does the flu affect your stomach
Report Abuse. Adults don't usually vomit when they have Influenza but some children do. I think it's mostly the hight fever that causes children to vomit. Some people are uninformed about what the flu really is. When ever they get a stomach virus or food poisoning, they call it the flu. Some call it the stomach flu.
Flu, also called influenza, typically causes fever and/or chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, and fatigue. Sometimes the flu also causes vomiting and diarrhea, but this is more common in children than in adults.
