What is Pediatric Gastroenteritis?

Gastroenteritis is acute infection of the gastrointestinal tract. Viral pathogens, primarily rotavirus and norovirus, account for 70-80% of childhood gastroenteritis. It is a major cause of mortality and hospital admission in children under five worldwide.

Dehydration is the most serious complication of gastroenteritis. Mild dehydration (3-5% fluid loss) can be managed at home with oral rehydration, while moderate to severe dehydration requires hospitalization for IV fluid replacement.

Rotavirus vaccines (RV1, RV5) have reduced rotavirus gastroenteritis and related hospitalizations by 60-80% in developing countries.

Symptoms

Watery or mucoid diarrhea
Nausea and vomiting
Abdominal pain and cramps
Fever
Loss of appetite
Signs of dehydration: dry mouth, sunken eyes, decreased urine output, no tears when crying

Risk Factors

Under 2 years of age (immune system and gastric acidity not yet fully developed)
Group settings (daycare, nursery)
Inadequate sanitation and poor hand hygiene
Lack of rotavirus vaccination
Not breastfeeding
Malnutrition

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Any diarrhea in an infant under 6 months
  • When bloody or black stool is observed
  • When signs of dehydration appear (sunken eyes, no tears when crying)
  • Fever ≥39°C or lasting more than 72 hours
  • ER if altered consciousness or seizure occurs

Treatment Methods

01
Oral rehydration solution (ORS): 50-100 mL/kg in the first 4 hours
02
Early refeeding: fasting not recommended; continue age-appropriate diet
03
Intravenous fluids: severe dehydration or intolerance to ORS
04
Antiemetic: ondansetron, when vomiting prevents ORS tolerance
05
Probiotics (Lactobacillus GG or S. boulardii): shorten duration of diarrhea
06
Antibiotics: only in severe cases with proven bacterial etiology
