A study has found that reducing obstructive sleep apnea (OSA) can reduce the need to get up and urinate at night (nocturia). This study confirms the link between apnea and nocturia, and supports the idea that lifestyle management may contribute to reducing nocturia in certain cases.
New Dutch research, presented at the European Association of Urology (EAU) conference in London, shows that using CPAP also reduces the frequency of nighttime urination.
Sajjad Rahnama’i, MD, PhD, from the Maastricht university Medical Centre (the Netherlands) studied 256 patients (206 male, 50 female) who were treated for OSA by a CPAP. Prior to treatment for apnea, 69% of these patients reported nocturia (the need to get up and urinate more than once a night). After starting to use CPAP, nearly 2/3 of patients (65%) reported a reduction in the need to urinate at night. The exact figure depended on the severity of the nocturia, with for example 32 of the 77 patients who previously reported 2 episodes per night, were able to pass the whole night undisturbed while using CPAP.
Rahnama’i says in a release, This is the first study to show the true incidence of nocturia—peeing at night—in patients who suffer from obstructive sleep apnea. It’s also the first study to show the size of the effect of positive pressure mask treatment (CPAP) in patients with obstructive sleep apnea (OSAS) on their nocturia symptoms ”.
Commenting for the EAU, Marcus Drake (Bristol, UK) says, “It may seem surprising that breathing problems can cause excessive urine production while asleep, but actually the problem is very real. To have a study showing the link, and the potential benefits of therapy, may help establish the treatment into routine clinical practice”.
Hi, I have been on CPAP for nearly 2 months. Prior to this I woke up to wee quite a few times during the night; sometimes 4 times a night. I, therefore, agree with this study. The downside is that I have started to put on weight. I still have the same amount of exercise and diet but am gaining weight. Could a study been done on weight gain during CPAP perhaps?
Interesting about the weight gain. I have nocturia and am about to start CPAP therapy. I’ll comment back later with my thoughts and if I experience weight gain.
In response to the weight gain, the opposite was true for me. After I started CPAP therapy, I had more energy and started becoming more active. I kid you not, without changing my diet I lost approximately 100 lbs. in the first year. Being tired is depressing and would keep anyone from living a quality lifestyle.
