Understanding Preeclampsia Symptoms: Risks & Treatment

Being pregnant is an exciting journey, but sometimes concerns can arise. One such concern is preeclampsia, a

What is Preeclampsia?

Preeclampsia is a serious condition that affects approximately 5% of pregnancies. It is primarily characterised by two main indicators: high blood pressure and the presence of protein in your urine. While it might sound alarming, understanding the underlying cause helps in its management. The condition is ultimately caused by an issue with the placenta, the organ that develops during pregnancy to provide oxygen and nutrients to your growing baby.

The Science Behind Preeclampsia Symptoms

In a healthy pregnancy, the blood vessels connecting to the placenta are wide and open, ensuring a consistent and efficient supply of energy and blood flow to the baby. However, with preeclampsia, these blood vessels are narrower. This restriction means your body can’t deliver blood flow to the placenta as efficiently as needed. To compensate, your body raises its blood pressure, leading to the key preeclampsia symptoms.

If preeclampsia is not managed effectively, it can impact both the mother and the baby. In the mother, it can affect vital organs such as the liver and kidneys, and even interfere with blood clotting systems. This is why early detection and careful management of preeclampsia symptoms are so important.

Identifying Preeclampsia Symptoms: Key Risk Factors

Certain factors can increase an expectant mother’s risk of developing preeclampsia. These are typically categorised into higher risk and moderate risk factors:

Higher Risk Factors:

• Pre-existing high blood pressure: If you had high blood pressure before becoming pregnant.
• Previous preeclampsia: If you experienced preeclampsia in a prior pregnancy.
• Type 1 or Type 2 diabetes: Conditions like diabetes can increase your risk.
• Kidney problems: Any pre-existing kidney issues.

Moderate Risk Factors:

• Age: Being over 40 years old.
• High BMI: A high Body Mass Index (BMI) is a significant modifiable risk factor. For more information, see our articles on obesity and weight loss.
• Family history: If there’s a family history of preeclampsia.
• Multiple pregnancy: Being pregnant with more than one baby (e.g., twins, triplets).

It’s important to note that if you have two or more moderate risk factors, you might be considered at high risk. Your weight plays a substantial role, as the risk of preeclampsia almost doubles when your BMI indicates you are overweight. Managing your weight, even before pregnancy, is one of the most modifiable risk factors within your control.

Managing Preeclampsia Symptoms and Treatment Options

For those identified as high risk (either due to one high-risk factor or a combination of moderate ones), a common preventative measure is a low dose of aspirin, often started from week 12 of pregnancy. Aspirin is one of the oldest and safest medications available, and it helps to decrease the risk of preeclampsia for both mother and baby by improving blood flow through the placenta.

Once diagnosed, you will be closely monitored by your healthcare team. The only definitive “cure” for preeclampsia is the birth of the baby and the removal of the placenta. However, to manage the preeclampsia symptoms and ensure the well-being of both mother and baby, various treatments may be employed:

• Blood pressure medication: Specific medications, such as nifedipine or labetalol, that are safe to use during pregnancy may be prescribed to lower your blood pressure.
• Early delivery: In some cases, to prevent complications, you might be advised to deliver the baby sooner than week 40, often around week 37 or 38.
• Magnesium: In more severe cases, magnesium might be administered to prevent seizures (eclampsia), which is a serious complication of preeclampsia.

All treatment decisions will be made in close consultation with your healthcare professional, taking into account your individual circumstances and the severity of your preeclampsia symptoms.

What Preeclampsia Symptoms Should You Look Out For?

Thanks to routine prenatal care, preeclampsia is often detected early through regular blood pressure checks and urine tests for protein. This means healthcare professionals can often identify the condition even before you experience noticeable preeclampsia symptoms. However, it’s vital to be aware of the signs that warrant immediate medical attention.

Common preeclampsia symptoms to watch for include:

• Headaches: Persistent or severe headaches.
• Blurry vision: Changes in vision, such as blurred vision or seeing flashing lights.
• Swelling: Sudden or significant swelling in your hands or face. While some swelling is normal in pregnancy, a sudden increase can be a red flag.
• Nausea and vomiting: While common in early pregnancy, sudden onset of nausea and vomiting later in pregnancy can be a symptom.
• Feeling generally unwell: A sudden feeling of being unwell.

If you experience any of these severe or sudden preeclampsia symptoms, it is crucial to seek immediate medical attention by going to the hospital as quickly as possible. Your healthcare provider will also conduct specific tests like liver function tests, kidney function tests, and platelet counts to monitor the condition.

Life After Preeclampsia: Long-Term Health & Future Pregnancies

The good news is that preeclampsia typically improves significantly, or even resolves, once the baby is born and the placenta is delivered. However, having experienced preeclampsia during pregnancy is an important indicator for your long-term health. It is considered a risk factor for developing heart disease and other heart conditions later in life.

Therefore, maintaining a healthy lifestyle becomes even more important after a preeclampsia diagnosis. The same risk factors that contribute to preeclampsia, such as high BMI and insulin resistance, are also linked to heart conditions. Focusing on a healthy weight and metabolic health through diet and exercise can significantly mitigate these future risks. You can find more advice on general health and women’s health on our blog.

If you’ve had preeclampsia in one pregnancy, you have a higher risk of it recurring in subsequent pregnancies. For this reason, future pregnancies will be monitored even more carefully, and you may be advised to start low-dose aspirin from as early as week 12 as a preventative measure. Always discuss your medical history and any concerns with your healthcare professional to ensure the best possible care for you and your baby.
