Here's a not too surprising study presented at the American Urological Association meeting: That two or more bathroom trips at night increases your chances of dying by 50% in men and 30% in women. The researchers mentioned poor sleep as a possible link, but didn't mention anything about obstructive sleep apnea. Studies have recently shown that the main reason why you get up to go to the bathroom is because you stopped breathing, and not because you make too much urine. Actually, you do make some more urine, due to increased production of atrial natriuretic hormone (ANH), due to dilation of the heart's atria during breathing pauses.
The surprising finding in this study was that even in young men (20 to 49), two or more trips to the bathroom more than doubled the risk of death. This is also the age then obstructive sleep apnea begins to take hold.
Knowing what we know, I believe that anyone who has to go to the bathroom too often at night, or even those that have to go often during the day should at least be screened for undiagnosed obstructive sleep apnea. What do you think?
