How to Recognize High Blood Pressure During Pregnancy

 High blood pressure during pregnancy is more common than most women realize—and often, it can develop quietly without any obvious symptoms. But the good news is that when detected early, it can be managed safely. Understanding the warning signs can protect both you and your baby, ensuring a smooth and healthy pregnancy journey.

Whether you are a first-time mom or expecting again, being aware of changes in your body is the first step toward staying safe. This blog will help you understand what high blood pressure in pregnancy looks like, why it happens, and when you should seek help.

Isha Women’s Hospital, the best maternity center of Dombivli, believes that every mother deserves safe, confident, and informed pregnancy care. Under the expert guidance of Dr Chinmay Pataki, one of the most trusted obstetricians and high-risk pregnancy specialists, thousands of mothers have experienced healthy, well-monitored pregnancies.

By learning to recognize early symptoms—and by staying consistent with your antenatal checkups—you can take control of your health and give your baby the best possible start.

High blood pressure—also called hypertension—means the pressure of blood flowing through your blood vessels is higher than normal.
During pregnancy, a reading of 140/90 mmHg or above is considered high and requires attention.

Many women feel perfectly normal even with high BP, which is why it is sometimes called a “silent condition.” But when left untreated, it can affect blood flow to the placenta, your baby’s growth, and your own health.

High BP during pregnancy can appear in two ways:

• Before pregnancy or before 20 weeks → called chronic hypertension
• After 20 weeks of pregnancy → called gestational hypertension

At Isha Women’s Hospital, Dombivali, Dr Chinmay Pataki, a highly skilled & best fertility and pregnancy specialist, closely monitors every expectant mother to detect these issues early and ensure a safe pregnancy journey. His evidence-based care and advanced antenatal monitoring systems make Isha Women Hospital one of the safest and most trusted maternity centres in Thane and Dombivli.

Understanding the types of high BP helps you identify why regular checkups are so important. Here are the main conditions explained simply:

These conditions are scary to read about, but with timely diagnosis, proper monitoring, and expert care, they can be managed safely.
That’s why mums-to-be at Isha Women’s Hospital benefit from frequent BP checks, advanced fetal monitoring, and round-the-clock specialist support from Dr Chinmay Pataki, one of the most trusted obstetricians and fertility experts in the region.

Some women are more likely to develop high blood pressure during pregnancy. Knowing your risk helps you stay prepared and get extra monitoring when needed.

Common Risk Factors Include:

• Age over 35 years: BP naturally tends to rise with age, making older mothers slightly more prone.
• First pregnancy: Hypertension is more common in first-time mothers.
• Family history of hypertension or preeclampsia
• Obesity or being overweight: Excess weight increases the load on your heart and blood vessels.
• Multiple pregnancy (twins or triplets): The body works harder to support more than one baby.
• Pre-existing conditions like:
  • PCOS (Polycystic Ovary Syndrome)
  • Diabetes
  • Kidney disorders
  • Autoimmune disorders

If you fall into any of these categories, don’t worry — it simply means you need more regular checkups and careful monitoring.

This is exactly where Isha Women’s Hospital excels.

Recognizing the early signs of high blood pressure can help protect both you and your baby. Some symptoms are mild, some are serious, and some may not appear at all. Understanding what to look for—and when to seek help—can make a big difference in preventing complications like preeclampsia.

High blood pressure during pregnancy can show up in several ways. Pay close attention to any of these symptoms, especially if they appear suddenly.

• Persistent Severe Headaches: A throbbing headache that doesn't improve with rest, hydration, or medication may indicate rising blood pressure.
• Blurred or Double Vision: Seeing spots, flashes of light, or blurry vision is a warning sign that your blood pressure may be affecting your eyes and brain.
• Swelling in Hands, Feet, or Face: Some swelling is normal in pregnancy—but sudden, excessive, or facial swelling is not. It suggests fluid retention linked to high BP.
• Sudden Weight Gain: Gaining more than 1–2 kg in a week can indicate fluid buildup, especially in late pregnancy.
• Pain in the Upper Right Abdomen: Sharp or persistent pain under the ribs on the right side can signal liver involvement, often seen in preeclampsia.
• Shortness of Breath: High blood pressure can cause fluid to build in the lungs, leading to difficulty breathing.
• Nausea or Vomiting in Late Pregnancy: Morning sickness usually fades after the first trimester. If nausea returns later, it may be related to high BP or preeclampsia.

Understanding the severity helps you decide when to seek help:

Mild Signs (may be early indicators)

• Mild headache
• Slight swelling in feet
• Feeling unusually tired
• Slightly elevated BP readings

Heavy Signs (need immediate attention)

• Swelling in the face or hands
• Persistent headache
• Blurred vision
• Sudden weight gain
• Upper abdominal pain

 Emergency Signs (seek help immediately)

• Severe headache not improving
• Vision loss or seeing flashing lights
• Severe shortness of breath
• Seizures
• Chest pain
• Very high BP: ≥160/110 mmHg

At Isha Women’s Hospital, these signs are taken very seriously.

Home monitoring gives you confidence and helps catch changes early. Here’s how to do it correctly:

Use a Digital BP Monitor:  Choose a reliable upper-arm monitor (avoid wrist monitors for pregnancy).

Check at the Same Time Daily: Best times:

• Morning before breakfast
• Evening before bed

Sit Properly:

• Sit upright
• Keep feet flat on the floor
• Rest your arm on a table
• Stay calm for 5 minutes before checking

Keep a BP Diary: Record:

• Date
• Time
• Blood pressure reading
• Any symptoms
  This helps your doctor track patterns more accurately.

When to Call Your Doctor: Contact your doctor or visit the hospital if:

• BP is 140/90 mmHg or above on two readings
• BP is 160/110 mmHg or above even once
• You have severe symptoms (headache, vision changes, swelling)
• You feel reduced baby movements
• You simply feel “something is not right”

At Isha Women’s Hospital, patients are encouraged to share their BP diaries during visits. Dr Chinmay Pataki reviews each reading carefully and guides mothers on whether medication, monitoring, or further evaluation is needed.

Understanding why high blood pressure happens during pregnancy can help you stay alert and make healthier choices. While some causes are unavoidable—like genetics—many others can be managed with proper care, diet, and regular follow-ups.

What Causes High Blood Pressure During Pregnancy?

High BP in pregnancy rarely has one single cause. It develops due to a mix of genetic, hormonal, and lifestyle factors, along with how your placenta develops.

• Genetics: If your mother or sister had high blood pressure or preeclampsia, your chances increase. This is because BP regulation can run in families.
• Hormonal Changes: Pregnancy brings major hormonal shifts that affect blood vessel relaxation and fluid balance. In some women, these hormonal changes lead to elevated BP.
• Placental Issues: Sometimes the placenta doesn’t develop normal blood vessels, reducing oxygen supply. This can trigger the body to raise blood pressure as a compensatory response.
• Preexisting Medical Conditions: Conditions like diabetes, PCOS, thyroid disorders, or kidney disease increase the risk of pregnancy-related hypertension.
• Poor Diet or Lifestyle Habits: High salt intake, stress, lack of physical activity, smoking, and being overweight can contribute to rising blood pressure.

At Isha Women’s Hospital, the best maternity care center, Dr. Chinmay Pataki carefully evaluates all these factors during antenatal visits to ensure early detection and safe pregnancy care.
