There is nothing worse than throwing up over a toilet several times a day. If this what are going through or have been through, it is probably the stomach flu. Stomach flu which is medically referred to as Gastroenteritis is an inflammation of the gastrointestinal tract or simply GI tract. GI tract is basically a series of organs in the human body which are connected from mouth to anus. Mouth, esophagus, stomach, small intestine, large intestine and anus makeup the gastrointestinal tract. While the liver, pancreas, and gallbladder are the organs of the digestive system. In short, the gastrointestinal tract is an organ system which takes in food, digests it to take up the energy from the nutrients and expels the waste as feces.

Flu is generally used to name the diseases caused by the Influenza virus, but in this case, gastroenteritis is nowhere related to it because the influenza virus only attacks the respiratory system and not the GI tract. Stomach flu is specifically a term used for various inflammatory problems of the gastrointestinal tract. Gastroenteritis is more commonly caused by viruses like Norovirus, Rotavirus, and others. And rarely, it might be a bacterial infection caused by Staphylococci, Salmonella, Shigella, E.coli, etc..  Keep reading to find out more facts about stomach flu.
