Self-Care for Viral Colitis
For viral colitis, focus on oral rehydration with fluids containing physiological concentrations of glucose and electrolytes, strict hand hygiene with soap and water after toilet use and before eating, and temporary avoidance of swimming and sexual contact until symptoms resolve 1.
Hydration Management
The cornerstone of self-care is preventing and treating dehydration through oral rehydration therapy 2. This approach is as effective as intravenous fluids for mild-to-moderate dehydration and should be the first-line strategy 2.
- Use oral rehydration solutions with appropriate glucose and electrolyte concentrations
- Drink fluids frequently in small amounts to compensate for gastrointestinal losses
- For persistent vomiting that interferes with oral intake, consider seeking medical attention for possible ondansetron use (for those >4 years of age) 1
Medication Considerations
Avoid antimotility agents (like loperamide) if you have fever or bloody diarrhea, as these can lead to toxic megacolon 1. This is a critical safety consideration—while these medications may be used cautiously in simple watery diarrhea in adults, they should never be used when inflammatory features are present.
Probiotics may be considered to reduce symptom severity and duration, though specific organism selection should be guided by available literature 1.
Hygiene and Transmission Prevention
Hand hygiene is paramount and must be performed:
- After using the toilet
- After changing diapers
- Before and after preparing food
- Before eating
- After handling garbage or soiled laundry 1
Use soap and water rather than alcohol-based sanitizers alone, as certain viral pathogens (like norovirus) are less susceptible to alcohol 1.
Activity Restrictions
While symptomatic with diarrhea:
- Avoid swimming and water-related activities
- Avoid sexual contact with others
- Maintain meticulous hand hygiene throughout 1
These restrictions protect others from transmission and should continue until symptoms fully resolve.
Food Safety
Practice appropriate food handling to prevent secondary transmission:
- Avoid cross-contamination during food preparation
- Ensure proper cooking temperatures for meats and eggs
- Maintain proper food storage temperatures 1
When to Seek Medical Care
Viral gastroenteritis is typically self-limiting 2, 3, but seek medical attention if:
- Signs of severe dehydration develop (decreased urination, extreme thirst, dizziness)
- High fever persists
- Bloody diarrhea occurs
- Symptoms worsen or don't improve after several days
Common Pitfall: Many people use antimotility agents at the first sign of diarrhea without recognizing warning signs like fever or blood in stool. This can be dangerous and potentially lead to complications like toxic megacolon 1.
