Sleep Apnea and Nocturia

Mechanisms and Clinical Evidence

• Obstructive sleep apnea (OSA) increases arousals and the proportion of light sleep, raising the likelihood of waking, which then leads to urination once awake, according to the European Urology guidelines 1, 2
• When evaluating patients with nocturia, clinicians should consider screening for OSA symptoms using questions about gasping/stopping breathing at night, daytime sleepiness, and non-refreshing sleep, as recommended by the European Urology guidelines 3, 4, 5
• Patients with nocturia who don't respond to conventional treatments should be evaluated for possible undiagnosed OSA, as suggested by the European Urology guidelines 1
