Diarrhea from Gastroenteritis


Around 20% of people catch stomach flu every year, and they usually have diarrhea.

What is Stomach Flu (Gastroenteritis)?

Viral or bacterial gastroenteritis is a common condition where the stomach and intestines are irritated and inflamed - what you might call a stomach bug.

What causes Stomach Flu?

The most common causes of gastroenteritis are:

  • Viruses (Norovirus in adults, Rotavirus in children)
  • Drinking contaminated water (travellers’ diarrhea)
  • Food poisoning

What are the symptoms of Stomach Flu?

While acute diarrhea is the main symptom of gastroenteritis, you might also experience nausea, vomiting, headache or mild fever. Symptoms usually pass in a few days.

How to avoid catching or spreading it

If your gastroenteritis is caused by Norovirus, it will be highly contagious. So be careful not to spread it to other people.
