Beginning signs of pre-eclampsia

Pre-eclampsia is a pregnancy-related condition involving changes in blood pressure and the way organs are working. It can develop after the middle of pregnancy or after birth, and some people feel well while blood pressure or urine testing raises concern. Warning symptoms may include a headache that does not settle, flashing lights or blurred vision, pain beneath the ribs, sudden swelling of the face or hands, nausea, vomiting, or shortness of breath. These symptoms have other causes too, so testing is needed.

Tell your maternity team promptly about any new warning symptom, even if you have an antenatal appointment scheduled later. Attend blood-pressure and urine checks and bring a list of medicines and supplements. Do not take someone else’s blood-pressure medicine or use a home reading to dismiss symptoms. Your team may arrange blood tests, fetal monitoring, or closer review, depending on your findings and stage of pregnancy.

Seek urgent maternity assessment for severe or persistent headache, vision changes, severe pain under the ribs, difficulty breathing, chest pain, a seizure, fainting, or feeling suddenly very unwell. Sudden swelling with other symptoms also needs prompt attention. After birth, these warning signs remain urgent because pre-eclampsia can first appear postpartum. Call emergency services for a seizure, severe breathing difficulty, or collapse.

Ask what your blood-pressure and urine results mean, whether you need blood tests or fetal monitoring, and which symptoms should send you straight to maternity triage. Discuss the follow-up plan, possible timing of birth, and how treatment decisions would change if your condition worsens.
