> Preeclampsia is a serious pregnancy condition marked by high blood pressure and potential organ damage, typically appearing after 20 weeks of gestation or postpartum.

Preeclampsia is a significant health concern during pregnancy, characterized by elevated blood pressure and signs of damage to other organ systems, most commonly after 20 weeks of pregnancy or even after birth. It's a condition that can feel overwhelming to learn about, but understanding the signs and what the evidence suggests can help you feel more clear and confident.

## What it is

At its core, preeclampsia involves blood pressure readings of 140/90 mmHg or higher on two separate occasions, alongside either protein in the urine or other signs of organ damage. While some pregnancy changes, like [Pregnancy Swelling (Edema)](/conditions/pregnancy-swelling), can be common and benign, the sudden or severe onset of swelling, especially in the face or hands, can be a warning sign with preeclampsia. It's important to remember that this condition affects a notable percentage of pregnancies globally and is a leading cause of maternal and perinatal health complications.

## What it tends to feel like

For many, preeclampsia can develop without immediate, obvious symptoms, which is why regular prenatal check-ups are so important. However, when symptoms do appear, they can be quite distinct and warrant immediate attention. These might include a severe headache that doesn't go away, changes in vision such as blurriness or seeing spots, sudden and severe swelling, particularly in the face and hands, or pain in the upper right abdomen (epigastric pain). Sometimes, general discomfort or changes in sleep patterns, similar to what might lead to [Pregnancy Insomnia](/conditions/insomnia-pregnancy), can be present, but it’s the specific cluster of severe symptoms that points towards preeclampsia. It's a time when tuning into your body and communicating any unusual feelings to your care team is incredibly valuable.

## What the evidence says helps

Research offers some clear guidance on reducing the risk of preeclampsia for those at higher risk. For instance, low-dose aspirin (81mg daily) taken between 12 and 28 weeks of pregnancy has been shown to reduce the risk by 20-30% in individuals identified as high-risk. Additionally, for people in populations with low dietary calcium intake, calcium supplementation (1.5-2g daily) may also help reduce the risk. These are proactive steps that you can discuss with your provider to see if they are a good fit for your unique situation. It's about making informed decisions collaboratively with your care team. While some skin changes like [Melasma — Mask of Pregnancy](/conditions/melasma) are often just cosmetic, preeclampsia prevention is about supporting your overall systemic health.

## Working with your care team

The only definitive treatment for preeclampsia is delivery, but the timing of that delivery depends on many factors, including the severity of the condition, your gestational age, and the well-being of both you and your baby. This is a complex decision that you get to make in close collaboration with your medical provider. It's also crucial to be aware that preeclampsia can occur postpartum, typically within seven days of delivery. This postpartum presentation is sometimes underrecognized, so continuing to monitor your body and communicate any concerns after birth is just as important. Your provider is your best resource for your specific situation, and they can help you understand all your options and make choices that feel right for you.
