How Does Preeclampsia Affect the Mother and the Baby?
Pregnancy is often celebrated as a time of joy and anticipation, but it can also bring unexpected challenges. Preeclampsia in pregnancy is a complication marked by high blood pressure and signs of damage to vital organs. While many women navigate pregnancy without significant health issues, preeclampsia can pose severe risks to both mother and baby if left untreated.
As a Senior Consultant Obstetrician and Gynaecologist at Fortis La Femme, I have seen firsthand how critical it is to recognize and address this condition promptly. My commitment to women’s health drives me to share essential information and guidance, ensuring that mothers and families are well-prepared to manage potential complications.
This article will explore what happens during preeclampsia, the symptoms to watch out for, who is at risk, and how it impacts both the mother and the baby. My goal is to provide clear, accurate, and practical insights to help you understand and manage this serious pregnancy condition.

What Happens in Preeclampsia?
Preeclampsia is a serious pregnancy complication that usually develops after the 20th week of gestation. It is characterized by high blood pressure and signs of damage to organs, particularly the liver and kidneys. The condition can progress rapidly and may continue postpartum, posing risks to both mother and baby. While the exact cause remains uncertain, it is thought to arise from issues with placental function and abnormal development of maternal blood vessels.
Key Points of Preeclampsia in Pregnancy:
- Abnormal Placental Blood Vessels: The blood vessels in the placenta do not develop or function properly, reducing blood flow between the placenta and uterus.
- Endothelial Dysfunction: Harmful substances are released from the placenta, damaging the endothelial cells lining blood vessels, leading to endothelial dysfunction.
- Hypertension: Blood pressure rises significantly as blood vessels narrow and lose elasticity.
- Proteinuria: Increased pressure causes protein to leak into the urine, indicating kidney damage.
- Severe Complications: If left untreated, preeclampsia can progress to eclampsia (seizures) or HELLP syndrome (liver dysfunction and low platelet count).
- Life-Threatening Risks: Both the mother and baby are at risk of severe complications, including stroke, organ failure, and preterm birth.
Why Early Detection Matters:
Recognizing and managing preeclampsia early can significantly reduce health risks for both mother and baby. Timely intervention, regular monitoring, and proper medical care are crucial to preventing severe outcomes. If you experience symptoms like severe headaches, vision changes, or swelling, seek immediate medical attention.
Who is at Risk of Preeclampsia?
Certain women have a higher likelihood of developing preeclampsia due to various risk factors. Understanding these factors can help healthcare providers implement preventive measures and monitor high-risk pregnancies more closely.
Primary Risk Factors
- First Pregnancy: Women experiencing their first pregnancy are at higher risk.
- Age Factors: Pregnant women under 20 or over 35 are more likely to develop preeclampsia.
- Family History: A family history of preeclampsia significantly increases the risk.
- Multiple Pregnancies: Carrying twins, triplets, or more heightens the likelihood.
- Previous Preeclampsia: Women who have had preeclampsia in a prior pregnancy face an increased risk in subsequent pregnancies.
Health Conditions
- Chronic Hypertension: Pre-existing high blood pressure elevates risk.
- Diabetes and Kidney Disease: These conditions make it harder for the body to maintain normal blood pressure levels.
- Obesity: Excessive weight gain during pregnancy or pre-pregnancy obesity is a known risk factor.
- Autoimmune Disorders: Conditions such as lupus or antiphospholipid syndrome are associated with higher risk.
By recognizing these risk factors, healthcare professionals can offer tailored care and monitoring to those at greater risk, helping to manage symptoms and reduce potential complications.
Symptoms of Preeclampsia
Preeclampsia can manifest through a range of symptoms, some of which may seem like typical pregnancy discomforts. However, it is crucial to distinguish these symptoms and seek medical attention if they occur.
Common Symptoms:
- High Blood Pressure: A reading of 140/90 mm Hg or higher on two separate occasions at least four hours apart.
