Understanding Gestational Hypertension and Preeclampsia: Recognising Warning Signs and Keeping Blood Pressure Under Control
While pregnancy is one of the most exciting and transformative times in a woman’s life, it also brings a host of changes, some expected and others not so much. One change that can take many women by surprise is an increase in blood pressure, a condition medically referred to as gestational hypertension. In some cases, this can escalate into a more serious condition known as preeclampsia.
In this article, we’ll explore what gestational hypertension and preeclampsia are, how to recognise the warning signs and what steps you can take to keep your blood pressure under control for a healthier pregnancy.
What Is Gestational Hypertension?
Gestational hypertension is high blood pressure that develops after 20 weeks of pregnancy in women who previously had normal blood pressure. Unlike chronic hypertension, which exists before pregnancy or is diagnosed before 20 weeks, gestational hypertension is specific to pregnancy.
Fortunately, it often resolves after delivery. However, it’s essential to monitor it closely as it can lead to more serious complications, including preeclampsia.
What Is Preeclampsia?
Preeclampsia is a condition that typically occurs after 20 weeks of pregnancy and is characterised by high blood pressure along with signs of organ damage, most commonly to the liver and kidneys. Left untreated, preeclampsia can lead to severe complications for both the mother and the baby, including eclampsia, which involves seizures.
While preeclampsia sounds alarming, early detection and management significantly reduce risks. That’s why understanding its symptoms is critical.
Warning Signs to Look Out For
Recognising symptoms early can be lifesaving. Common warning signs include:
Swelling (Oedema): Sudden swelling in the face, hands or feet that doesn’t subside with rest.
Severe Headaches: Persistent headaches that don’t respond to usual remedies.
Vision Problems: Blurred vision, flashing lights or sensitivity to light.
Upper Abdominal Pain: Pain, especially under the ribs on the right side.
Nausea or Vomiting: Persistent nausea or vomiting after the first trimester.
Shortness of Breath: Difficulty breathing without exertion.
Sudden Weight Gain: Rapid weight gain due to fluid retention.
High Blood Pressure Readings: Regular readings above 140/90 mmHg.
If you experience any of these symptoms, contact your healthcare provider immediately.
Risk Factors for Gestational Hypertension and Preeclampsia
Certain factors can increase your risk, including:
First Pregnancy: Women in their first pregnancy are more prone.
Age: Being younger than 20 or older than 40.
Obesity: BMI > 30 before pregnancy can increase risks.
Family History: A family history of preeclampsia or hypertension.
Multiple Pregnancies: Carrying twins, triplets, or more.
Pre-existing Conditions: Conditions like diabetes, kidney disease, or chronic hypertension.
Knowing your risk factors allows for early planning and monitoring.
How to Keep Blood Pressure Under Control During Pregnancy
Managing your blood pressure is key to preventing complications. Here are some practical steps:
1. Regular Prenatal Check-ups:
o Attend all antenatal appointments to track your blood pressure and overall health.
2. Maintain a Healthy Diet:
o Focus on a balanced diet rich in fruits, vegetables, and whole grains.
o Reduce salt intake, which can lead to fluid retention and higher blood pressure.
3. Stay Active:
o Engage in gentle exercises like walking, swimming, or prenatal yoga to improve circulation.
4. Manage Stress:
o Practice relaxation techniques such as deep breathing, meditation, or prenatal massage.
5. Monitor Your Weight:
o Gain weight gradually, as excessive weight gain can increase risks.
6. Take Prescribed Medications:
o If your doctor prescribes medication, take it exactly as instructed.
7. Rest Adequately:
o Elevate your feet when resting to reduce swelling and improve circulation.
8. Avoid Harmful Substances:
o Steer clear of smoking, alcohol and recreational drugs as they will significantly raise your risk of developing hypertension.
9. Educate Yourself:
o Stay informed about symptoms and warning signs so you can act quickly if something changes.
Treatment Options
If gestational hypertension or preeclampsia is diagnosed, treatment may involve:
Medications: Blood pressure medications that are safe during pregnancy.
Monitoring: Frequent blood pressure checks and urine tests to monitor protein levels.
Early Delivery: In severe cases, delivery may be recommended to prevent complications.
Your healthcare provider will tailor the treatment plan based on the severity of your condition.
Breastfeeding with Hypertension or Preeclampsia
Breastfeeding is highly encouraged for mothers with a history of hypertension or preeclampsia, as it offers numerous health benefits for both the baby and the mother.
Breastfeeding can help lower blood pressure and support postpartum recovery due to the release of oxytocin, a hormone that promotes relaxation and reduces stress. For mothers with preeclampsia, breastfeeding may also contribute to hormonal balance and weight management, aiding in the recovery process.
However, there are important considerations to ensure a smooth breastfeeding journey. Mothers who require antihypertensive medications should consult their healthcare provider to confirm that their prescribed drugs are safe for breastfeeding. Many blood pressure medications, such as labetalol and nifedipine, are compatible with breastfeeding, but some may require adjustments to avoid affecting the baby.
Staying hydrated is crucial, as dehydration can worsen blood pressure fluctuations. Maintaining a balanced diet rich in nutrients also supports milk production and overall health. Mothers should prioritise rest and stress management techniques, such as meditation or gentle yoga, to create a calm environment that fosters successful breastfeeding.
Regular monitoring of blood pressure and follow-up appointments with healthcare providers are essential to ensure stability and address any concerns promptly. If breastfeeding becomes challenging, lactation consultants can offer support and practical strategies to help mothers establish and maintain breastfeeding.
While preeclampsia may feel overwhelming, breastfeeding can provide a sense of empowerment and bonding, promoting both physical and emotional well-being during the postpartum period.
Postpartum Recovery
For most women, their blood pressure normalises after delivery. However, some may continue to experience high blood pressure or require medication for a few weeks or months. Follow-up appointments are crucial to ensure a full recovery.
It’s also important to adopt a healthy postpartum lifestyle. Continue eating well, staying active and monitoring blood pressure regularly to reduce the risk of long-term complications.
Pregnancy is a journey filled with excitement, hope, and sometimes, unexpected hurdles. Gestational hypertension and preeclampsia can seem daunting, but with early detection, regular monitoring and proactive care, most women go on to have healthy pregnancies and babies.
Listen to your body, prioritise regular check-ups and never hesitate to reach out to your healthcare provider if something feels off. Remember, knowledge is power and in this case, it’s also peace of mind.
Stay healthy, stay informed and enjoy the beautiful journey of motherhood!
