Is the problem of frequent urination at night related to sleep Apnea?

I have sleep Apnea and I got the CPAP machine recently and by the grace of God I am able to sleep well. At night I also get up several times from my sleep i.e., about 6 to 10 to pee. From the day I started using the machine the problem of frequent urination has also disappeared. Is there any co-relation between sleep apea and frequent urination?

The only guess I can make is that when you were having the sleep apnea, you weren't sleeping as deeply, hence your body sensed everytime you had to urinate. Now that you are sleeping more deeply, you are probably just not noticing that you have to go as frequently. Like I said, just a guess.
As a side note: frequent urination at night (nocturia) can be a sign of health problems (diabetes, prostate problems, etc.) so you might want to let your PCP know about this symptom.

Perhaps theat side effect will subside with time. Or you have a chance that diabeties. Any way cunsult dovtor.

NO, there is not. I have severe sleep apnea and frequent urination as well. But there is no relationship between the two. Just a coincidence. If you are sleeping better because of the CPAP machine, perhaps you are also losing weight, or getting into better physical condition because of having higher energy levels. If this is the case, then that would explain why less trips to the potty at nighttime.

Sometimes, During your apnea episodes, your sleep is disrupted or to say, you are "kicked back to a lighter stage of sleep, we would call these episodes arousals'. This may occur many time in a night, during these arousal's other stimuli may then wake you up.. It sounds like your CPAP is working well, Continue to use it.. Best of wishes to you.
