• Abdominal pain or cramping
• Nausea
• Vomiting

Symptoms (continued)
• Unintentional weight loss (a sign of dehydration)
• Excessive sweating• Clammy skin• Muscle pain or joint stiffness• Incontinence (loss of stool
control)
Signs of dehydration
• Extreme thirst
• Dark urine
• Dry skin
• Dry mouth
• Sunken cheeks or eyes
• In infants, dry diapers (for more than 4-6 hours)
Diagnosis
• Medical history
• Physical examination
• Stool culture
DD
• Pneumonia
• Septicemia
• UTI
• Meningitis
• Appendicitis
• Intussusception
• Hirschsprung’s disease
Treatment
• Replacement of fluids and electrolytes
• Antibiotics if it’s bacterial
Prevention
• Washing hands
• Cleaning and disinfection
• Safe water
• Food sanitation
