The Purpose of Puke

Your body has evolved to protect you.

One protective mechanism protects you from toxic things you might ingest.

Potential Causes of Nausea and Vomiting

Verywell / Cindy Chung

When you eat something toxic, several triggers give you nausea (theurge to vomit.)

Taste and smell are two of the most powerful.

If it smells or tastes nasty, your body may reject it as dangerous.

Seeing, smelling, or hearing someone else vomit can make you vomit, too.

But what if nobody else got sick or if youre all alone?

You could still have eaten something bad for you.

Well, its the brain.

Your brain works in a very narrow range of happiness.

If it gets too much sugar, it doesnt work right.

If it doesnt get enough sugar, it doesnt work right.

Its too finicky to dine on fat and it needs a certain amount of oxygen.

It cant be too warm or too cold and it cant be under too much pressure or too little.

Basically, brains are high maintenance.

Its an unintended result of the body thinking any problem with the brain is due to something you ate.

Are you on a boat?

If not, then look for some additional telltale symptoms.

Other times its just the bodys protective instinct at work.
