Reduced/change in fetal movements
👶 Fetal movements are a reassuring sign of fetal well-being. Most women notice them from around 18–20 weeks, with movements becoming stronger and more regular as pregnancy progresses. 🚨 A noticeable reduction or change in fetal movements may indicate potential fetal distress or complications, requiring prompt evaluation.
✅ What is Considered Normal?
- 🤰 Most women first feel movements between 18–24 weeks (earlier in multiparous women).
- 📈 By the third trimester (after 28 weeks), movements become more regular and easier to track.
- 🔄 Movements increase in frequency and strength until ~32 weeks, then plateau but should not reduce.
- 🦶 Normal movements include kicks, rolls, swishes, and turns.
⚠️ Causes of Reduced / Changed Movements
- 💤 Fetal sleep cycles: Quiet phases lasting 20–40 minutes (up to 90 minutes).
- 🩸 Placental insufficiency: Reduced oxygen/nutrient delivery to the fetus.
- 💧 Oligohydramnios: Low amniotic fluid restricting movement.
- ⛔ Fetal hypoxia/distress: Decreased activity due to impaired oxygenation.
- 👩 Maternal factors: Stress, dehydration, smoking, sedative drugs.
- 🧬 Fetal abnormalities: Congenital or chromosomal disorders may reduce activity.
🔍 Assessment of Reduced Fetal Movements
- 📖 History: Ask about frequency, pattern, and quality of movements + associated symptoms (bleeding, pain).
- 🩺 Examination: Assess maternal well-being, uterine size, and abdominal tenderness.
- 💓 Fetal heart rate monitoring: Doppler or CTG to detect abnormalities.
- 🖥️ Ultrasound: Assess growth, amniotic fluid, and placental function (consider Doppler studies).
🛠️ Management
- 🤱 Reassurance: If movements are normal after assessment, reassure and advise ongoing monitoring.
- 🧪 Further investigations: If concerns persist → growth scans, Doppler, serial CTGs.
- 👶 Early delivery: Indicated if evidence of fetal distress or severe growth restriction.
- 📊 Maternal education: Teach "count to 10" method (expect 10 movements in 2 hours after 28 weeks). Emphasise seeking help if concerned.
🚨 Red Flags (Require Urgent Action)
- ⬇️ Sudden or marked reduction in movements after 28 weeks.
- 🕛 No movements felt for >12 hours in the third trimester.
- ⚡ Movements that are weaker or markedly different in pattern.
- 🚩 Associated warning signs: vaginal bleeding, abdominal pain, fluid leakage.
👩⚕️ Key Considerations for Clinicians
- 🔎 Always take maternal concerns seriously-delayed action can lead to stillbirth.
- 📘 Follow NICE & RCOG guidelines on reduced fetal movements.
- 🤝 Involve multidisciplinary teams (obstetricians, midwives, fetal medicine if needed).
- 📝 Document history, examination, investigations, and advice thoroughly.
