In a postpartum patient 5 days after a lower‑segment Caesarean section with normal blood pressure, presenting with headache, sore throat, palpitations, and insomnia, what evaluation and management is recommended?

Immediate Evaluation for Postpartum Preeclampsia/Eclampsia is Required

This patient requires urgent blood pressure monitoring, urinalysis for proteinuria, and neurological assessment to rule out late postpartum preeclampsia/eclampsia, which can present up to 6 weeks postpartum even without prior hypertension.

Critical Red Flags Present

Your symptom constellation is concerning for late postpartum hypertensive complications:

• Headache at day 5 post-LSCS is a critical warning sign
• Palpitations suggest cardiovascular instability
• Insomnia may indicate sympathetic hyperactivity
• Normal BP in clinic does NOT exclude hypertensive emergency - BP can fluctuate and spike between measurements

Late postpartum eclampsia can occur up to 7 days (or beyond) after delivery in women with completely normal blood pressures throughout pregnancy and the immediate postpartum period 1. Approximately 27% of postpartum hypertensive admissions represent de novo (new onset) hypertension that was not present during pregnancy 2.

Immediate Actions Required

1. Blood Pressure Monitoring

• Check BP immediately - single normal reading is insufficient
• Home BP monitoring should be performed at least once daily for minimum 2 weeks postpartum 3
• Treatment threshold: BP ≥140/90 mmHg requires antihypertensive therapy 3
• Time to presentation for postpartum hypertensive complications averages 3-5 days 2

2. Laboratory Evaluation

• Spot urine protein-to-creatinine ratio (threshold >308 mg/g suggests preeclampsia) 1
• Complete blood count, liver enzymes, creatinine
• Consider lactate dehydrogenase if HELLP syndrome suspected

3. Neurological Assessment

• Fundoscopic examination to evaluate for papilledema 4
• Assess for visual changes, focal deficits, altered consciousness
• Brain imaging (CT or MRI) is indicated if:
  • Nonorthostatic headache present
  • Headache onset >5 days after delivery
  • Focal neurological deficits, visual changes, altered consciousness, or seizures develop 5

Differential Diagnosis Priority

Most Urgent (Rule Out First):

1. Late postpartum preeclampsia/eclampsia - can present without prior hypertension 1
2. Postdural puncture headache (PDPH) - if spinal/epidural anesthesia was used
3. Cerebral venous thrombosis - presents with headache and neurological symptoms 6
4. Idiopathic intracranial hypertension - rare but causes severe headache with visual disturbance 4

Less Urgent:

1. Viral upper respiratory infection (sore throat component)
2. Thyroid dysfunction (postpartum thyroiditis can cause palpitations)
3. Anxiety/postpartum mood disorder

PDPH Considerations

If you received spinal or epidural anesthesia during your LSCS:

• Orthostatic component is key: Does headache worsen when upright and improve when lying flat?
• PDPH typically presents within 5 days of dural puncture 5
• However, brain imaging should be considered when headache onset is >5 days after suspected dural puncture 5
• Non-orthostatic headache or development of non-orthostatic features after initial orthostatic headache warrants imaging 5

Management Algorithm

Step 1: Urgent BP check and repeat measurements

• If BP ≥140/90 mmHg → Start antihypertensive therapy immediately 3
• Continue monitoring at least daily for 2 weeks 3

Step 2: Obtain urine protein-to-creatinine ratio and basic labs

Step 3: If headache is severe, non-orthostatic, or associated with visual changes:

• Perform fundoscopic exam 4
• Obtain brain imaging (CT or MRI) 5

Step 4: If preeclampsia confirmed:

• Initiate or continue antihypertensive therapy
• Consider magnesium sulfate if severe features present 1
• Maintain inpatient monitoring for at least 12 hours after medication adjustment 3

Critical Pitfalls to Avoid

• Do not dismiss symptoms because BP was "normal" at one measurement - nearly 50% of hypertension-related maternal deaths occur postpartum, and 80% are preventable 3
• Do not attribute all symptoms to anxiety or normal postpartum recovery - headache with palpitations warrants investigation
• Do not delay imaging if warning signs present - focal deficits, visual changes, or altered consciousness require immediate neuroimaging 5
• Do not assume absence of antenatal hypertension excludes postpartum preeclampsia - de novo postpartum hypertension accounts for over 25% of cases 2

Regarding the Sore Throat

While the sore throat component suggests possible viral illness, this does not exclude serious postpartum complications. Upper respiratory symptoms can coexist with hypertensive disorders. The combination of headache, palpitations, and insomnia takes priority in risk stratification.

Contact your obstetric provider or go to the emergency department today for evaluation. The 5-day timeframe, symptom constellation, and potential for rapid deterioration warrant same-day assessment rather than waiting for scheduled follow-up.
