Sleep Apnea and Nighttime Urination

A recent study evaluated nocturia as a predictor of obstructive sleep apnea (OSA). Nocturia involves excessive urination at night. It can cause a person to wake up several times during the night to urinate.

Nocturia is a known symptom of sleep apnea. This study examined it as a potential screening tool. Snoring is already a common screening tool for OSA.

The study was published online by the journal Sleep and Breathing in October, 2009.

It involved more than one thousand adults who had sought help at a sleep disorders center. They were all older than 18 years of age.

Each person completed medical and sleep history questionnaires. They also took an overnight sleep study. Of the participants, 797 had sleep apnea, 777 reported snoring, and 839 reported nocturia.

Results show that self-reported nocturia can effectively predict OSA.

The researchers suggest that nocturia may be a useful screening tool for sleep apnea.

Research also shows that CPAP therapy for sleep apnea reduces awakenings to urinate.

Sleep and Breathing is the official journal of the American Academy of Dental Sleep Medicine.
