What happens when man drinks too much?

When we drink, alcohol goes to our stomach and gets absorbed in the bloodstream. Afterwards, it goes throughout our bodies.

Then the liver breaks it down while producing an enzyme, dehydrogenase, that turns alcohol to acetaldehyde, this is why you get a hangover. Then the acetaldehyde is broken down to acetic acid.

If you kept drinking, you’ll start getting drunk.

Now, after a few glasses you’ll start becoming quite clumsy and maybe light headed. This is when the alcohol starts affecting your brain.

Because alcohol increases GABA (Gamma-Aminobutyric Acid), which is a neurotransmitter that decreases responses, our movement and speech become a bit impaired.

Another thing is that our cerebral cortex is impaired since inhibitory centers there are being reduced at the same time. This is why you’re more likely to be compulsive and do things you wouldn’t even try while sober.

Alcohol also increases the amount of dopamine in the reward center, this is why people who drink alcohol are usually happier.

And alcohol also has an affect on the cerebellum. It’s why we lose our balance and can’t walk straight. And that’s because ethanol stimulates the inhibitory pathways and GABA receptors and eventually suppresses the excitatory pathways as well as NMDA receptors, so that all the functions of the cerebellum are being inhibited.

We know that alcohol stimulates our sex drive because it affect two parts; hypothalamus and pituitary. They both coordinate automatic brain functions and hormone release. Since alcohol depresses the nerve centers in the hypothalamus that controls a person’s sexual arousal… As well as performance. This means higher sexual arousal but lower performance.

Ever wondered why you feel sleepy after drinking a lot? That’s because alcohol, in addition to all those, affect the medulla too. Medulla is the part of the brain that’s responsible for breathing, consciousness as well as body temperature.
