Drink Plenty of Fluids
According to the NSW government’s health website, it is ideal to drink plenty of clear fluids to treat gastroenteritis. This includes water and diluted juice to prevent dehydration.
Consider Taking Oral Rehydration Drinks
Rehydration drinks, which temporarily replace fluids and salts, are also available from chemists. They are available online and over the counter, and you may even put them in your first aid kit.
Ask Prescription for Antibiotics
A health professional may prescribe antibiotics if hospital tests confirm that bacteria caused the gastroenteritis.
Consult About Antiparasitic Drugs
A doctor may recommend taking drugs to kill parasites if they are the cause of gastroenteritis.
Undergo an Intravenous Fluid Replacement
For severe conditions, a doctor may have to administer fluid to your body through a needle or a tube.
What to Eat When You Have Gastroenteritis?
Healthdirect, an information service funded by the Australian government, recommends eating the following easy-to-digest food when one’s appetite returns.
- Plain crackers
- Toast
- Banana

It also discourages consuming milk, dairy, and undiluted drinks as the sugar in these may worsen diarrhoea.
What is Gastroenteritis?
Gastroenteritis occurs when infection and inflammation trigger the digestive system. Its main complication is dehydration, so treatments focus on replacing the fluid in the body to prevent it.
What Causes Gastroenteritis?
The following factors may cause infection and inflammation in the digestive system.
- Viruses
- Bacteria or bacterial toxins
- Parasites
- Chemicals
- Medication
Any of the above causes may then lead to gastroenteritis.
How Can You Get Gastroenteritis?
Infectious gastroenteritis occurs due to viruses, bacteria, or parasites that spread through the following.
- Escherichia coli infection – occurs most often in travellers
- Campylobacter infection – from food with bacteria
- Cryptosporidium infection – due to swallowing water with parasites
- Giardiasis – parasite infection after handling infected animals or following poor hygiene
- Salmonellosis – from the consumption of contaminated food
- Shigellosis – spread through food or surfaces
- Viral gastroenteritis – through person-to-person contact
Most of these cases occur when there is an ingestion of an agent.
What are the First Signs of Gastroenteritis?
The following symptoms may show if you have gastroenteritis.
- Appetite loss
- Bloating
- Nausea
- Vomiting
- Cramps or pain in the abdominal area
- Diarrhoea
- Blood or pus in the stool
- General feelings of unwellness, such as lethargy and body aches
If you experience any of these, consult a doctor who will recommend the ideal treatment for gastroenteritis after diagnosing it through examination and tests.
How to Prevent Gastroenteritis?
Aside from regular handwashing, doing the following may also help avoid gastroenteritis.
- Opt for disposable paper towels over cloth towels, as bacteria may survive on the latter.
- Do not use kitchen items on food unless these went a thorough washing
- Keep kitchen surfaces and equipment clean
- Cook food thoroughly
- To prevent bacteria growth, keep cold food cold (below 5 °C) and hot (above 60 °C).
- Clean the toilet and the bathroom regularly
- Drink bottled water only in countries where sanitation is suspect
Hand washing with soap and water is also more effective in preventing infection than hand sanitisers.
Conclusion
Plenty of fluids, oral rehydration drinks, antibiotics, antiparasitic drugs, and undergoing intravenous fluid replacement help treat gastroenteritis. Eating easy-to-digest food such as crackers and bananas is ideal when your appetite returns. Gastroenteritis occurs when an infection and inflammation in the digestive system causes symptoms and possible dehydration. Viruses, bacteria, chemicals, and certain medications cause it, which you may get through food, poor hygiene, surfaces, and direct contact with people. Fortunately, it is still possible to avoid it with regular handwashing and other hygienic measures. If you’d like to learn more about various medical conditions and how to handle them, going through first aid training is a good option. While you or someone you know may not be going through gastroenteritis, taking first aid and even CPR training puts one in the right mindset for safety.
