If you notice that your child is experiencing stomach discomfort, there is a chance that they may have gastroenteritis. If this occurs more often, they may have what doctors call recurrent gastroenteritis in children.

Here are some important facts about gastroenteritis – from causes to symptoms and home remedies for gastroenteritis in toddlers.

Signs and Symptoms

It can be easy to confuse gastroenteritis for diarrhea, as diarrhea is one of the main symptoms. (Diarrhea, however, is caused by parasites or bacteria like E. coli, salmonella, etc.)

Gastroenteritis is an infection of the stomach and small intestines that is caused typically by a virus or bacteria, and a parasite. The infection causes a person’s intestines and stomach to become inflamed and irritated.

People often call it the “stomach flu,” but it is not the same as influenza. Real influenza or flu affects the respiratory system, while gastroenteritis attacks the intestines. The most common virus that causes gastroenteritis is rotavirus.

Gastroenteritis causes the following symptoms: 

  • Watery diarrhea. Typically, it is non-bloody. If you notice that there is blood in your stool, you may have a different kind of infection that is more severe. If this occurs, consult your doctor.
  • Abdominal pain and cramps
  • Vomiting and nausea can often appear along with other symptoms 
  • Headaches
  • Muscle aches
  • Low-grade fever

Gastroenteritis can range in severity. For mild cases, people may experience mild diarrhea and an upset stomach with mild symptoms for 1-2 days.

However, in more severe cases, people may experience vomiting and severe diarrhea that may last longer. 

When should we see a pediatrician?

If your child cannot tolerate any liquid or solid food, is lethargic or experiencing persistent vomiting, please bring the child to the hospital.

What causes gastroenteritis in children?

You can contract the virus or bacteria that causes gastroenteritis via person-to-person contact or by touching vomit, feces, or an infected person’s hands. Another way you can get it is by consuming contaminated food or drinks.

If you are wondering how recurrent gastroenteritis in children occurs, it is usually due to poor personal hygiene.

For instance, your child may contract it by touching an animal that has virus/ bacteria. It is important to teach your children to regularly wash their hands and help them learn how to avoid contaminated drinks and food.

Proper Hand Washing: All You Need To Know

Contaminated food and drinks do not always mean “dirty” food and drinks. There is a chance that a person can get gastroenteritis by consuming unpasteurized juice or milk, contaminated shellfish, inadequately cooked eggs, or meat. 

Possible Complications of Gastroenteritis

A serious condition for most people, especially young children and babies who are prone to dehydration, is acute gastroenteritis with dehydration. While many cases of gastroenteritis tend to be mild and manageable, some cases can develop into hypoglycemia and dehydration due to prolonged diarrhea and vomiting.

Other complication includes electrolyte abnormalities and irritant diaper dermatitis.

Dehydration: Applying First Aid


While the symptoms of gastroenteritis are easy to spot, it is easy to confuse the condition with other health issues. Therefore, it would be best to bring your child to the doctor, especially if they are showing signs of dehydration, to diagnose them properly.

At the consultation, your doctor will perform a routine physical exam on your child and may ask about your child’s medical history.

In some cases, the doctor may request for a stool sample to better diagnose the condition. This is usually necessary if a child experiences severe symptoms and has endured them for more than 48 hours.

History and physical exam is important. Laboratory evaluation may be done as well: aside from stool stample, CBC, electrolytes and stool studies.

Lifestyle Changes and Home Remedies

If your child experiences severe symptoms, it is best to take them to the doctor right away. The symptoms of gastroenteritis can be taxing on a child, especially in babies and young children. A doctor would also be able to prescribe the appropriate type of treatment for your child’s case. 

If your child is experiencing very mild symptoms, you can try safe and effective home remedies for gastroenteritis in toddlers. An excellent way to help a child recover faster is by making sure that they drink enough fluids and get enough bed rest. For babies, breastfeeding may be ideal to help them stay hydrated.

You should avoid giving your child drinks that contain sugar or caffeine or dairy products, as these can worsen diarrhea, causing them to lose more fluids. However, if your child is frequently vomiting, it would be ideal to offer them regular yet small amounts of liquid, increasing the amount throughout the day. It would be wise to not force them to drink a lot of water right away, because it may shock their stomach.

Additionally, one of the approved home remedies for gastroenteritis in toddlers is to put your child on a tummy-friendly diet. Offer them easily digestible foods that will not irritate their stomach. Even if your child is not lactose-intolerant, it may be wise to avoid giving them dairy for a while.

It is also important to note that prevention is better than cure. For instance, one type of virus that can cause gastroenteritis is rotavirus. To avoid acute gastroenteritis (age in infants) in infants, have your children get their rotavirus vaccination to prevent severe symptoms like vomiting and diarrhea from developing. 

As another preventive measure, it would be ideal to teach your children to properly and regularly wash their hands. If they are unsure about whether food is safe to eat, teach them to avoid it 

If you have any questions, please consult with your doctor to better understand the best solution for you.

Gastroenteritis can be either mild or severe. It is a condition that must be closely monitored especially if it develops into recurrent gastroenteritis in children. Remember the tips above to better protect your child, and consult your doctor for any concerns.
