Pre-eclampsia warning signs: get same-day help
Contact your maternity unit or midwife immediately, today, if you are past 20 weeks of pregnancy (or in the weeks after birth) and you have any of:
- a severe headache that does not settle with paracetamol;
- problems with your vision: blurring, flashing lights, spots or floaters;
- pain just below the ribs, especially on the right side;
- sudden swelling of your face, hands or feet;
- vomiting in the second half of pregnancy, or feeling suddenly and generally unwell;
- a blood pressure reading of 160/110 or higher, even if you feel completely well.[1]
If your baby’s movements slow, change or stop, contact your maternity unit straight away. Call 112 if you have a seizure, severe chest pain, severe breathlessness, sudden weakness or confusion, or someone with you cannot be woken. These warning signs still count in the days and weeks after birth: pre-eclampsia can appear for the first time after delivery.[1]
- Treated online: Assessment online; this condition usually needs in-person or urgent care.
- Pre-eclampsia warning signs (severe headache, vision changes, pain under the ribs, sudden swelling) need same-day maternity assessment, never an online appointment; blood pressure medicines in pregnancy are changed only with your maternity team.
- High blood pressure in pregnancy means readings of 140/90 or above; 160/110 or higher needs same-day assessment even if well.
- Blood pressure often peaks a few days after birth, and pre-eclampsia can appear for the first time after delivery.
- Call 112 if you have a seizure, severe chest pain, severe breathlessness, sudden weakness or confusion, or someone with you cannot be woken.
An online consultation is for understanding readings, getting home monitoring right, and preparing questions, never for anything on the warning list above, and never for a reading of 160/110 or higher, which needs same-day assessment. Blood pressure medicines in pregnancy are started, changed and stopped with your maternity team, not over video.
What counts as high blood pressure in pregnancy?
High blood pressure in pregnancy means a reading of 140/90 mmHg or higher. It covers chronic hypertension (present before pregnancy or before 20 weeks), gestational hypertension (new after 20 weeks), and pre-eclampsia, where high blood pressure comes with signs that organs are affected, classically protein in the urine.[1] Definitions are broadly consistent across Europe, but monitoring pathways and treatment choices vary by country, and maternity teams lead the care.
How an online consultation helps with high blood pressure in pregnancy
- Understand your numbers: what 140/90 means, why 160/110 is a same-day number, why one reading is never a diagnosis, and what your own pattern suggests, explained without jargon.
- Home monitoring done properly: the right cuff, the right technique and a readable log turn scattered numbers into something your midwife can act on. The doctor sets this up with you in one call.
- Medication questions answered honestly: which blood pressure medicines are used in pregnancy, why some must be switched, and why nothing gets stopped or started without your maternity team. Clarity, not tinkering.
- Escalation without delay: if anything in your story belongs in the same-day category, the doctor names it, tells you exactly who to contact today, and does not let a video call stand in for the assessment you actually need.
What the doctor checks in an online blood pressure consultation during pregnancy
The consultation is structured around one question: is this safe to monitor, or does it need assessment now? The doctor will typically check:
- Your readings and your device: the actual numbers, when and how they were taken, whether your monitor is an upper-arm model and the cuff fits, because technique problems masquerade as hypertension.
- Warning symptoms, one by one: headache, vision changes, pain under the ribs, sudden swelling, vomiting, and how your baby has been moving. These questions come first, every time.[1]
- How many weeks pregnant you are: the same reading means different things at 12 weeks (likely chronic hypertension) and at 34 weeks (possible pre-eclampsia).
- Your risk profile: a first pregnancy, age 40 or over, more than ten years since your last baby, a high BMI, a family or personal history of pre-eclampsia, a multiple pregnancy, or existing diabetes, kidney disease or hypertension. Risk factors decide whether low-dose aspirin from 12 weeks should have been discussed, a maternity-team decision worth raising at your next visit.[1]
- Current medicines: everything you take, particularly if you were on blood pressure tablets before conceiving, because some (notably ACE inhibitors and ARBs) are not used in pregnancy and are switched promptly, in a planned way, by your doctors.[2]
- Your monitoring set-up: who is checking your blood pressure and urine, how often, and whether that matches guidance for your situation, so gaps get closed rather than discovered later.
Why does blood pressure matter so much in pregnancy?
