a personal question..

Yes JohnBFisher LOL, I guess I listened well to my mother and King George V.

I never had the problem with night time urination, but I am still battling restless leg syndrome. My sleep tech told me that they were going to take a detailed look into my study to confirm it, but that was the last I heard of it... I'm on my feet all day now, and my legs never feel rested after a night's sleep (even before baby boy arrived.)

It's been 2 months, and no more waking up to go to to the bathroom for him! He also said that my first night on CPAP was the best night of sleep HE had in a long time!

Makes sense to me! Anything that keeps you from sleeping well (not just apnea) will make you have to pee at night. If he wasn't sleeping because you weren't sleeping, that would cause increased urination also.

Before starting to use CPAP I would have to have to go to the bathroom at about 4am every night, it was that regular and I had a VERY full bladder.

The first night I used CPAP I didn't have to go during the night and haven't had to go since at night. The change was that sudden.

As an interesting aside, my doctors were pretty sure that my nightime full bladder was directly due to diabetes.......I think as more and more doctors become aware of the effects of OSA the more people can be helped (saved!!). To that end, I am going to be writing to mt previous doctor and telling him what the cause of my nightime peeing was (along with nightsweats, morning migraines, depresson, very high BP, etc) so that it might help him diagnose soemone one day.

I used to have the same issues but no longer! I now urinate at approximately 7 a.m. daily. Problem is I don't get out of bed until 8:00 a.m.



Seriously though... I do find the very same thing happening and have no idea as to why. It is a good question for my next visit to the GP unless the answer is posted here. Going to take a look through all the posts. No night sweats, no sky high BP, pulse is down to about 60 or so at night and Sp02 running over 90% while at rest/asleep. Lung capacity at 70% right now and improving with physio. Gotta keep the BP down folks. It kills silently.

Agreed!!

I was on BP drugs for about 3 or 4 months with absolutely no effect on my high BP and they were left scracthing their heads. After 2 weeks on CPAP my BP on average was down 15%, so almost overnigh.

I'm hoping for more falls in my (high) BP as time goes on. The point is though - now I have some hope, at least now I know what's causimng it .

It's possible both were true. Higher blood glucose seems to increase apneas. Oh, and higher number of apneas seems to increase blood glucose levels. Talk about a vicious cycle!

You need to get BOTH under control. If you blood glucose is poorly controlled, so will be the sleep apnea. Likewise, if the sleep apnea is poorly controlled, it will be difficult to poperly control the blood glucose levels.

Here are some studies on point:

Type 2 Diabetes, Glycemic Control, and Continuous Positive Airway Pressure in Obstructive Sleep Apnea
http://www.myresmed.com/Shared/StaticFi ... AP_OSA.pdf

It concludes:

These findings suggest that SDB is pathophysiologically related to impaired glucose homeostasis, and that CPAP can be an important therapeutic approach for diabetic patients with SDB.

Treatment with Continuous Positive Airway Pressure May Affect Blood Glucose Levels in Nondiabetic Patients with Obstructive Sleep Apnea Syndrome
http://www.journalsleep.org/Articles/280507.pdf

It concludes:

CPAP treatment in nondiabetic obese patients with OSAS may have an immediate elevating effect on blood glucose.

By the way, in my mind, this paper indicates just how interlinked sleep is with blood glucose control. You would think that CPAP would improve blood glucose, but in fact it can increase glucose resistance!

Sleep Apnea and Daytime Sleepiness and Fatigue: Relation to Visceral Obesity, Insulin Resistance, and Hypercytokinemia
http://jcem.endojournals.org/cgi/reprint/85/3/1151

It concludes:

We conclude that there is a strong independent association among sleep apnea, visceral obesity, insulin resistance and hypercytokinemia, which may contribute to the pathological manifestations and somatic sequelae of this condition.

Thanks so much for posting those links, I'll have a good read of them later

I have no doubt that there is a correaltion between OSA and blood sugar. In my case, my nightime full bladder was placed firmly at the door of diabetes with OSA not considered at all. The night I started CPAP my nightime peeing completely stopped.

Interestingly - I was diagnosed witn Type II diabetes about a year before starting CPAP. Did my OSA cause my diabees? Possibly or had a big part in it (although I believe I have had OSA my entire adult life).

Also interestingly - since starting CPAP my HbA1C levels have increased - although I have put on weight in the last 3 months and my diet has slipped somewhat. So it will be interesting to see if, with weight reduction and diet improvement, what my HbA1c levels look like against a backdrop of continued CPAP therapy.

What an unfortunate side effect of CPAP if it is the case that it can increase blood sugar levels!!! Still, weighed against all the benefits of CPAP it's more than worth while and at least I can attack blood sugar levels in other ways.

Exactly. I think less movement during the night due to better sleep allows the blood glucose levels to climb. So, we should not use this as an excuse to avoid xPAP therapy (we should follow your example). Rather we need to be aware of the possibility of an increase with CPAP and manage blood glucose levels.

However, I find that my overall blood glucose control is MUCH better with better xPAP therapy. I eat less. I exercise more. It stays in better control.

Yes exactly. Since I have started CPAP yet another thing that has changed is my craving for carbs and sugar first thing in the morning and throughout the day, especially the afternoon.

So, like yourself, continuing CPAP will help me lose weight because I am not literally addicted to junk food. I don't comfort eat anymore because I am depressed. I can see a way out (finally!!!) and will be able to break the vicious cycle of

bad health
bad sleep
bad food
bad health....
