Pregnancy is a beautiful journey marked by exciting milestones and physical changes, but it also comes with its own set of health challenges. Among these, hypertension in pregnancy and pregnancy-induced hypertension (PIH) are increasingly common concerns that every expectant mother should be aware of.
At THT HMO, we are committed to supporting your health throughout pregnancy, not just with physical care, but with clear information and compassionate guidance. Understanding these conditions is the first step in protecting yourself and your baby.
What Is Hypertension in Pregnancy?
Hypertension refers to high blood pressure i.e when the force of blood against the artery (blood vessel) walls is consistently too high. During pregnancy, this can either be a pre-existing condition or develop because of the pregnancy (known as Pregnancy-Induced Hypertension or PIH).
There are three main types:
- Chronic Hypertension: High blood pressure present before pregnancy or before 20 weeks of gestation.
- Gestational Hypertension (PIH): High blood pressure that develops after 20 weeks of pregnancy without signs of organ damage.
- Preeclampsia: A more serious form of hypertension that includes signs of damage to other organs, most often the kidneys or liver. Presenting with protein in the urine and other physical signs.
Let’s Clarify Them?
Gestational hypertension and pregnancy-induced hypertension (PIH) refer to the same condition
Gestational Hypertension / Pregnancy-Induced Hypertension (PIH) is:
- High blood pressure (≥140/90 mmHg) that develops after 20 weeks of pregnancy
- Without protein in the urine (which would indicate preeclampsia)
- In a woman who had normal blood pressure before pregnancy
Key points:
- The terms are used interchangeably in most medical and clinical settings.
- If not properly monitored, gestational hypertension can progress to preeclampsia, a more serious condition.
- It usually resolves after delivery, but it increases the mother's risk for chronic hypertension in the future.
Why Does Hypertension Happen During Pregnancy?
Hypertension during pregnancy can have many causes, often a mix of physical, genetic, and environmental factors:
- Hormonal changes affecting blood vessels
- Increased blood volume to support the growing baby
- Narrow or constricted blood vessels
- Placental development issues
- Pre-existing health conditions (such as obesity, diabetes, or kidney disease)
It’s important to note that not all cases are preventable, but many are manageable with early detection and care.
Who’s at Risk?
Some women are more likely to develop hypertension during pregnancy due to certain risk factors:
- First-time pregnancy
- Age over 35 or under 20
- Family history of hypertension or preeclampsia
- Obesity or being overweight
- Multiple pregnancy (e.g., twins or triplets)
- Pre-existing high blood pressure, diabetes, or kidney disease
- Short or long interval between pregnancies
If you fall into any of these categories, regular monitoring and early care are essential.
What Are the Symptoms to Watch For?
Hypertension often has no symptoms or usually presents late, which is why routine antenatal checkups are crucial. However, if symptoms do appear, they may include:
- Headaches that don’t go away
- Blurred vision or light sensitivity
- Swelling in the hands, face, or legs
- Sudden weight gain
- Shortness of breath
- Upper abdominal pain
- Nausea or vomiting (in severe cases)
Never ignore these signs, especially after 20 weeks of pregnancy.
Is It Dangerous?
Understandably, hearing about hypertension in pregnancy can be scary, but early diagnosis and proper care make a huge difference.
If left unmanaged, hypertension can increase the risk of:
- Preterm birth
- Placental abruption (when the baby's placenta separates from the womb too early before term)
- Low birth weight
- Preeclampsia and eclampsia (a severe complication with seizures)
- Delayed fetal growth
- Cesarean delivery
The good news is most women with hypertension in pregnancy deliver healthy babies with appropriate care and monitoring.
Prevention and Lifestyle Modifications
While not all causes can be prevented, adopting a healthy lifestyle before and during pregnancy significantly reduces your risk:
- Eat a balanced, low-sodium diet: Focus on fruits, vegetables, whole grains, and lean protein.
- Stay active: Light exercises like walking or prenatal yoga help with circulation and weight control (always consult your doctor first).
- Limit salt, caffeine, and processed foods.
- Avoid smoking and alcohol.
- Attend all prenatal appointments for blood pressure monitoring and early detection.
- Manage stress: Deep breathing, rest, and emotional support go a long way.
- Watch your weight gain: Follow your provider’s guidelines for healthy weight progression during pregnancy.
Treatment and Management Options
If you’re diagnosed with PIH or another form of hypertension during pregnancy, don’t panic. Your healthcare team will guide you through safe and effective treatment options:
- Frequent monitoring: Regular checkups to track blood pressure, urine protein, and fetal health.
- Lifestyle adjustments as listed above.
- Medications: Some antihypertensive drugs are safe during pregnancy (your doctor will choose what’s best for you and your baby).
- Hospital observation (admission for observation) in severe cases or if preeclampsia is suspected.
- Early delivery: In some cases, inducing labor may be necessary for your safety and the baby’s.
- Cesarean section may be considered as the safest delivery option for both mother and baby.
What You Can Do as a Mother-to-Be
You play a central role in your health during pregnancy. Here’s what you can do:
- Track your symptoms and speak up during antenatal visits.
- Monitor your blood pressure at home if advised.
- Ask questions, there’s no such thing as too much information when it comes to your baby’s well-being.
- Build a support system of family, friends, and professionals.
- Take your prescribed medications faithfully.
