Possible complications of pre-eclampsia

Pre-eclampsia can worsen quickly, even when blood pressure symptoms are mild. Severe disease may cause a seizure, stroke-like neurological problems, liver injury, reduced kidney function or changes in blood clotting. The placenta may not work well, which can restrict the baby's growth or reduce oxygen delivery. Placental separation and early birth are also possible concerns.

Care teams check blood pressure, urine, blood tests, symptoms and the baby's growth and wellbeing. The condition can occur during pregnancy or after birth, so postnatal warning signs still deserve attention.

Keep every recommended antenatal and postnatal review, take prescribed medicine as directed, and record symptoms such as headache, visual change or upper-abdominal pain. Monitoring may include repeated blood pressure checks, blood tests, urine testing and ultrasound assessment. Depending on gestation and severity, clinicians may recommend observation, medicines, or planning birth by induction or Caesarean Section. An Antenatal Care Package can support regular checks.

Seek urgent maternity assessment for a severe or persistent headache, flashing lights or blurred vision, severe pain beneath the ribs, sudden breathlessness, chest pain, confusion, a seizure, heavy bleeding, or markedly reduced baby movements. Do not wait for a routine appointment if these symptoms appear; call emergency services for collapse, seizure or severe breathing difficulty.

Ask which blood-pressure readings or symptoms should trigger a call, how often your blood and urine will be checked, how the baby's growth is being followed, and what would make early birth safer. Also ask what monitoring is needed after delivery and which medicines are compatible with breastfeeding.
