When diagnosing insomnia, doctors look for primary or secondary insomnia. Primary insomnia is insomnia that appears by itself and is not caused by another condition or environmental problem.
Millions of people have secondary insomnia, where inability to sleep is caused by another factor. That can be an underlying condition like anxiety, depression, arthritis, cancer, chronic pain, or heartburn. It could also be a substance: Certain medications, caffeine, or alcohol.
Insomnia sufferers may have problems sleeping most nights or every night. Impairment depends on extent of sleep. Common insomnia symptoms include daytime drowsiness, difficulty concentrating, issues regulating emotion, and memory lapses. Workplace and traffic accidents are also more likely.
Chronic insomnia can eventually cause systemic problems with the body. Sleep removes metabolic waste products from the brain and also plays a role regulating blood pressure. Severe, prolonged insomnia makes a variety of health problems more likely, from weight gain to cancer.
Short-term acute insomnia does not require medical intervention. If someone is experiencing problems sleeping due to environmental factors like noise or light, physical discomfort, or short-term emotional distress, they are usually advised to make changes to the sleep environment.
In chronic insomnia, a sleep study is used. During a sleep study, the insomnia patient spends a night in a specialized sleep lab or sleeps at home while attached to specialized equipment. The equipment records physiological data that can be used to pinpoint the issue.
When insomnia is caused by another health condition, it usually goes away if that condition is under control. Chronic insomnia can be difficult to treat when caused by mental health or circadian rhythm disorder, a problem with the body’s natural sleep-wake cycle. In these cases, sleep-inducing medications are used.

Millions of people experience insomnia, and it is generally understood as a growing problem. Since sleep is tied to all other body functions, insomnia is not just inconvenient: It is a profound quality of life issue. Insomnia clinical trials are key to understanding the most difficult insomnia cases, including those with no obvious cause. With further insomnia clinical research, more effective insomnia treatments can be found.
