Acute Gastroenteritis in Children

Overview

Acute gastroenteritis, commonly known as a stomach bug, is an infection that affects the stomach and intestines, causing symptoms like diarrhea, vomiting, and stomach cramps. It’s a common illness in children, especially those under the age of five. While it can be distressing for both children and their families, it usually resolves on its own within a few days. However, in some cases, medical treatment may be needed, especially if dehydration occurs.

At Gertrude’s Children’s Hospital, we understand how concerning gastroenteritis can be for parents, and our team is here to provide the best care and support for your child.

Symptoms

The symptoms of gastroenteritis can vary from child to child, but common signs include:

  • Diarrhea: Loose or watery stools.
  • Vomiting: Often sudden and can occur several times a day.
  • Stomach cramps: Abdominal discomfort or pain.
  • Fever: A mild fever may accompany other symptoms.
  • Loss of appetite: Children may not want to eat or drink as usual.
  • Dehydration: This is the most serious concern and can lead to symptoms like dry mouth, less urination, sunken eyes, and lack of energy.

If you notice signs of dehydration or if symptoms last more than a few days, it’s important to seek medical care.

Causes

Gastroenteritis is usually caused by an infection, which can be viral, bacterial, or sometimes parasitic. Common causes include:

  • Viruses: 
    • The most frequent cause, with rotavirus, adenovirus and norovirus being the most common culprits. Viral gastroenteritis spreads easily, especially in places like daycare centers or schools.
  • Bacteria: 
    • Certain bacteria, such as Salmonella or E. coli, can cause gastroenteritis. These infections are often linked to contaminated food or water.
  • Parasites: 
    • Parasites like Giardia can also cause gastroenteritis.

Children are more vulnerable to these infections because their immune systems are still developing. Poor hygiene, contaminated food or water, and close contact with others who are sick can all increase the risk.

Diagnosis

Diagnosing gastroenteritis typically involves reviewing your child’s symptoms and medical history. At Gertrude’s Children’s Hospital, we follow a comprehensive process to ensure an accurate diagnosis.

Here’s what the diagnosis process might look like:

  • Medical History and Physical Examination: 
    • The doctor will ask about the symptoms, how long they have been present, and whether your child has been exposed to someone else who was sick. 
    • They will also check for signs of dehydration.
  • Stool Sample: 
    • In some cases, a stool sample may be tested to determine if a bacterial or parasitic infection is present.
  • Blood Tests: 
    • These are rarely needed but may be done to check for dehydration or other complications.

Most cases of gastroenteritis can be diagnosed based on symptoms alone, but testing can help guide treatment if needed.

Treatment Options

The main goal of treatment is to keep your child hydrated and comfortable while the illness runs its course. Most cases of viral gastroenteritis resolve without medical intervention, but it’s important to monitor your child closely. At Gertrude’s Children’s Hospital, we offer various treatment options depending on the severity of the illness.

Hydration:

  • Oral Rehydration Solutions (ORS): 
    • These solutions contain the right balance of salts and sugars to help replenish fluids lost through diarrhea and vomiting. 
    • They are more effective than plain water or juice for rehydration.
  • Intravenous (IV) Fluids: 
    • In more severe cases, where dehydration has set in and the child cannot drink enough fluids, IV fluids may be necessary. 
    • This is done in a hospital setting to ensure your child stays hydrated and recovers safely.

Dietary Adjustments:

  • Once vomiting subsides, it’s important to reintroduce small amounts of food. The BRAT diet (bananas, rice, applesauce, and toast) is commonly recommended for easing back into eating.
  • Breastfeeding or Formula: For infants, continuing breastfeeding or formula feeding is encouraged, as it provides necessary nutrients and fluids.

Medications:

    • Anti-Nausea Medications: 
      • In some cases, anti-nausea medicines may be prescribed to help control vomiting, allowing your child to keep down fluids.
    • Antibiotics: 
      • If the infection is caused by bacteria, antibiotics may be prescribed, but they are not helpful for viral gastroenteritis.
  • Antipyretics: 
  • This is for management of fevers
  • Pain killers/antispasmodics: 
  • This is to alleviate the pain the child may be experiencing

Supportive Care:

  • Rest is crucial for recovery, so keeping your child comfortable and encouraging rest will help them feel better faster.

Acute Gastroenteritis in Children

Most cases of viral gastroenteritis resolve within 3 to 7 days. However, bacterial infections may take longer to recover from, especially if antibiotics are needed.

If your child is showing signs of severe dehydration (such as not urinating, extreme drowsiness, or a dry mouth), or if symptoms persist for more than a few days, it’s important to seek medical care immediately.

Good hygiene, such as regular hand washing, is key to preventing gastroenteritis. Make sure your child avoids contact with sick individuals and consumes only clean, safe food and water. Vaccination against rotavirus, a common cause of viral gastroenteritis, is also available for young children.

It’s essential to keep your child hydrated during gastroenteritis. Offer small sips of water or oral rehydration solutions. When the vomiting subsides, slowly reintroduce bland foods like bananas, rice, and toast.

Yes, viral gastroenteritis is highly contagious. It spreads easily through contact with contaminated surfaces, food, water, or direct contact with an infected person. Isolating the sick child, regular hand washing, and disinfecting surfaces can help prevent the spread.

It’s best to consult your child’s doctor before giving any medications. Over-the-counter remedies for diarrhea or vomiting are not typically recommended for young children as they can sometimes make the illness worse.
