Yeah, pee. Now for us light-weights, it pretty much happens without any prompting: two pints and I'm racing to the toilet. Then each pint after equals yet another trip. Some would think that was embarrassing, but the Guardian kindly put my mind and weak bladder to rest. You see, binge drinking can lead to...
You think that's funny? Well here's a yummy description:
The mechanics of this gruesome problem are relatively straightforward. Alcohol is diuretic - it makes you urinate more - hence the sight of drunk people urinating in the streets on a Saturday night. Alcohol is also an anaesthetic: it dulls the urge to go. The combination of large volumes of urine, and a dimmed, possibly non-existent urge to pee can result in a seriously over-full bladder.
While most people will just let the urine out one way or another (possibly in their sleep), some will be so "dulled" that they will not feel the urge to "void". If it is not emptied, the bladder will eventually be unable to contain the volume, and - like any over-full bag - can burst apart under the pressure. A minor trauma - say, falling down and bumping your over-full bladder during a drunken binge - can also increase the likelihood of this happening.
According to this article, the 3 to 4 cm rupture is big enough to allow urine poison you from inside.
Makes a person want to jump back on the wagon....ok no it doesn't. Just makes me want to pee.
