Preeclampsia affects approximately 8–10% of all pregnancies in India — that's roughly 1 in 12 expecting mothers. It is one of the leading causes of maternal and fetal death in our country, yet many women miss the early signs because they feel completely fine.
The condition is defined by high blood pressure (hypertension) and organ damage during pregnancy, usually after 20 weeks. Left untreated, it can escalate to eclampsia (seizures), HELLP syndrome, or organ failure — all medical emergencies.
The good news: when caught early with regular monitoring, preeclampsia is very manageable. This guide will help you know what to watch for.
What Is Preeclampsia?
Preeclampsia is a pregnancy complication characterised by:
- Blood pressure ≥ 140/90 mmHg on two readings at least 4 hours apart, after 20 weeks of pregnancy
- Protein in the urine (proteinuria) — your urine appears frothy or a dipstick test at the clinic shows 2+ or more
- Or signs of damage to organs such as the liver, kidneys, or brain — even without proteinuria
It is not simply "high blood pressure in pregnancy" — women who had hypertension before pregnancy have chronic hypertension, which is different. Preeclampsia is a new condition that develops during pregnancy and affects multiple organ systems.
Early Warning Signs to Watch For
In mild preeclampsia, many women have no symptoms at all — which is why your doctor checks your blood pressure and urine at every antenatal visit. But some women do notice:
- Headache that does not go away — especially a dull, persistent ache at the front or back of the head that does not respond to paracetamol
- Sudden swelling (oedema) — puffiness in the face, hands, and around the eyes. Some ankle swelling is normal in pregnancy; face and hand swelling is not
- Rapid weight gain — gaining more than 1 kg in a single week, especially in the third trimester, due to fluid retention
- Vision changes — blurring, seeing spots or flashing lights, temporary vision loss, or sensitivity to light
- Pain in the upper right abdomen — under the ribs on the right side, where the liver sits. This can feel like indigestion or a dull ache
- Nausea or vomiting in the third trimester — not first-trimester morning sickness, but new-onset nausea after 20 weeks
- Decreased urination — significantly less urine output than normal, or darker urine
BP reading of 160/110 mmHg or higher — Severe headache that won't go away — Blurred vision or seeing flashing lights — Pain under the ribs on the right side — Difficulty breathing — Seizures or loss of consciousness. These are signs of severe preeclampsia or eclampsia. Call 108 or go to the nearest hospital immediately.
Blood Pressure Reference Guide During Pregnancy
| BP Reading | Classification | Action |
|---|---|---|
| Below 120/80 mmHg | Normal | Continue routine antenatal care |
| 120–129 / below 80 | Elevated | Monitor closely, lifestyle changes |
| 130–139 / 80–89 | Stage 1 Hypertension | Consult your OB-GYN; may need medication |
| 140/90 mmHg or higher | Preeclampsia threshold | Seek medical care immediately |
| 160/110 mmHg or higher | Severe hypertensive crisis | Emergency — go to hospital now |
Log your blood pressure reading after every clinic visit in the Aayi.ai app. Your doctor can see BP trends across visits directly in their dashboard — making it much easier to spot a gradual rise before it becomes a crisis. Ask aayi Companion: "What is a normal BP range during my trimester?"
Who Is at Higher Risk?
You are at higher risk of preeclampsia if you have any of the following:
- First pregnancy (primigravida) — especially with a new partner
- Previous preeclampsia in an earlier pregnancy
- Carrying twins, triplets, or multiples
- Pre-existing conditions: hypertension, diabetes (Type 1, Type 2, or gestational), kidney disease, lupus, or antiphospholipid syndrome
- Obesity (BMI over 30 before pregnancy)
- Age over 35 or under 20
- Family history — your mother or sister had preeclampsia
- IVF pregnancy
If you have multiple risk factors, your OB-GYN may recommend low-dose aspirin (75 mg/day) starting before 16 weeks. This has been shown in large clinical trials to reduce preeclampsia risk by 10–25% in high-risk women. Do not start aspirin without your doctor's advice.
Preeclampsia vs. Normal Pregnancy Symptoms
Some preeclampsia symptoms overlap with normal pregnancy discomfort, making it confusing. Here's how to tell them apart:
- Normal ankle swelling gets better when you elevate your legs and is worse at the end of the day. Preeclampsia swelling also affects the face and hands and does not improve with rest.
- Tension headaches respond to paracetamol and rest. Preeclampsia headaches are persistent and don't improve with standard pain relief.
- Vision changes from screen fatigue resolve with rest. Preeclampsia vision changes — floaters, flashing lights, blurring — are persistent and new.
What Happens If Preeclampsia Is Not Treated?
Untreated preeclampsia can rapidly escalate to:
- Eclampsia — seizures during pregnancy or shortly after delivery, which can cause stroke or death
- HELLP syndrome — Haemolysis, Elevated Liver enzymes, Low Platelets — a severe variant requiring emergency delivery
- Placental abruption — the placenta separating from the uterine wall, causing life-threatening bleeding
- Preterm birth — if the baby must be delivered early to save the mother's life
- IUGR (Intrauterine Growth Restriction) — restricted blood flow to the baby affecting growth
The Aayi.ai app lets you log daily symptoms — headache severity, swelling level, kick count — and flags patterns for your doctor. If your symptom log shows three or more days of worsening headaches, your doctor receives an alert. This kind of early warning is what makes the difference between a managed condition and an emergency.
How Is Preeclampsia Treated in India?
There is currently no cure for preeclampsia except delivery of the baby. Treatment depends on severity and gestational age:
- Mild preeclampsia before 37 weeks: Close monitoring with BP checks 2–3 times per week, urine protein monitoring, fetal movement counts, and growth scans every 2 weeks. Your doctor may admit you to hospital for observation.
- Mild preeclampsia at or after 37 weeks: Induction of labour is usually recommended, as there is no benefit to continuing pregnancy beyond term with preeclampsia.
- Severe preeclampsia: Hospital admission, antihypertensive medication (labetalol, nifedipine, or methyldopa), magnesium sulphate to prevent seizures, and delivery planning — often by 34–37 weeks depending on severity.
- Eclampsia (seizures): Immediate IV magnesium sulphate + emergency delivery.
After delivery, BP usually normalises within 12 weeks. However, women who had preeclampsia have a higher lifelong risk of cardiovascular disease and should have their BP monitored annually.
What You Can Do Right Now
You cannot prevent preeclampsia entirely, but you can catch it early and reduce your risk:
- Attend every scheduled antenatal visit — BP and urine protein are checked at each one
- Invest in a home BP monitor (available at medical stores for ₹800–₹1,500) and log readings twice a day
- Take low-dose aspirin if your doctor has recommended it
- Reduce salt intake and stay well hydrated
- Track your baby's kick count daily after 28 weeks (aim for 10 kicks in 2 hours)
- Never ignore a persistent headache, face swelling, or vision changes during pregnancy
Track blood pressure, symptoms & kick count — all visible to your doctor
