High Blood Pressure During Pregnancy: Symptoms, Risks and When to Seek Medical Care

A blood pressure reading at an antenatal visit takes less than a minute, and it is easy to treat it as routine. It is not. Hypertensive disorders are among the leading causes of serious complications for mothers in India, and the most dangerous of them, preeclampsia, often causes no symptoms until it is well advanced. If you have been told your BP is high, or you are looking for a high blood pressure during pregnancy doctor in Raipur or elsewhere in Chhattisgarh, this guide explains what the numbers mean and what to do next.

What Counts as High Blood Pressure in Pregnancy?

A blood pressure reading has two numbers. The top one (systolic) is the pressure when your heart beats; the bottom one (diastolic) is the pressure between beats. In pregnancy, doctors use these thresholds:

One high reading is not a diagnosis. Anxiety, a rushed walk into the clinic or the wrong cuff size can all push numbers up. That is why the reading is repeated after rest, and why a diagnosis needs two high readings at least four hours apart. A single reading of 160/110 or above is different: it is treated as urgent straight away.

The Four Types of Pregnancy Hypertension

Not all high BP in pregnancy is the same, and the type decides how you are managed.

• Chronic hypertension: high BP that was present before pregnancy or is found before 20 weeks. Many women only discover it at their first antenatal visit.
• Gestational hypertension: new high BP after 20 weeks, with no protein in the urine and no signs of organ strain. It usually settles after delivery, but around a quarter of women with it go on to develop preeclampsia, so it is watched closely.
• Preeclampsia: new high BP after 20 weeks along with protein in the urine or signs that organs such as the kidneys, liver, brain or placenta are under strain.
• Chronic hypertension with superimposed preeclampsia: preeclampsia developing in a woman who already had high BP.

What Is Preeclampsia?

Preeclampsia is a condition that starts in the placenta. For reasons that are still being studied, the blood vessels supplying the placenta do not develop properly early in pregnancy. The struggling placenta then releases substances into the mother's blood that damage the lining of blood vessels throughout her body. High blood pressure is the visible sign, but the real problem is that many organs can be affected at once.

It can progress to serious complications:

• Eclampsia: seizures in a woman with preeclampsia, a medical emergency.
• HELLP syndrome: breakdown of red blood cells, raised liver enzymes and a low platelet count. It can develop quickly, sometimes with only moderately raised BP.
• Placental abruption: the placenta separating from the uterine wall before delivery, causing bleeding and pain.
• Stroke, kidney injury or fluid on the lungs in severe, untreated cases.

The important point is that it can go from mild to severe within days. That is why the monitoring is frequent and why symptoms should never be left until the next appointment.

Symptoms That Need Urgent Attention

Many women with preeclampsia feel completely well, which is exactly why BP and urine checks happen at every visit. When symptoms do appear, these are the ones to act on the same day:

• A severe headache that does not ease with rest or paracetamol
• Blurred vision, flashing lights, spots or sensitivity to light
• Pain just below the ribs on the right side, or in the upper middle abdomen
• Sudden swelling of the face, hands or feet, especially if it appears over a day or two
• Nausea or vomiting in the second half of pregnancy
• Breathlessness, particularly when lying flat
• Passing much less urine than usual
• Reduced baby movements

A seizure, confusion or a severe headache with visual changes means going to hospital immediately. Our guide to warning signs of a high-risk pregnancy covers the other symptoms that should never wait.

Risks for Mother and Baby

For the baby, the main concern is the placenta. Reduced blood flow can slow growth, reduce the amniotic fluid and, if the condition becomes severe, make an early delivery necessary. That is why growth scans and Doppler studies are part of the monitoring.

For the mother, the risks above are the reason for close watching. There is also a longer-term point that is often missed: women who had preeclampsia have a higher lifetime risk of high blood pressure and heart disease. An annual BP check after delivery is worth continuing for life.

Checking Your Blood Pressure at Home Correctly

If you have been diagnosed with high BP, you may be asked to check it at home between visits. A reading is only useful if it is taken properly:

• Use an automatic upper-arm monitor, not a wrist monitor
• Check the cuff fits your arm; a cuff that is too small gives falsely high numbers
• Sit quietly for five minutes first, back supported, feet flat, legs uncrossed
• Rest your arm on a table so the cuff is at heart level
• Do not talk or check your phone during the reading
• Take two readings a minute apart and write both down with the date and time

Agree in advance with your doctor what number should make you call. A common rule is to phone the same day for any reading of 140/90 or above, and to go to hospital for 160/110 or above or for any reading accompanied by symptoms.

Treatment and Delivery Timing

Medicines

Several blood pressure medicines are safe in pregnancy. Labetalol, nifedipine and methyldopa are the ones most commonly used in India. Some BP medicines used outside pregnancy, such as ACE inhibitors, are not safe for the baby, so never continue or start a BP medicine without your obstetrician's advice.

Monitoring

Depending on severity, this means BP checks once or twice a week or more, urine protein testing, blood tests for platelets, liver and kidney function, and growth scans with Doppler studies for the baby.

Protecting against seizures

In severe preeclampsia, magnesium sulphate is given in hospital to prevent eclampsia. It is one of the most effective and well-established treatments in obstetrics.

Delivery: the only cure

Medicines control blood pressure, but only delivering the placenta cures preeclampsia. The timing is a balance between the mother's safety and the baby's maturity:

High BP does not automatically mean a caesarean. Many women with well-controlled hypertension have an induced normal delivery.

After delivery

Preeclampsia can appear or worsen in the first six weeks after birth, most often in the first few days. Keep checking your BP after going home, and report a severe headache or breathlessness straight away.

Can Preeclampsia Be Prevented?

It cannot always be prevented, but the risk can be lowered:

• Low-dose aspirin: for women at high risk, started ideally between 12 and 16 weeks and continued until about 36 weeks. Only take it on prescription, at the dose your doctor gives.
• Calcium supplementation: reduces the risk where dietary calcium is low, which is common in India. Calcium tablets are provided from the second trimester under the national antenatal programme.
• Reaching a healthy weight before pregnancy and staying active during it.
• Controlling existing BP or diabetes before you conceive.
• Never missing an antenatal BP check, even when you feel fine.

Getting Care in Raipur and Across Chhattisgarh

Preeclampsia treatment in Raipur is available at several tertiary centres, and the most important decision is simply not to delay. What matters in any hospital you choose is that it can monitor you closely, give magnesium sulphate, perform an emergency caesarean at any hour and care for an early baby on site.

Dr. Ankita Bansal Goyal (MD, FMAS, PGIMER Chandigarh) manages hypertension in pregnancy and preeclampsia as part of high-risk pregnancy care at Sankalp Hospital, Bilaspur Road, Ambikapur, for mothers across Chhattisgarh. If you are searching for a pregnancy specialist near me in Surguja, Surajpur, Balrampur or Jashpur, the clinic is open Monday to Saturday, 9:00 AM to 5:00 PM, with obstetric emergencies attended round the clock.
