why does sticking your finger down your throat makes you want to throw up?

It's called a gag reflex.  It's a defense mechanism the body has to keep us from chocking on things.  If I remember right there are 3 spots that will set off the gag reflex;  I just do not know for sure where they are all located.

I think I know what you're talking about.  After I eat too much or something, I just have to...let some of it out.  Not because I want to control my weight, but because throwing up some of it helps make my stomach less stuffed.  Instant gratification, you know?  I don't even really have to try.  I just involuntarily gag a few times (over the toilet, if you please), and voila.  If you NEED to throw up, you're body will do it for you without much coercion.\n\nBut you really shouldn't make this a habit - as you know, it's not good for you, and it's best to investigate the reasons why your stomach is always upset.

The frequency of the sound stimulates the nervous system causing an involuntary muscular reaction at the base of the neck. This has the effect of causing you to shudder; making your spine tingle; putting your teeth on edge, or a combination of all three.

rabies virus cause severe pharyngeal muscle spasms, when a person tries to drink water or other liquids, which leads a forcible vomiting which causes severe pain to throat. this on repetition, person fears of the pain caused by the spasms and vomitings, when he thinks about water..........

Not only is throwing up a really bad way to lose weight, it is a proved fact that the stomach acid that comes up when you do that eats the enamel from your teeth so quickly that brushing your teeth straight after you've thrown up does absolutely nothing.\n\nSO STOP DOING IT!!!!!

I love the previous answer! But to put it more clearly, it enables you to vomit.

The anesthesia can make you sick to your stomach. If you have food in your stomach, you could vomit and aspirate (inhale the vomit), causing major problems.

1) Vomiting means emptying your stomach by a strong gag and retch that leads to throwing up. \n\n2) Vomiting is the forceful expulsion of the contents of one's stomach through the mouth. Although it has probably evolved as a mechanism for expelling ingested poisons, vomiting may result from many causes not related to poisoning, ranging from gastritis to brain tumors, or elevated intracranial pressure (ICP). The feeling that one is about to vomit is called nausea. It usually precedes vomiting, but it does not always lead to vomiting. Antiemetics are sometimes necessary to suppress nausea and vomiting, and in severe cases where dehydration develops, intravenous fluid may need to be adminstered.

If you absolutely MUST throw up, SYRUP OF IPECAC makes you throw up. You can find it in most drug stores.  It is used to cause vomiting, so that if you have swallowed something poisonous, you can get it out of your system.  PLEASE make sure that you follow that directions carefully, though, because if you take too much, you can do great harm to your body.  Oh, and next time, do procrastinate som much!  :)    (Been there, done that!)   Good Luck!

It'd be weird if stress didn't cause that. So yeah, my answer is yes, I believe stress can cause you to throw up.

It's stomach acid.  That means that you have no substance in your stomach to throw up.  That's what eats away at your esophagus.
