Other pathogens: Bacteria (e.g., Salmonella, E. coli) and parasites can also trigger gastroenteritis, though viruses are the dominant cause.

Fluid and Electrolyte Replacement

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

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.
