Bed rest is essential. Delivery is the most preferred treatment if the fetus has grown enough to survive outside the womb. Careful monitoring of blood pressure, weight checks, and regular urine tests for protein will help timely treatment. The goal of treatment is to manage the condition until delivery (after 36 weeks of pregnancy) can be achieved.
Emergency delivery of the baby may be necessary if any of the following conditions occur:

Destruction of red blood cells, known as hemolysis.

Elevated levels in liver function tests.

Falling platelet count.

Pain in the right upper abdomen.

Persistent and severe headache.

Signs of kidney failure.

Very high blood pressure for more than 24 hours

If delivery isn't possible because it's early pregnancy, steps should be taken to manage the pre eclampsia until the baby can be delivered. These steps include reducing the blood pressure with bed-rest or medicines, and monitoring the baby. In some cases, hospitalization may be necessary.

Reducing daily salt intake helps in long term to reduce the blood pressure.

A caesarean section may be needed. Anticonvulsants may be used to prevent seizures.
My name is David Papandreas and I conceived a Mom and Dad's Guide to Preeclampsia while my incredible wife and I found ourselves searching helplessly on the internet for what to expect. It was amazing that the websites only discussed the characteristics that define preeclampsia and offer no practical knowledge. Pregnant with our first child, we were scared not knowing what this meant and how we would react to the diagnosis.
Now, 9 months after our baby was born happy, healthy, and whole, we want to share our story and inspire the 400,000 pregnant ladies every year in the U.S. that develop preeclampsia. The book features useful tips, strategies and real stories to help others deal with the condition.
