Obstructive Sleep Apnea May Increase Nighttime Urination
Researchers find nocturia reduced when CPAP is used
TUESDAY, March 28, 2017 (HealthDay News) -- Treating obstructive sleep apnea with continuous positive airway pressure (CPAP) might help reduce episodes of nocturia, according to a study presented at the annual meeting of the European Association of Urology, held from March 24 to 28 in London.
Sajjad Rahnama'i, M.D., Ph.D., from the Maastricht University Medical Centre in the Netherlands, and colleagues tracked outcomes for 256 patients who were treated for obstructive sleep apnea with CPAP.
Before starting CPAP, 69 percent of the patients had to get up more than once a night to urinate, Rahnama'i's team noted. However, after starting CPAP, nighttime urination was reduced in 65 percent of those patients. For example, 32 of the 77 patients who previously got up twice a night to urinate could go the whole night without doing so after they started on CPAP.
"This is the first study to show the true incidence of nocturia in patients who suffer from obstructive sleep apnea," Rahnama'i said in a news release from the European Association of Urology. "It's also the first study to show the size of the effect of CPAP in patients with obstructive sleep apnea on their nocturia symptoms."
