There are several people who love to drink, and even the ones who don't do know at least one such person. And so, it is quite strange that a person has no idea of what occurs to a person who gets drunk. But obtaining such a statement would be quite an exaggeration.
Yes, agreed that many people understand what happens to a drunk person from the outside - how they behave - but how several of us know what precisely happens on the inside? Not many.
The first step of eating/drinking
Anything we consume or drink needs to slip down the food pipe and into the stomach, and the same goes for those alcoholic drinks that get us drunk.
Seeping into the blood
Most of the alcohol get engaged by the food in the stomach, and then digested and absorbed by the walls of the intestine in the form of useful energy. But there is some alcohol that manages to flow into the small intestine without getting absorbed by anything else. The walls of the intestine are very fine and porous, and so the alcohol gets absorbed into the blood stream and is carried around the whole body quite rapidly by the blood.
Which alcohol actually gets us drunk
Not all the alcohol that goes in gets us drunk. It's only the portion of it that gets into our blood and comes back up into our systems that get us going wild.
Where the liver comes into the picture
The liver is the detoxification centre of the body's blood. So it is busy detoxifying the blood that has got alcohol in it.
Here's the twist
The liver tries to break the alcohol down into useful components that the body can use. But in the process, it creates a harmful byproduct called acetaldehyde - and this is what's the real culprit of our worst hangovers.
Why alcohol makes you pee a lot
The next stop for the blood is the kidney, which picks up the leftover alcohol from the detoxed blood. That's why drinking causes you to pee so much.
Felling hydrated? Here's why
The kidney's job is to direct the waste material to the bladder. But because there's harmful alcohol there now, the body needs to excrete it, in other words, the body needs to create an urge to pee. And so, the bladder is hydrated by bringing in water from other parts of the body. This is also why one gets headaches the next morning - it is because of the lack of water in the body that pains the brain.
So that's really how we get drunk
But there's more!
Alcohol messes up the neurotransmitters that run around our brains and direct our conscious and subconscious emotions, actions, and motor skills. That's why a drunk person's speech becomes sluggish, and he loses balance. And that's also what cause the other physical abnormalities that are associated with a drunk person.
The final little piece
Wondering what causes a drunk to lose control over his inhibitions? Well, alcohol affects the hypothalamus and pituitary gland, which are responsible for hormone control. With them down, the hormones go crazy. At the same time, the dopamine released keeps our pleasure centres happy. And that wraps up the entire process that happens within the human body in the presence of alcohol.
