How Insomnia Is Diagnosed

There is no single standard test for insomnia. Diagnosis typically involves a comprehensive evaluation by a healthcare professional:

1. Physical Examination: A detailed assessment of signs and symptoms, along with screening for medical conditions like diabetes or thyroid disorders.
2. Blood and Lab Tests: Tests to rule out other conditions affecting sleep, including electrolyte imbalances and other biomarkers.
3. Sleep Studies (Polysomnography): Optional studies to rule out conditions like sleep apnea, night terrors, or periodic limb movements.
4. Review of Sleep Habits: Self-reported questionnaires assessing sleep patterns, daytime sleepiness, and total sleep time.
