Insomnia is a common sleep disorder.
If you have it, you may have trouble falling asleep, staying asleep, or both. As a result, you may get too little sleep or have poor-quality sleep.
You may not feel refreshed when you wake up.
Symptoms of insomnia include:
Lying awake for a long time before you fall asleep
Sleeping for only short periods
Being awake for much of the night
Feeling as if you haven’t slept at all
Waking up too early
Your doctor will diagnose insomnia based on your medical and sleep histories and a physical exam. He or she also may recommend a sleep study.
A sleep study measures how well you sleep and how your body responds to sleep problems. Treatments include lifestyle changes, counseling, and medicines.
