Treatment of Acute Diarrhea in Pregnancy at Term

Oral rehydration therapy (ORT) is the cornerstone of treatment for acute diarrhea in pregnancy at term, with continued normal diet and avoidance of antimotility medications such as loperamide due to safety concerns.

Hydration Management

Hydration is the primary focus of treatment for acute diarrhea in pregnancy at term:

  • First-line treatment: Oral rehydration solution (ORS) to replace fluid and electrolyte losses 1
  • Dosing: Administer approximately 10 mL/kg of ORS after each loose stool 1
  • Ongoing losses: Replace each episode of vomiting with 2 mL/kg of fluid 2
  • Monitoring: Track frequency of urination, stool consistency, and signs of dehydration

Signs of Dehydration Requiring Medical Attention

  • Decreased urination
  • Irritability or lethargy
  • Intractable vomiting
  • Persistent diarrhea
  • Inability to maintain oral hydration

Dietary Recommendations

Maintaining proper nutrition is essential during diarrheal episodes in pregnancy:

  • Continue normal diet throughout the diarrheal episode 1
  • Recommended foods: Starches, cereals, yogurt, fruits, and vegetables 2, 1
  • Avoid: Foods high in simple sugars and fats, which can worsen diarrhea 2, 1

Medication Considerations

Medication use requires careful consideration during pregnancy:

  • Antimotility agents: Loperamide is contraindicated due to risks of cardiac adverse reactions and potential concerns during pregnancy 3
  • Antibiotics: Only consider when specific indicators are present:
    • Dysentery (bloody diarrhea)
    • High fever
    • Diarrhea lasting >5 days
    • Specific identified pathogen requiring treatment 2, 1

Special Considerations for Pregnancy

Pregnant women at term require additional monitoring:

  • Fluid replacement: More critical due to increased risk of dehydration affecting both mother and fetus
  • Monitoring: Regular assessment of maternal vital signs and fetal well-being
  • Safety data: Limited research on medication use specifically in pregnancy at term 4

When to Seek Immediate Medical Care

Advise patients to seek immediate medical attention if:

  • Signs of moderate to severe dehydration develop
  • Bloody diarrhea occurs
  • High fever develops
  • Persistent vomiting prevents oral rehydration
  • Decreased fetal movement is noted
  • Diarrhea persists beyond 48-72 hours despite management

Prevention Measures

While managing the current episode, prevention of further complications is important:

  • Hand hygiene: Proper handwashing techniques
  • Food safety: Ensure proper food preparation and storage
  • Environmental cleaning: Appropriate cleaning of surfaces to prevent spread 1

The evidence suggests that most cases of acute diarrhea in pregnancy can be managed effectively with oral rehydration and dietary modifications, with careful monitoring for complications that might require more intensive intervention.
