What is Stomach Flu (Gastroenteritis)?
Stomach flu, often called “gastroenteritis” or “gastric flu”, is an inflammation of the stomach and intestines.
It is commonly caused by infections from viruses, bacteria, or parasites. This condition can lead to uncomfortable symptoms, but it usually resolves on its own with proper care.
Symptoms of Stomach Flu
Common symptoms of stomach flu include:
- Nausea and vomiting: This can be very uncomfortable and lead to dehydration. To soothe these symptoms, try sipping clear fluids or herbal teas like ginger tea.
- Diarrhoea: Frequent loose or watery stools can occur. Staying hydrated is essential. Consider using electrolyte solutions to replenish lost fluids.
- Stomach cramps: Gentle heat, like a warm compress, can help ease cramping.
- Fever: A mild fever may occur. Rest is important, and over-the-counter medications can help reduce fever.
Causes of Stomach Flu
Many different viruses can infect your gastrointestinal system, causing gastroenteritis. The most common ones are:
- Norovirus: This is the leading cause of stomach flu in adults, accounting for about 50% of cases worldwide. It is very resistant to temperature and disinfectants.
- Rotavirus: This virus is the leading cause of stomach flu in children worldwide. Most children get it before age three, which is why most adults are immune. There is now a vaccine available.
- Astrovirus: Astroviruses mostly affect children younger than three. They commonly spread through daycare centres and can also spread in elder care homes.
- Adenovirus: Although more often linked to respiratory infections, adenoviruses can also cause gastrointestinal infections if ingested.
How Common is Stomach Flu
Stomach flu is quite common. Millions of people experience gastroenteritis each year.
It is especially prevalent during the winter months. Outbreaks often occur in crowded places, like schools and nursing homes.
Stomach Flu in Children
Children are particularly susceptible to stomach flu. Their immune systems are still developing. They may show symptoms like vomiting and diarrhoea more severely. It is crucial to monitor them closely to prevent dehydration.
Does Stomach Flu Cause Gas?
Yes, Stomach Flu inflames the stomach and intestines. The inflammation and disruption in normal digestion can create bloating and excess gas. Additionally, as your body fights off the virus, the balance of gut bacteria can temporarily shift that can result in gas production.

Many natural remedies can help alleviate symptoms:

Stomach flu typically lasts for 1 to 3 days. However, the contagious period can last from a few days to two weeks, depending on the cause. It is essential to practise good hygiene to prevent spreading the virus to others.
What Should You Eat?
When recovering from stomach flu, start with bland foods. Some recommended options include:
- Bananas

These foods are gentle on the stomach and can help firm up stools.

Seek medical attention if you or your child experiences:
- Severe dehydration (dry mouth, dizziness, little or no urination)
- Persistent vomiting that prevents keeping fluids down
- High fever (over 39°C or 102°F)
