Sleep Disorders care in Istanbul is available at 4 hospitals in the Voumed network.

Sleep medicine diagnoses and treats the conditions that disturb sleep, restore daytime energy and protect long-term health. By far the most common reason people are seen is obstructive sleep apnea, where breathing repeatedly pauses through the night, but the field also covers insomnia, excessive daytime sleepiness, restless legs and disorders of the body clock. What makes this specialty distinctive is that it is largely diagnostic: the cornerstone is an overnight sleep study that records what the body does while a person sleeps, something that cannot be measured in a normal clinic visit. Patients travel for this care to reach a dedicated sleep laboratory, a coordinated team across several specialties and a clear plan, often combining the assessment with a calm, restful stay. Treating poor sleep is not a luxury, because untreated sleep disorders quietly raise the risk of accidents, high blood pressure and heart problems.