Because of pre-eclampsia. It is a condition unique to pregnancy, rooted in the placenta, and it can progress from silent to serious quickly: for the mother, towards seizures (eclampsia), stroke, and liver and clotting problems; for the baby, towards restricted growth and early delivery.[2][4] It affects a minority of pregnancies, most of which end well, and the entire logic of antenatal care (the repeated blood pressure checks, the urine dips) exists to catch it early. The only cure is delivery of the baby and placenta; everything before that is control and timing, decided by specialists weighing mother and baby together. That is why this page keeps repeating the same instruction: warning signs go to the maternity unit today, not to any online service.
Chronic, gestational, pre-eclampsia: three different situations
Chronic hypertension exists before pregnancy and needs its medicines reviewed, ideally before conception. Gestational hypertension appears after 20 weeks without organ signs; it needs closer monitoring because a proportion of women go on to develop pre-eclampsia. Pre-eclampsia itself is high blood pressure plus evidence the body is reacting: protein in the urine, blood test changes, or symptoms from the warning list.[1] The labels matter because they set the monitoring intensity, and because women with any of them benefit from knowing exactly which one applies. If yours has never been named clearly, that is a fair question for one consultation.
After the birth
Blood pressure does not clock off at delivery. It often peaks a few days after birth, gestational hypertension can take weeks to settle, and pre-eclampsia can first appear postpartum.[1] Keep any agreed monitoring going, keep taking prescribed tablets unless told otherwise, and treat the warning list as live for the first weeks after birth. High blood pressure in pregnancy also marks a higher long-term cardiovascular risk, which makes ongoing blood pressure checks in later life genuinely worthwhile.[3][5]
How should I check my blood pressure at home when pregnant?
Use a validated upper-arm monitor with a cuff that fits, sit rested for five minutes with your back supported and arm at heart level, take two readings a minute or two apart, and record both numbers with the date and time. Share the log with your midwife, and agree in advance which numbers mean call today.[2] One honest limit: an online doctor cannot measure your blood pressure through a screen. The value of the consultation is making your own measurements trustworthy and correctly acted on. A single high reading is a prompt to recheck and tell your midwife, not a diagnosis; 160/110 or higher is a same-day number every time.
Can you take blood pressure medicine while pregnant?
Yes. Several blood pressure medicines are used in pregnancy with long experience behind them, commonly labetalol, nifedipine or methyldopa, chosen case by case by maternity teams.[1] Two rules protect you. First, never stop or change a blood pressure tablet on your own: untreated severe hypertension is dangerous in pregnancy. Second, if you conceived while taking an ACE inhibitor or ARB, contact a doctor promptly (within days, not months) to have it switched in a planned way; do not simply abandon treatment.[2] Prescribing rules vary by country, and in pregnancy these decisions sit with your obstetric team; an online doctor explains, checks your understanding, and gets the referral moving.

| Presentation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Home readings creeping up, below 140/90, no symptoms | Check technique, keep a log, mention at next antenatal visit | Yes, for advice and monitoring set-up | If readings reach 140/90, or any warning symptom appears |
| Confirmed readings 140/90 to 159/109, no warning symptoms | Prompt maternity review for assessment, urine check and monitoring plan | Advice and routing only | Within days, via midwife or maternity unit[1] |
| Reading 160/110 or higher, or any pre-eclampsia warning sign | Same-day maternity assessment | No | Today; 112 for seizure, severe chest pain or breathlessness[1] |
| Chronic hypertension, planning pregnancy or newly pregnant on an ACE inhibitor or ARB | Prompt planned medication review, specialist-led | Explanation and urgent routing | Within days of a positive test; pre-conception review is the ideal[2] |
| High readings in the days or weeks after birth | Prompt review; continue prescribed treatment meanwhile | Advice and routing | Same day if 160/110 or higher, or any warning symptom |
Availability of individual medicines and who may prescribe them vary by country; your doctor confirms what applies where you are.

What you can do yourself
Keep every antenatal appointment, because the checks are the safety net. Measure at home properly if asked to, and write readings down rather than trusting memory. Stay active in ways that feel right, eat normally rather than crash-restricting salt, and do not take up new supplements on the promise of lowering blood pressure. Know the warning list on this page well enough to recite it, and make sure whoever is around you late in pregnancy knows it too. What self-care cannot do is treat pre-eclampsia; no diet, tea or rest cures it, and believing otherwise costs time that matters.
