First, let’s clear up a huge misconception: you’re probably not throwing up just water. What looks like clear liquid is often a mix of stomach acid, bile, and saliva that your body is frantically flushing out. Think of it as your internal plumbing’s emergency flush—gross but effective.
So why does this happen specifically after alcohol? Your liver is busy processing the booze, and your stomach gets irritated. That irritation triggers a reflux response, pushing up whatever’s left—usually just water you drank to “stay hydrated” (ironic, right?).
The Real Culprit: Dehydration and Overload
Alcohol is a diuretic, which is a fancy word for “makes you pee like a racehorse.” You’re losing fluids faster than you can replace them. When you finally chug water, your stomach—already inflamed and angry—can’t hold it. Poof, back up it comes.
Another sneaky reason? Vasovagal response. When your blood pressure drops from too much alcohol and not enough hydration, your body decides to empty the stomach to reset itself. It’s like a reboot button, but way messier.
