Hi, how does pain induce vomiting?

Pain and vomiting: Pain cause large amount of prostaglandins to be released which can cause vomiting as well as diarrhea.

CRT Zone: Any pain can stimulate chemo receptor trigger zone which causes vomiting.

Poor Treatment: Not sure why you would desire to induce vomiting but this old treatment to get rid of poisons but vomiting has since gone of favor. Vomiting can cause damage to the lining of your esophagus and erode the dental enamel if done repeatedly. If you have ingested something undesirable, bringing it back up can cause even worse damage.

Many ways: Vomiting is a reflex designed to rid the body of toxic substances in the stomach or to empty the stomach if the body fears it will be too busy doing something important to waist energy on digestion at the moment.. If you are in pain you may hyperventilate which causes nausea and vomitting. This webpage will also help... http://www.myvmc.com/symptoms/nausea-and-vomiting-emesis/