Prescription treatment
When treatment is needed, maternity teams use blood pressure medicines with an established place in pregnancy, adjusted to keep readings in a safe range for you and your baby, alongside scheduled blood tests, urine checks and growth scans.[1] Low-dose aspirin from 12 weeks is offered to women at higher risk of pre-eclampsia, a decision made with your maternity team rather than something to self-start.[1] The online role is deliberately modest: explaining the plan you have, catching the readings that need escalating, and never adjusting pregnancy blood pressure treatment by video.
When we help with high blood pressure online, and when we refer you
We help online: making sense of home readings and what to do next; setting up correct home monitoring; explaining a diagnosis of chronic or gestational hypertension or pre-eclampsia risk in plain language; medication questions, including what to do if you conceived on tablets that need switching; and preparing for maternity appointments so the right things get asked.
We refer or redirect you: anyone with a warning-list symptom or a reading of 160/110 or higher, to same-day maternity assessment, including mid-consultation; confirmed new readings of 140/90 or above, to prompt maternity review; anyone whose baby is moving less, to the maternity unit today; medication starts, stops and changes, to the obstetric team; and pre-conception blood pressure reviews, to a doctor who can plan the switch before pregnancy begins. Raised blood pressure also travels with other symptoms worth knowing about, from palpitations and heart symptoms in pregnancy to ordinary ankle swelling from varicose veins, which is gradual and both-sided, unlike the sudden face and hand swelling of pre-eclampsia. Both sit within the pregnancy conditions our doctors assess online.

Frequently asked questions about high blood pressure in pregnancy
Can an online doctor treat pre-eclampsia?
No, pre-eclampsia cannot be treated online, and you should be wary of anyone who claims otherwise. Pre-eclampsia needs in-person maternity assessment: blood pressure measurement, urine testing, blood tests and monitoring of your baby. What an online doctor does is recognise the warning signs fast, tell you exactly where to go today, and help you understand and follow the plan your maternity team sets.
How much does an online consultation cost?
The exact price of a video consultation is shown before payment, and there is no subscription. If the doctor can’t help you online, you get a full refund and clear directions to the right care.
What blood pressure is too high in pregnancy?
140/90 mmHg or higher counts as high in pregnancy and needs prompt maternity review. 160/110 or higher is a same-day number: contact your maternity unit immediately even if you feel well. Below those thresholds, a rising trend is still worth logging and mentioning, because the pattern matters as much as any single reading.
What are the first signs of pre-eclampsia?
Often there are none you can feel, which is why blood pressure and urine are checked at every antenatal visit. When symptoms do appear, the classic ones are severe headache, vision changes such as blurring or flashing lights, pain just under the ribs, sudden swelling of the face, hands or feet, vomiting later in pregnancy, and simply feeling suddenly unwell. Any of them means same-day maternity assessment.
Can I keep taking my blood pressure tablets now I am pregnant?
Do not stop them on your own, and do not panic. Some blood pressure medicines are used routinely in pregnancy; others, such as ACE inhibitors and ARBs, are switched promptly once pregnancy is confirmed. The safe move is a medication review within days: a doctor confirms what you take and arranges the right switch in a planned way.
Does high blood pressure in pregnancy go away after birth?
Usually, if it was gestational: readings typically settle over days to weeks, though they often peak briefly a few days after delivery. Chronic hypertension continues and needs ongoing care. Either way, keep monitoring as advised after birth, because pre-eclampsia can appear postpartum, and have your blood pressure checked in the longer term, since hypertension in pregnancy flags a higher lifetime cardiovascular risk.
How quickly can I speak to a doctor?
Appointments are available daily from 7am to 11pm, often within about 15 minutes, from anywhere in Europe. Use that speed for questions, readings and monitoring plans. Never use it instead of same-day maternity assessment for warning signs or a reading of 160/110 or higher.
Can I check my own blood pressure at home during pregnancy, and what numbers matter?
Yes, home monitoring with a validated upper-arm cuff is genuinely useful in pregnancy, seated, rested and same-time-of-day. The doctor helps you set personal thresholds, but broad rules hold: readings creeping to 140/90 or above deserve prompt review, and 160/110 or above means urgent same-day assessment, no negotiation. Just as important, numbers are not the whole story: severe headache, vision changes, pain under the ribs or sudden swelling override a normal reading every time, because pre-eclampsia can move faster than a cuff.
