Although no one likes it, everyone will experience vomiting at one time or another.  Vomiting occurs when the stomach moves food up and out, instead of down through the digestive tract.  In the majority of cases, vomiting can be treated at home with fluids.  In severe instances, such as with poisoning, vomiting should be treated by emergency medicine professionals.


Whenever you eat or drink, food travels through your digestive system for processing.  Your body absorbs nutrients and removes waste products via the digestive system.  When you eat, your tongue moves chewed food to the back of your throat.  When you swallow, the food moves into the opening of the esophagus.  Your esophagus is a tube that moves food from your throat to your stomach.

Your stomach produces acids to break down food for digestion and processes it into a liquid form.  The liquid travels from your stomach to your small intestine, where it is further processed, sent to the large intestine, and eventually eliminated from your body.


Vomiting is caused by many things.  Infections, motion sickness, morning sickness during pregnancy, medications, migraines, food poisoning, alcohol, and food allergies are common causes of vomiting.  When you vomit, the muscles around your stomach push food up the esophagus and out of the throat.


Vomiting causes food to move up out of the stomach and through the throat and mouth.  You may feel nausea and have an increase in saliva before you vomit.  Your throat may burn and you may have a bad taste in your mouth.


The majority of cases of vomiting do not require medical attention.  However, you should contact your doctor if you experience severe vomiting, vomiting which lasts for several days, or if you cannot keep any food or fluid in your stomach.  You doctor will examine you and conduct lab tests to help determine the cause of your vomiting.


In the majority of cases, vomiting is treated with rest and fluids.  It is important to drink fluids to stay hydrated.  It may be easier to consume fluids in small amounts.  People with severe dehydration may need IV fluids and hospitalization.
