Gastroenteritis is an infection of the stomach and intestines that commonly causes diarrhoea, vomiting, and stomach cramps. It is often referred to as a “stomach bug” and is usually caused by viruses,
The infection spreads easily through close contact with infected people, contaminated food or water, or by touching contaminated surfaces and then touching your mouth.
Most cases of gastroenteritis improve on their own within a few days. However, it can sometimes lead to dehydration, particularly in young children, older adults, and people with weakened immune systems.

Is Gastroenteritis a Valid Reason for a Sick Note?
Yes, gastroenteritis can be a valid reason for a sick note if symptoms prevent you from carrying out your normal work duties.

Frequently Asked Questions
How Long Does Gastroenteritis Last?
Most people recover within a few days. Diarrhoea may last for up to a week, while vomiting usually settles more quickly. Recovery times can vary depending on the cause of the infection.
Is Gastroenteritis Contagious?
Yes. Gastroenteritis is highly contagious and can spread through close contact with infected people, contaminated food or water, and contaminated surfaces.
What Should I Eat If I Have Gastroenteritis?
It is important to stay hydrated by drinking plenty of fluids. Eat small, simple meals if you feel able to, and return to your normal diet as tolerated. If eating makes you feel worse, focus on fluids until your appetite returns.
How Can I Prevent Dehydration?
Take frequent small sips of water or oral rehydration solutions, especially after episodes of diarrhoea or vomiting. Seek medical advice if you are unable to keep fluids down.
When Can I Return to Work or School After Gastroenteritis?
To help prevent spreading the infection, people with diarrhoea or vomiting are generally advised to stay away from work, school, or childcare settings until they have been free of symptoms for at least 48 hours.
Is Gastroenteritis the Same as Food Poisoning?
Not always. Food poisoning is one possible cause of gastroenteritis. Gastroenteritis can also be caused by viruses, bacteria, or parasites that are not necessarily linked to food.
Should I Take Antibiotics for Gastroenteritis?
Usually not. Most cases are caused by viruses, and antibiotics do not work against viral infections. Antibiotics may occasionally be prescribed for certain bacterial infections.
