Your stomach heaves. Nausea hits you. You rush to the bathroom for the third time in an hour. And you wonder who to blame: gastroenteritis or food poisoning? Knowing how to differentiate one from the other allows you to take better care of yourself, and above all to avoid recurrences…
Gastroenteritis is a viral infection that causes inflammation of the stomach and intestines. It is sometimes called “stomach flu” in common parlance.

In contrast, symptoms of viral gastroenteritis appear within 24 to 72 hours following exposure to a virus. People with gastroenteritis may take more than a week to get rid of all symptoms.

How to treat food poisoning?
During food poisoning, treatment mainly consists of relieving the symptoms (diarrhea, vomiting, fever, stomach cramps, etc.), the latter of which can be very bothersome.