- Proteinuria: Excess protein in the urine, detectable through laboratory testing.
- Severe Headaches: Persistent and intense headaches that do not subside with usual pain relievers.
- Visual Disturbances: Blurred vision, seeing spots or flashing lights, and light sensitivity.
- Upper Abdominal Pain: Pain located under the ribs, usually on the right side.
- Nausea and Vomiting: Especially if it appears suddenly after mid-pregnancy.
- Reduced Urine Output: A noticeable decrease in urination frequency or volume.
- Sudden Weight Gain: Rapid weight increase, often linked to fluid retention.
- Swelling (Edema): Particularly in the hands, feet, and face.
Severe Symptoms:
- Breathlessness: Indicating fluid in the lungs (pulmonary edema).
- Seizures: Sign of progression to eclampsia.
- Confusion and Altered Mental State: Often related to central nervous system involvement.
If any of these symptoms occur, immediate medical evaluation is necessary to assess the severity and implement timely interventions.
How Preeclampsia Affects the Mother
Preeclampsia poses significant health risks to mothers, affecting multiple organ systems. Its impact on maternal health can be both immediate and long-term, requiring vigilant monitoring and management.
Cardiovascular Complications
The most common effect of preeclampsia is a sharp rise in blood pressure. This sudden hypertension increases the risk of cardiovascular events like stroke and heart attack. Blood vessels may constrict and become damaged, leading to poor blood circulation and potential clot formation.
Renal Complications
One hallmark of preeclampsia is proteinuria, which reflects kidney dysfunction. The kidneys fail to filter blood efficiently, causing protein to leak into the urine. Severe cases can lead to acute kidney failure, requiring intensive medical support.
Liver Damage and HELLP Syndrome
HELLP syndrome is a severe complication characterized by hemolysis, elevated liver enzymes, and low platelet count. It can result in liver damage and even rupture, leading to life-threatening internal bleeding. Women experiencing HELLP syndrome often present with right upper abdominal pain and tenderness.
Neurological Effects
Severe headaches, visual disturbances, and confusion are common neurological manifestations. These symptoms indicate cerebral edema or swelling of the brain. In extreme cases, eclampsia occurs, causing seizures that put both mother and baby at risk.
Long-Term Health Risks
Women who have had preeclampsia face an increased risk of chronic hypertension and cardiovascular diseases later in life. Regular follow-up care postpartum is essential to monitor blood pressure and overall cardiovascular health.
How Preeclampsia Affects the Baby
The baby’s well-being is equally jeopardized when the mother develops preeclampsia. The primary concern is intrauterine growth restriction (IUGR), which occurs due to poor blood flow from the placenta. This restricts the baby’s oxygen and nutrient supply, resulting in low birth weight and developmental issues.
Preterm Birth
In severe cases, early delivery may become necessary to protect both the mother and baby. Preterm birth increases the likelihood of respiratory distress syndrome (RDS), as the baby’s lungs may not be fully developed. Premature babies often require neonatal intensive care to manage breathing difficulties and maintain body temperature.
Neurological Implications
Babies born prematurely due to preeclampsia may face long-term neurological challenges, including cerebral palsy and developmental delays. The severity of these outcomes often correlates with the degree of prematurity and birth weight.
Stillbirth and Placental Complications
Placental abruption, where the placenta detaches from the uterine wall prematurely, is a severe complication that can result in stillbirth. Monitoring fetal movement and regular ultrasounds are crucial in assessing the baby’s condition and planning safe delivery.

Conclusion
Preeclampsia in pregnancy can be critical complication that affects both the mother and baby. Its unpredictable nature and potential severity make it a priority for early detection and diligent management. By understanding the symptoms, risk factors, and potential impacts, healthcare providers and mothers can work together to ensure the best possible outcomes. Regular prenatal care, blood pressure monitoring, and prompt intervention are essential for safeguarding maternal and fetal health. If you suspect preeclampsia, seek immediate medical attention to mitigate risks and support a healthier pregnancy journey.
