Clinical Pathway of Acute Gastroenteritis: From Onset to Recovery

1. Incubation Period

Hours to days, varies by pathogen.

2. Symptom Onset

Sudden or gradual: diarrhea, abdominal pain/cramps, nausea, vomiting, fever, headache, muscle aches.

3. Evaluation & Diagnosis

History, physical, stool analysis/culture to identify pathogen.

4. Treatment

• Fluids/electrolytes (oral rehydration solutions).
• Antidiarrheals (e.g., loperamide) if appropriate.
• Antiemetics for nausea/vomiting.
• Antibiotics only for severe bacterial cases (not viral).
