Unconsciousness?

Issue
Iv asked many Drs including anethetists,Why do patients no matter what the cause who have been Ko,d tend to vomit on recovery and no one has been able to give a satisfactory answer.

Best Tip

If the person has a Concussion they may vomit.

If an athlete has a concussion, according to the Centers for Disease Control and Prevention, coaches, parents, or other students might notice that the injured player:
Appears dazed or stunned
Is confused about assignment
Forgets plays
Is unsure of game, score, or opponent
Moves clumsily
Tips questions slowly
Loses consciousness
Shows behavior or personality changes
Can't recall events prior to hit
Can't recall events after hit
Or the athlete himself might report the following symptoms if he has a concussion, including a:
Headache
Nausea
Balance problems or dizziness
Double or fuzzy vision
Sensitivity to light or noise
Feeling sluggish
Feeling foggy or groggy
Concentration or memory problems
Confusion

Others
You've asked Drs, medical experts (supposedly) and didn't like their answers so you're asking a bunch of muppets on the internet to come up with something better?!

Good Luck!!!
I assume it could be because they swallowd air.
b/c they ate/drank b/f being put under
Vomiting is a reflex in manyu situations- shock, seizures, food poisoning, etc. It may be part of the 'fight or flight' reaction to pain or illness we have.

Many animals vomit when ill, stressed, threatened, handled, captured, etc. I suspect it is a combination of things:
- get rid of stuff that the body is using energy on so the body can do other things instead
- 'jettison ballast'- lighten up the body for other responses
- scare off or disgust an attacker

The instinct seems to be ancient if we share it with so many other animals. Old instincts often become confusing to understand when they are triggered by new behaviors, like coming out of anethesia, etc.
Some people have a reaction like that to the anesthesia and they throw up after the surgery. If one knows that they are prone to that, they can have a dose of anti-nausea meds to counter act the effects of the anesthesia.
generally if you've been knocked in the head your going to have a headache. when you have a headache it is easier to become nauseated. when you are nauseated you often vomit
