Pregnancy is an important stage of life that requires regular medical care and monitoring. One condition that deserves special attention is preeclampsia during pregnancy, a pregnancy-related complication associated with high blood pressure. It usually develops after 20 weeks of pregnancy and can affect the health of both mother and baby.
Some women may not experience noticeable symptoms in the early stages. Regular antenatal check-ups therefore play an important role in identifying high blood pressure and other possible warning signs early.
If you are searching for information about preeclampsia symptoms, causes, risk factors, treatment, or high blood pressure during pregnancy, this guide explains the important points every expectant mother should know.
What Is Preeclampsia During Pregnancy?
Preeclampsia is a pregnancy complication involving high blood pressure that generally develops after 20 weeks of pregnancy. It may also involve protein in the urine or signs that organs such as the kidneys, liver, blood or brain are being affected.
The condition can range from mild to severe. In some cases, it can progress to eclampsia, which may cause seizures and requires urgent medical treatment.
Regular prenatal visits are important because a pregnant woman may have high blood pressure without feeling unwell.
What Are the Symptoms of Preeclampsia?
Recognizing the signs of preeclampsia can help pregnant women seek medical attention at the right time. Some symptoms may be mild, while others require urgent evaluation.
Common warning signs include:
1. High Blood Pressure
A blood pressure reading of 140/90 mmHg or higher after 20 weeks of pregnancy requires medical assessment. Your doctor may recommend repeat measurements and additional tests.
2. Severe or Persistent Headache
A headache that continues despite rest or usual measures should not be ignored. Persistent headaches can sometimes occur with pregnancy-related high blood pressure.
3. Vision Changes
Changes in vision can include:
- Blurred vision
- Seeing spots
- Flashing lights
- Temporary loss of vision
- Increased sensitivity to light
Such symptoms should be reported to your obstetrician promptly.
4. Sudden Swelling
Some swelling of the feet and ankles is common during pregnancy. However, sudden or significant swelling involving the face or hands should be discussed with your doctor, especially when other symptoms are present.
5. Upper Abdominal Pain
Pain below the ribs or in the upper-right area of the abdomen can sometimes indicate complications involving the liver.
6. Shortness of Breath
Difficulty breathing can be a concerning symptom, particularly when it develops suddenly or occurs together with other warning signs.
7. Nausea or Vomiting
New or severe nausea and vomiting later in pregnancy may require medical assessment when accompanied by headache, abdominal pain or other symptoms.
What Causes Preeclampsia?
The exact cause of preeclampsia is not completely understood. Researchers believe that abnormal development and functioning of the placenta and its blood vessels may contribute to the condition.
Several factors can affect how blood flows between the mother and placenta. These changes may contribute to high blood pressure and problems involving other organs.
Importantly, preeclampsia is not caused simply by stress or by something a pregnant woman has done wrong.
Who Is at Higher Risk of Preeclampsia?
Certain factors can increase the possibility of developing pregnancy-related hypertension or preeclampsia.
Women may have a higher risk if they have:
- A previous history of preeclampsia
- A first pregnancy
- Twin or multiple pregnancy
- Chronic high blood pressure
- Diabetes
- Kidney disease
- Certain autoimmune conditions
- A family history of preeclampsia
- Obesity
- Maternal age of 35 years or older
- Pregnancy following IVF
Having a risk factor does not necessarily mean that preeclampsia will develop. Nevertheless, women with higher-risk pregnancies may benefit from closer antenatal monitoring.
Can Preeclampsia Affect the Baby?
Yes. Severe pregnancy-related high blood pressure can affect the placenta and the supply of oxygen and nutrients to the baby.
Possible complications include:
- Restricted fetal growth
- Preterm birth
- Placental abruption
- Low birth weight
- Reduced fetal wellbeing
- Stillbirth in severe cases
Your obstetrician may recommend additional scans or fetal monitoring when necessary.
What Are the Complications of Untreated Preeclampsia?
Early diagnosis is important because severe preeclampsia can affect several organs.
Eclampsia
In some cases, the condition can progress to eclampsia, which involves seizures and requires emergency treatment.
HELLP Syndrome
HELLP syndrome is a serious complication involving:
- Hemolysis
- Elevated liver enzymes
- Low platelet count
Kidney and Liver Problems
Changes in blood pressure and organ function can affect the kidneys and liver.
Stroke
Very high blood pressure during pregnancy can increase the risk of serious cardiovascular complications, including stroke.
Placental Abruption
The placenta can separate from the uterus before delivery, potentially causing significant bleeding and creating risks for both mother and baby.
How Is Preeclampsia Diagnosed?
Doctors use several methods to evaluate a pregnant woman for preeclampsia and pregnancy hypertension.
Blood Pressure Check
Blood pressure is routinely measured during antenatal appointments. Persistently elevated readings may require further investigation.
Urine Test
A urine examination can help identify protein in the urine and assess kidney involvement.
Blood Tests
Depending on the situation, your doctor may check:
- Platelet count
- Liver function
- Kidney function
- Other indicators of organ involvement
Ultrasound and Fetal Monitoring
Ultrasound examinations can help monitor the baby’s growth and wellbeing. Additional fetal monitoring may be recommended depending on the severity of the condition.
How Is Preeclampsia Treated?
Treatment depends on the mother’s health, baby’s condition, gestational age and severity of the disease.
Medical management may include:
- Regular blood pressure monitoring
- Antihypertensive medicines
- Blood and urine tests
- Fetal growth monitoring
- Ultrasound examinations
- Medicines to reduce seizure risk in severe cases
- Corticosteroids when early delivery is anticipated
- Delivery when continuing the pregnancy becomes unsafe
Every pregnancy is different. Your obstetrician will determine the safest treatment plan based on your individual circumstances.
Can Preeclampsia Be Prevented?
There is no guaranteed method to prevent every case of preeclampsia. However, identifying risk factors early and attending regular antenatal appointments can support early detection.
For women with certain risk factors, a doctor may recommend preventive measures such as low-dose aspirin. Calcium supplementation may also be advised in specific circumstances.
Never start aspirin, calcium supplements or any other medicine during pregnancy without consulting your doctor.
When Should You See a Doctor?
Pregnant women should seek medical advice if they experience concerning symptoms such as:
- Severe or persistent headache
- Blurred vision
- Flashing lights or spots in vision
- Sudden swelling of the face or hands
- Severe upper abdominal pain
- Difficulty breathing
- Very high blood pressure
- Feeling suddenly or severely unwell
Immediate medical evaluation is especially important when several symptoms occur together.
Can Preeclampsia Occur After Delivery?
Yes. Postpartum preeclampsia can develop after childbirth, even when pregnancy was uncomplicated.
New symptoms such as severe headache, vision changes, upper abdominal pain or difficulty breathing after delivery should be evaluated without delay.
Mothers should continue paying attention to their health during the postpartum period rather than assuming that pregnancy-related complications end immediately after delivery.
How Can Regular Antenatal Care Help?
Regular antenatal appointments allow doctors to monitor the health of both mother and baby throughout pregnancy.
These visits may include:
- Blood pressure monitoring
- Urine testing
- Weight monitoring
- Fetal growth assessment
- Blood tests when required
- Ultrasound examinations
- Evaluation of pregnancy risk factors
Early detection gives your healthcare team an opportunity to monitor the condition and decide on appropriate treatment.
