Just wanted to say that I am very happy and so relieved to have this machine.
I hadn't realised how I must have been panicking as I drifted into sleep.
I am also thinking I have have had SA for years, way before PMR.
My main reason for this update is to share this. Before the CPAP machine I could be up for the loo x5 per night...have been this way for a long time.
Now.....I don't get up for the loo! What intrigued me and made me search was that when I did go to the loo, there was always plenty of urine....so how come I now am not making so much.
"Nocturia, or nocturnal urination, is sometimes a symptom of sleep apnea. In fact, nocturia among younger individuals--who are less likely to have other medical causes of nocturia--is a strong indicator of sleep apnea. While the precise relationship has not been thoroughly studied, it appears that the most likely reason patients with untreated sleep apnea have more frequent urination at night is related to the increased pressure in the right side of the heart. This increased pressure is usually the result of low oxygen levels in the bloodstream caused by the apnea events: when oxygen levels fall, the heart works harder to get oxygen to the brain.
An increased pressure in the heart is a sign that there is too much liquid in the body: when the heart receives the stimulus of the increased pressure, higher levels of a hormone called atrial natriuretic peptide (ANP) are secreted. ANP is a diuretic that is associated with the increased need to urinate.
When sleep apnea is effectively treated, nighttime urination is also reduced. Studies have shown that ANP levels in patients with untreated sleep apnea are increased and levels reduced in patients using CPAP effectively. Remember, not all causes of frequent urination are related to untreated sleep apnea; prostrate problems, for example, may cause increased need for urination. Discuss any concerns you may have with your doctor. "
