What are non-pharmacological (non-medication) methods for managing nausea and vomiting of pregnancy?

Non-Pharmacological Methods for Managing Nausea and Vomiting of Pregnancy

Diet and lifestyle modifications are the initial and most effective non-pharmacological approaches for managing nausea and vomiting of pregnancy, including eating small, frequent, bland meals, avoiding triggering foods, and identifying specific triggers to avoid. 1

Dietary Interventions

• Consume small, frequent meals throughout the day rather than three large meals 1
• Follow the BRAT diet (bananas, rice, applesauce, and toast) which can help reduce symptoms 1
• Focus on high-protein, low-fat meals which may alleviate nausea 1
• Reduce intake of spicy, fatty, acidic, and fried foods which can worsen symptoms 1
• Identify and avoid specific food triggers, particularly those with strong odors 1, 2
• Increase fluid intake between meals rather than during meals 3

Ginger

• Take ginger capsules (250 mg four times daily) which is recommended by the American College of Obstetricians and Gynecologists (ACOG) 1
• Ginger can be consumed in various forms including tea, candies, or capsules 3
• This is one of the most evidence-supported natural remedies for pregnancy-related nausea 1

Vitamin Supplementation

• Vitamin B6 (pyridoxine) at 10-25 mg every 8 hours can help reduce nausea 1
• This intervention is also recommended by ACOG as a first-line non-pharmacological approach 1

Acupressure and Acupuncture

• Acupressure at specific pressure points (particularly P6 point on the wrist) may help reduce nausea severity 1
• Electroacupuncture has shown significant benefits in reducing the number of emesis episodes 1
• Acupressure wristbands are a convenient, non-invasive option that can be used throughout the day 4

Behavioral and Psychological Approaches

• Alternative therapies such as hypnosis and cognitive behavioral therapy can be considered for persistent symptoms 1
• Supportive counseling and validation of symptoms are important components of managing NVP 4
• Rest in a quiet, comfortable environment when experiencing nausea 3

Timing Considerations

• Early intervention with non-pharmacological methods is critical to prevent progression to hyperemesis gravidarum 1, 2
• Most NVP begins at 4-6 weeks, peaks at 8-12 weeks, and typically subsides by week 20 1
• Implementing these strategies at the first sign of symptoms may improve outcomes 3

Assessment Tool

• The Motherisk Pregnancy-Unique Quantification of Emesis (PUQE) score can help quantify severity and guide treatment decisions 1
• Scores ≤6 indicate mild symptoms, 7-12 moderate, and ≥13 severe, which may require additional interventions 1

When to Consider Pharmacological Options

• If non-pharmacological approaches fail to provide adequate relief, pharmacological options should be considered 1
• Persistent symptoms or weight loss >5% of pre-pregnancy weight may indicate progression to hyperemesis gravidarum requiring medical intervention 1
• Early treatment is essential as symptoms become more difficult to control once they progress 5

These non-pharmacological approaches should be tried first before moving to medication options, as they are safe, inexpensive, and have demonstrated effectiveness for many women experiencing nausea and vomiting during pregnancy 3, 4.
