What type of insulin will peak within 2-4 hours?

The type of insulin that typically peaks within 2-4 hours is known as short-acting insulin. Examples of this category include regular insulin, which is often used to manage blood glucose levels during meals. This insulin works quickly to lower blood sugar but has a shorter duration compared to longer-acting insulins. It is important for individuals using short-acting insulin to monitor their blood sugar levels to avoid hypoglycemia during its peak action time.
