What You'll Learn

Hydration is key
Gastroenteritis, also known as the stomach flu, is a highly contagious infection that causes inflammation of the stomach and intestines. Symptoms include nausea, vomiting, diarrhoea, stomach cramping, abdominal pain, and fatigue. The inflammation caused by gastroenteritis can speed up the movement of food through the digestive tract, leading to these unpleasant symptoms.
In addition to broth-based soups, there are other ways to stay hydrated while managing gastroenteritis. Clear broths, ice chips, and sports drinks or hydration formulas can help with fluid intake. For children, it is essential to replace lost fluids and salts, and an oral rehydration solution may be recommended. It is important to note that if dizziness or lightheadedness occurs, and fluid intake is insufficient, medical attention should be sought.
While staying hydrated is crucial, it is also important to introduce bland, easy-to-digest foods gradually. The stomach and intestines may not be able to handle complex or heavy foods during the acute phase of gastroenteritis. Therefore, it is recommended to start with bland, refined grains, plain potatoes, eggs, unsweetened applesauce, and other gentle foods. As you begin to tolerate more solid foods, the BRAT diet (bananas, rice, applesauce, and toast) is a good foundation for transitioning back to a normal diet. These foods are bland and easy to digest, providing nourishment without irritating the stomach.
In summary, hydration is a critical aspect of managing gastroenteritis. The condition can lead to dehydration due to vomiting and diarrhoea, and maintaining fluid balance is essential. By consuming hydrating foods and beverages and gradually introducing bland, easy-to-digest options, individuals with gastroenteritis can support their bodies' recovery and minimise discomfort.

Bland foods are best
When suffering from gastroenteritis, it is important to remember that your stomach and intestines are inflamed, making it difficult for your body to digest or absorb food. This inflammation can also increase the speed at which food moves through your digestive tract, causing fatigue, diarrhoea, cramps, nausea and vomiting.
- Soda crackers
- Toast
- Bananas
- Rice
- Chicken
- Eggs
- Applesauce
- Refined grains
- Plain potatoes
- Oats
- Noodles
- Broth-based soups
These foods are not too spicy, sharp, rich or fatty, and will not irritate your stomach further. They will also not worsen your nausea and vomiting, as drinking too much liquid at once might.
It is also important to stay hydrated, as gastroenteritis can cause dehydration. However, be careful not to drink too much liquid at once.

Avoid caffeine
When experiencing gastroenteritis, it is important to avoid caffeine. Caffeine is a stimulant that can increase acid production in the stomach and cause further irritation to the digestive tract. It is also a diuretic, which means it can lead to increased fluid loss and dehydration, which is especially problematic when experiencing vomiting and diarrhoea.
Caffeinated drinks, such as coffee and tea, are best avoided when suffering from gastroenteritis. Instead, focus on staying hydrated by drinking plenty of water. Clear broths are also recommended as they have a high water content and can help with hydration. They are also a good source of sodium, an electrolyte that can become depleted due to frequent vomiting and diarrhoea.
In addition to caffeine, it is advisable to refrain from consuming spicy, fried, and fatty foods, as well as milk and milk products. These foods can aggravate symptoms and slow down the recovery process. Instead, opt for bland, easily digestible foods such as bananas, rice, applesauce, toast, and plain potatoes. These foods are gentle on the stomach and can help settle it while providing essential nutrients.
Sports drinks and soft drinks should also be avoided due to their high sugar content, which can trigger symptoms. Instead, choose rehydrating beverages with electrolytes to replenish lost fluids and minerals. It is crucial to listen to your body and allow your digestive system to rest while gradually introducing gentle foods to aid in your recovery.
By avoiding caffeine and other irritating foods, you can help soothe your stomach, prevent complications, and promote a faster recovery from gastroenteritis. Remember to stay hydrated and provide your body with the nourishment it needs during this time.

Gastroenteritis, commonly known as the stomach flu, is a highly contagious intestinal infection that affects the stomach and intestines. Common symptoms include nausea, vomiting, diarrhoea, stomach cramping, and abdominal pain. It is important to stay hydrated when suffering from gastroenteritis, as frequent vomiting and diarrhoea can lead to a depletion of fluids and electrolytes.
After the stomach has settled, it is recommended to start with small meals of bland, low-residual foods such as mashed potatoes, plain noodles, crackers, toast, gelatin, bananas, rice, and chicken. These foods are easy to digest and can help prevent further complications.
It is generally recommended to avoid fatty foods when recovering from gastroenteritis, as they can be difficult for the body to digest and may slow down the recovery process. Instead, focus on eating bland, easily digestible foods and staying hydrated by drinking clear fluids such as broth, ice chips, or water.
Once you can tolerate these bland foods, you can slowly transition back to your normal diet. However, it is important to listen to your body and introduce new foods gradually to avoid triggering any symptoms. Overall, avoiding fatty foods and following a gentle diet can help manage gastroenteritis symptoms and speed up recovery.

Ease back into eating
When you have gastroenteritis, it's important to take it slow when it comes to reintroducing food to your diet. Here are some tips to ease back into eating:
Start with Clear Fluids
Initially, it's best to focus on hydration. Drink clear fluids such as water, ice chips, or broths in small amounts to avoid worsening nausea and vomiting. This helps to replenish the fluids lost due to vomiting and diarrhea, which are common symptoms of gastroenteritis.
Introduce Bland, Easy-to-Digest Foods
Once you can tolerate clear fluids, it's time to introduce bland, low-residual foods that are gentle on your stomach. These include bananas, rice, applesauce, toast (the BRAT diet), crackers, plain grits, plain oatmeal, refined grains, and plain potatoes. Eggs are also an option, as they are easy to digest. These bland foods are recommended by health professionals because they are less likely to irritate your stomach.
Avoid Irritating Foods
Stay away from foods and drinks that can irritate your stomach or make your symptoms worse. These include caffeine, high-fat foods (such as fried foods and fast food), milk and milk products (due to lactose), and beverages with large amounts of simple sugars. Spicy foods should also be avoided as they can make vomiting and diarrhea more uncomfortable.
Monitor Your Progress
As you gradually incorporate more foods back into your diet, pay attention to how they make you feel. The recovery timeline varies from person to person, so listen to your body and adjust your diet accordingly. Most people feel better and return to their usual diet within about a week, but it's important to take it at your own pace.
Remember, the BRAT diet alone may not provide all the nutrients your body needs, so make sure to include other gentle foods as well. Always consult with a healthcare professional if you have specific concerns or questions about your diet during the recovery process.
