Types of Insomnia

Insomnia is a condition that comes in several forms. Your healthcare provider will determine which insomnia type you have based on what is causing it, how often it occurs, and how long it tends to last. For example, your insomnia could be classified as primary or secondary. Insomnia can also be categorized in other ways, such as whether it is acute, transient, or chronic.
