Pregnancy is a period of intense medical oversight, with regular prenatal appointments designed to address concerns and detect potential complications. Among these, preeclampsia stands out as particularly crucial to monitor.
This condition, characterized by high blood pressure during pregnancy, often emerges in the third trimester, although it can appear as early as 20 weeks or even postpartum, according to Dr. Sarosh Rana, a maternal-fetal medicine specialist at the University of Chicago Medicine. Dangerously, preeclampsia can be asymptomatic, making routine prenatal screening essential.
Untreated, preeclampsia can have severe consequences for both mother and baby. Maternal complications range from organ failure and seizures to fluid buildup in the lungs. High protein levels in the urine, another symptom, can lead to dehydration, kidney problems, and compromised immunity. For the baby, preeclampsia increases the risk of growth restriction, stillbirth, and other prematurity-related health issues. As Dr. Rana emphasizes, it's a leading cause of maternal and fetal illness and death globally.
According to the Cleveland Clinic, preeclampsia affects approximately 5% to 8% of pregnancies in the US and contributes to around 15% of premature births. Eleni Tsigas, CEO of the Preeclampsia Foundation, points out that while there's currently no cure or guaranteed prevention, strategies exist to mitigate risk and manage the condition if it develops. Early detection through regular prenatal care is paramount for timely intervention and improved outcomes.
Preeclampsia: Symptoms, Causes, and Treatment
Preeclampsia, a pregnancy-specific condition, often presents without noticeable symptoms. However, some women experience headaches, abdominal pain, shortness of breath, a burning sensation behind the sternum, nausea and vomiting, cognitive difficulties, increased anxiety, and vision changes like light sensitivity, blurred vision, or flashing lights/auras.
Routine prenatal checkups are crucial for detecting preeclampsia, as it's a common complication affecting all pregnant individuals. Dr. Leslie Moroz, a maternal-fetal medicine specialist at Yale Medicine, emphasizes that regular blood pressure monitoring during these visits is key, allowing doctors to identify rising or elevated levels indicative of the condition.
The exact causes of preeclampsia remain unclear, although the placenta's role is central. Experts agree that women with pre-existing conditions like chronic hypertension, obesity, metabolic disorders (e.g., diabetes), and autoimmune diseases (e.g., lupus) face a higher risk. While the reasons for incomplete placental development are still being researched, genetic, immunological, and environmental factors are likely involved.
Treatment for preeclampsia varies depending on the severity and the pregnancy's stage. If premature delivery poses risks to the baby, management often involves medication, a low-sodium diet, increased water intake, and more frequent prenatal monitoring. The American College of Obstetrics and Gynecology also recommends low-dose aspirin therapy from diagnosis until delivery.
Further interventions may be necessary depending on the gestational age and the baby's health, the mother's overall health and age, and the disease's progression. These include close blood pressure monitoring and lab tests assessing kidney and liver function, as well as blood clotting ability.
Ultimately, delivering the baby is the only definitive cure for preeclampsia. The timing of delivery requires careful consideration, balancing the risks of prematurity against the dangers of continued preeclampsia, as explained by Dr. Moroz.
Fortunately, the majority of women experience a full recovery after delivery, once the placenta is no longer a contributing factor.
