Why Probiotics May Not Be the Solution for Kids with Stomach Flu

Stomach flu, also known as viral gastroenteritis, is a common illness among children, especially during the winter months. It can cause vomiting, diarrhea, and stomach pain, making it a miserable experience for both kids and parents. In an effort to help their child recover quickly, some parents may turn to probiotics. Probiotics have been promoted as a cure-all for various health conditions, including digestive problems. However, when it comes to stomach flu, the use of probiotics may not be necessary.

What Are Probiotics?

Before we delve into the reasons why probiotics may not be effective in treating stomach flu in kids, it’s important to understand what probiotics are. Probiotics are live bacteria and yeasts that are naturally found in the gut. They are often referred to as “good” bacteria because they help maintain a healthy balance of microorganisms in the gut. Probiotics are available in supplement form or can be found in certain foods, such as yogurt, kefir, and sauerkraut.

What Is Stomach Flu?

Stomach flu is caused by a virus that attacks the digestive system. The most common culprits are the norovirus and the rotavirus. It’s highly contagious and spreads easily through contact with infected people, surfaces, and objects. Symptoms of stomach flu include nausea, vomiting, diarrhea, stomach cramps, and fever. It’s important to note that stomach flu is not the same as the flu, which is a respiratory illness caused by the influenza virus.

Why Probiotics May Not Be Necessary for Stomach Flu

While probiotics are often touted as a way to boost gut health and improve digestion, they may not be the best solution for stomach flu. Here are a few reasons why:

  1. Probiotics May Not Work for Viral Infections

Stomach flu is caused by a virus, and probiotics may not be effective in fighting viral infections. The norovirus and rotavirus are highly contagious and can cause severe symptoms. In some cases, the virus may need to run its course, and probiotics may not be able to speed up the healing process.

  1. Probiotics May Cause Digestive Upset

While probiotics are generally considered safe, they may cause digestive upset in some people. When your child is already experiencing stomach flu symptoms, adding more bacteria to their gut may worsen their symptoms. Probiotics can also cause gas, bloating, and diarrhea in some people.

  1. Probiotics May Interfere with Other Treatments

If your child is taking medication to manage their stomach flu symptoms, probiotics may interfere with the effectiveness of the medication. It’s always a good idea to check with your child’s doctor before adding any new supplements to their routine.

What Are Some Alternatives to Probiotics?

If your child has stomach flu, there are other things you can do to help them feel better. Here are a few suggestions:

  1. Stay Hydrated

One of the most important things you can do when your child has stomach flu is to keep them hydrated. Encourage them to drink plenty of fluids, such as water, broth, or electrolyte solutions like Pedialyte. Dehydration is a common complication of stomach flu, and it can be serious, especially in young children.

  1. Rest

Rest is important when your child is sick. Encourage your child to rest as much as possible to help their body recover. Avoid activities that may make them feel worse, such as physical activity or eating large meals.

  1. Offer Small, Frequent Meals

When your child is ready to

eat again, offer them small, frequent meals throughout the day. This can help prevent nausea and vomiting, and it can also help their body absorb nutrients more efficiently. Stick to bland foods like crackers, toast, bananas, and rice until your child’s stomach settles.

  1. Use Over-the-Counter Medications

Over-the-counter medications like acetaminophen can help manage fever and pain. However, be cautious when giving medications to children and follow the recommended dosage.

  1. Practice Good Hygiene

To prevent the spread of stomach flu, it’s important to practice good hygiene. Encourage your child to wash their hands regularly, especially after using the bathroom or before eating. Make sure they don’t share utensils, cups, or towels with other family members or friends.

When to See a Doctor

In most cases, stomach flu will go away on its own within a few days. However, if your child’s symptoms are severe, or if they are not improving, it’s important to see a doctor. In some cases, stomach flu can lead to dehydration, which can be dangerous, especially in young children. If your child is showing signs of dehydration, such as dry mouth, infrequent urination, or dark urine, seek medical attention immediately.


In conclusion, while probiotics may be beneficial for gut health, they may not be necessary for kids with stomach flu. Instead, focus on keeping your child hydrated, resting, and offering small, frequent meals. Use over-the-counter medications to manage symptoms, and practice good hygiene to prevent the spread of the virus. If your child’s symptoms are severe or not improving, seek medical attention. With proper care, your child will be back to their happy and healthy self in no time.
