Key Causes of Gastroenteritis

Gastroenteritis, often referred to as "stomach flu," is primarily caused by viral infections. Common culprits include:

• Norovirus: The most frequent cause of viral gastroenteritis in adults.
• Rotavirus: A leading cause in infants and young children.
• Other pathogens: Bacteria (e.g., Salmonella, E. coli) and parasites can also trigger gastroenteritis, though viruses are the dominant cause.

Symptoms of Gastroenteritis

Common Symptoms

• Watery diarrhea
• Abdominal pain or cramping
• Nausea or vomiting
• Fever (in some cases).

Signs of Dehydration

Dehydration is a critical complication. Symptoms vary by age:

Symptom	Adults	Infants/Children
Reduced urination	Urinating less than usual	No wet diaper for 3+ hours
Dry mouth/skin	Dry mouth	No tears when crying
Fatigue	Feeling tired	Lethargy or lack of energy
Dark urine	Dark-colored urine	Sunken eyes or cheeks
Fainting	Light-headedness or fainting	Sunken fontanelle (in infants)

Treatment Tips

Fluid and Electrolyte Replacement

• Adults: Drink clear liquids (water, broth, sports drinks) and eat saltine crackers to restore electrolytes.
• Children: Use oral rehydration solutions (e.g., Pedialyte) as directed. Infants should continue breastmilk/formula.

Over-the-Counter Medications

• Antidiarrheals: Loperamide (Imodium) may reduce diarrhea severity in adults 13.
• Anti-vomiting agents: Bismuth subsalicylate (Pepto-Bismol) or ginger (e.g., ginger tea) may alleviate nausea.

Dietary Adjustments

• Avoid restrictive diets. Resume a normal diet once appetite returns, even with ongoing diarrhea.
• For mild cases, consume bland foods like rice, toast, and bananas

When to Seek Medical Help

• Severe symptoms: Blood in stool, persistent vomiting, or high fever.
• High-risk groups: Infants, elderly adults, or individuals with weakened immune systems showing dehydration signs.

If symptoms persist or worsen, consult our Gastroenterology & Hepatobiliary specialists at Jeevandan Health for proper diagnosis and treatment.

Prevention

• Practice thorough handwashing.
• Avoid undercooked food and contaminated water.
