Management of Viral Gastroenteritis in a 37-Year-Old Female

The primary treatment for viral gastroenteritis in a 37-year-old female is oral rehydration therapy (ORT) to prevent dehydration and electrolyte imbalance, as the condition is typically self-limited and resolves within a few days. 1

Rehydration Therapy

• Oral rehydration is the cornerstone of treatment for viral gastroenteritis, focusing on maintaining adequate hydration status 1
• For adults with mild to moderate dehydration, oral rehydration solutions (ORS) are as effective as intravenous fluid therapy 2
• Hypotonic oral rehydration solutions have been shown to be more effective than standard solutions 3
• Commercial solutions like Gatorade can be as effective as medical rehydration solutions like Pedialyte for adults with mild viral gastroenteritis 2
• Intravenous fluids should be reserved only for cases with severe dehydration or when the patient cannot tolerate oral rehydration 4, 1

Nutritional Management

• Early refeeding is recommended as it decreases intestinal permeability caused by infections and improves nutritional outcomes 1
• Regular diet can be resumed as tolerated, with no need for specific dietary restrictions 1
• Temporary lactose intolerance may occur following viral gastroenteritis but usually resolves within 10-14 days 4

Symptomatic Treatment

• Bismuth subsalicylate may provide symptomatic relief, with evidence showing reduction in Norwalk virus infection duration from 27 to 20 hours 4, 1
• Antiemetics may be considered if vomiting is significant and preventing adequate oral hydration 1, 5
• Antimotility drugs (e.g., loperamide) may be considered for immunocompetent adults with acute watery diarrhea but should be avoided if there is fever or bloody diarrhea 1

Monitoring and Warning Signs

• Monitor for signs of severe dehydration including decreased urine output, dry mouth and tongue, sunken eyes, and unusual drowsiness 1
• Medical attention should be sought if unable to keep down fluids, signs of severe dehydration develop, or symptoms persist beyond 3-4 days 1
• Electrolyte abnormalities (particularly hypokalemia and hyponatremia) should be monitored in patients with prolonged symptoms 2

Prevention of Transmission

• Vigorous handwashing with soap for at least 10 seconds after each contact with ill persons is necessary to control spread 4
• If the patient is a food handler or healthcare worker, they should be excluded from work for at least 2 days after resolution of symptoms 4
• Environmental surfaces should be kept clean, with special attention to areas soiled by feces or vomitus 4
• Soiled linens and clothes should be handled minimally and washed promptly with detergent at maximum cycle length 4

Special Considerations

• Viral gastroenteritis is self-limited with virus replication restricted to the gut mucosa 4, 6
• The main risk is dehydration and electrolyte imbalance rather than the infection itself 4
• Laboratory testing is generally not necessary unless symptoms are severe, prolonged, or atypical 5
• Common causative agents include rotavirus, norovirus, adenovirus, and caliciviruses, but specific antiviral therapy is not recommended for immunocompetent adults 3, 6
