The short explanation
A single raised reading does not mean you have pre-eclampsia. Blood pressure can be high for many reasons on the day, including rushing to the clinic or anxiety. A repeat check and a urine test for protein, as your doctor has arranged, are the right way to find out. If BP stays high without protein, it may be called gestational hypertension; if protein or certain other signs appear, it may be pre-eclampsia. Either way, the condition is usually managed with closer monitoring of you and the baby, and sometimes treatment to lower BP. Doctors plan the timing of delivery depending on how things progress.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Your risk is higher in a first pregnancy, with twins, high BP or kidney disease before pregnancy, diabetes, or a family history of pre-eclampsia.
- Checking BP at home with a validated machine can help, if your doctor suggests it.
- Pre-eclampsia can develop quickly, so knowing the warning signs between visits is important.
- PHCs and sub-centres can check BP if your hospital is far away.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether you have pre-eclampsia. Only repeat BP checks, urine and blood tests, and your doctor's assessment can show that.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is my BP high enough to need treatment?
- What did the urine protein test show?
- How often should my BP be checked from now on?
- Which symptoms should make me come in straight away?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you have a severe headache, blurred vision or flashing lights, pain under the ribs, sudden swelling of the face or hands, fits, or breathlessness.
Get help the same day
- Get care the same day if a home BP reading is much higher than at the clinic, or if the baby moves less.
Book an appointment soon
- Attend the repeat BP and urine check within the two days your doctor gave.
Raise it at a routine appointment
- Keep all routine antenatal appointments; BP is checked at each one.
