As much joy as a pregnancy brings, there are also a lot of worries that accompany it. While preeclampsia may summon dated references like Lady Sybil’s death on Downton Abbey, it still affects women today. According to the CDC, 1 in 25 pregnancies in the United States are affected by preeclampsia—the sudden elevation of the mother’s blood pressure after the 20^th week of pregnancy.

What is it and what are the causes?

Preeclampsia usually begins after the 20^th week of pregnancy, with some rare cases of postpartum preeclampsia. It is characterized by high blood pressure, as well as damage to the liver and kidneys. There may also be protein in the women’s urine and low levels of platelets. For a preeclampsia diagnosis, the mother’s blood pressure during pregnancy needs to be persistent and other symptoms of organ damage, low platelets, fluid in the lungs, and/or signs of brain trouble need to be present.

The causes of preeclampsia have not yet been precisely identified. However, potential causes include genetic factors, blood vessel problems, and chronic hypertension, as well as metabolic diseases or autoimmune disorders. There are some known risk factors that may increase the chances of preeclampsia, such as:

• history of preeclampsia in your family
• preeclampsia in a previous pregnancy
• having a multiple pregnancy or becoming pregnant via IVF
• being over the age of 40
• having obesity
• being pregnant for the first time

How Can it be Treated?

To receive a diagnosis and treatment, watch out for the following symptoms:

• signs of kidney problems and excess protein in your urine
• severe headaches and changes in vision
• upper abdominal pain
• nausea or vomiting, as well as shortness of breath

Some symptoms may go unnoticed, such as sudden weight gain and swelling, since they are normal symptoms of a pregnancy, so watch out for a combination of symptoms and attend all your prenatal appointments to ensure you and your baby’s safety.

With preeclampsia, you are at increased risk of seizures, stroke, severe bleeding, and placental abruption. As such, the most effective treatment is delivery. Possible medications may include antihypertensives to help lower your blood pressure, corticosteroids that can temporarily improve liver and platelet function, as well as anticonvulsant medications to prevent seizures. Severe cases of preeclampsia may require you to be hospitalized, but by far the most effective treatment is delivery of the baby. Be wary of the traditional suggestion of “bed rest,” as in this case it can actually be more harmful since it increases the risk of blood clots.
