Many have their own special terms for stomach and intestinal related illness such as, “My daughter had the ‘stomach bug’ last week and now it is going through the whole house.” Or, “I had vomiting and diarrhea all night. What misery! I think I had the ‘stomach flu.’”
The “stomach bug” or “stomach flu” is actually gastroenteritis, which is not the same as the influenza virus. Influenza or “flu” usually does not cause symptoms such as vomiting or diarrhea. So, what is gastroenteritis and what causes this distress?
Gastroenteritis is an inflammation of the stomach and small and large intestines. Symptoms are diarrhea, nausea or vomiting, abdominal cramps, and often a fever. Gastroenteritis is caused by viruses, bacteria or parasites.
