Not needing to urinate (pee) at night.

[DariaVader]

This link on the Respironics blog gives a general explanation: The Link Between Bathroom Trips and Sleep Apnea

I'm still not sure I fully understand the reason. It has to do with obstructed breathing, lower-than-normal pressure in the chest cavity, and increased secretion by heart muscle of a hormone called ANP (Atrial natriuretic peptide).

So when you start CPAP treatment, ANP levels apparently go back to normal.

ANP isn't the only factor that can cause nocturia, according to Wikipedia. It just seems to be the one most often associated with sleep apnea.

I find all this fluid balance stuff to be hugely complex.

Yes - this.

ANP is a diuretic hormone that your atria secretes in response to the apnea incidents.

I have never in all my life slept thru the night without peeing until I began therapy. It's one of my evidences that apnbea has been with me for a long time.

I responded to this thread previously with a "yes I too stopped needing to get up during the night to pee". This recent discussion has caught my attention because I have Central Apnea. I didn't have negative pressures in my chest when trying to breathe because I wasn't trying to breathe. I did have O2 desaturations. The desaturations might have more to do with nocturia. Just a thought.

Based on the advice of this forum, i have decided to up the starting pressure of the machine. I up my pressure every few days. I am now up to 8cm and will increase it again to 8.5cm. The past few weeks I have found I do not need to get up to urinate, I sleep right through the night. Slept a full 8 hours last night with no interruption. I haven't done that for years.

Pleasantly surprised, I had a CPAP but without apneaboard, I would not have gotten here!

I up my machine when my sleephead reports an AHI over 5cm. I heard in here I could probably go up to 11, but I will see. Upping the starting pressure has made all the difference.

Hi WTF. Do you have an auto-adjusting machine that you're using in fixed pressure mode? Just curious.

No, it's in APAP mode. I'm just adjusting the minimum pressure upwards.

So your treatment pressure is 8.0-15.0 cm?

Do you know what 90% (or 95%) pressure and median pressure your machine (or SleepyHead) reports?

No, it's in APAP mode. I'm just adjusting the minimum pressure upwards.

Guess I'm just lucky, usually have to go a couple times a night. A rare night when I sleep straight through.

My 90% pressure for June is 13 cm H2O according to SH.

I know the chances of this happening to any other person on this board is zilch, but realize that there is more than one cause of needing to pee at night repeatedly. I kept putting it down to not getting enough sleep (RLS), taking my mask off at night and not putting it back on, as well as disruptions from firecrackers and thunderstorms. That was until I tested myself one morning and GACK, my blood glucose was over 300! It seems that I no longer produce insulin (not type 2, but LADA) and so the constantly getting up to pee was all the sugar in my blood. The sad part is that I did test on a daily basis, but just one time a day as per doctor orders and apparently kept missing the very high numbers. I should have been more suspicious since I do eat a lower carb diet. Now that I test 8 times a day, I can see how I kept missing the obvious.
