I don't understand the relationship: How does CPAP decrease urinary frequency?
I think the many apnea events were triggering the body to “wake up.”
Once awake, any feeling of the need to urinate was registering in the brain, so, off to the bathroom (repeated however many times nightly). Logical to think that waking up was the result of needing to urinate (and not from apnea events).
With CPAP, the person sleeps through soundly (few apnea events) and NOT waking up frequently. Normal bathroom trip in the morning after waking and getting up for the day.
That’s been my experience.
The simple version I got:
Your body is doing it’s best to *wake you up.* It’s one of the body’s ways of pulling out all the stops to get you awake enough to breathe again. It sounded silly to me at the time...
That said, the CPAP has truly been a blessing.
Some nights after exercising too closely to bedtime and not cooling down with stretches, I will fall asleep without my CPAP. I will wake thinking I will never make it to the bathroom. At least I know why, now, and don’t panic.
Also, headaches. I would wake up with headaches SO bad I would be like a little puppy and whine. As long as I’m using the CPAP those have gone down to almost nothing.
Folks using CPAP can really feel the difference if they have to go without their CPAP for a day or two.
