulin is a vital hormone used to manage blood sugar levels in people with diabetes. There are different types of insulin, each with specific characteristics. Understanding these types helps in managing diabetes effectively.
Types of Insulin
Insulin types are categorized based on how quickly they start working, when they peak, and how long they last. The main categories include rapid-acting, short-acting, intermediate-acting, and long-acting insulin.
Rapid-Acting Insulin
This insulin begins to work within 15 minutes and peaks around 1 hour. It is typically used just before meals to control post-meal blood sugar spikes.
Short-Acting Insulin
Short-acting insulin starts working within 30 minutes and peaks around 2 to 3 hours. It is often administered 30 minutes before meals.
Intermediate-Acting Insulin
This type begins to work within 2 to 4 hours and lasts about 12 to 18 hours. It is used to provide basal insulin coverage throughout the day and night.
Long-Acting Insulin
Long-acting insulin starts working within 1 hour and can last up to 24 hours. It provides a steady level of insulin and is often used once daily.
