Why does alcohol make you piss so much/ so fast after drinking it?


Why does alcohol make you piss so much/ so fast after drinking it?

In: Biology

My guess is it either makes you thirsty or something in the booze makes you need to pee (like caffiene in soda)

I can’t give a real scientific reason because I’m dumb af but I do believe it’s because alcohol is a poison and when your kidneys filter your bloodstream the majority of the alcoholic drink immediately gets filtered for expulsion through urination because your body is trying to get rid of the toxins as soon as possible. It’s definitely not because it boosts your digestive system like caffeine

It’s because your liver is working overtime to flush out all the alcohol, which is a toxin. So when your body recognizes this sudden uptake of toxic liquids, you start to process and expel them at an accelerated rate.

It’s to do with a hormone called the anti diuretic hormone (ADH). ADH gets released and tells your kidneys to reabsorb water. Alcohol suppresses ADH causing your kidney to retain more water, thus making you pee more.

Your body wants to flush alcohol out of your system before it poisons and kills you. It is a diuretic, which means it makes you pee more.

That said, a lot of times that effect is overblown. You might head out for a beer after work, drink it, then nature calls and you’re off to the loo and you think ‘ha ha broken the seal’.

Actually, you weren’t particularly thirsty before leaving work and hadn’t been to the toilet in a few hours. Drinking a couple of pints of anything at that point would have made you need to wee. You need to drink more than a couple of pints of beer before the alcohol content is the leading cause of urination, and not the fact that you’re drinking large amounts of water when you’re not thirsty.
