Best Diet for Preeclampsia

Preeclampsia is a serious condition that can develop during pregnancy after week 20 or even postpartum. It occurs in 5 to 7 % of all pregnancies and is one of the leading causes of maternal morbidity. (1)

What is Preeclampsia?


Preeclampsia is having high blood pressure and at least one of the following symptoms: (2


  • Protein in your urine 

  • Low or decreased blood platelets

  • Liver or kidney issues

  • Fluid in the lungs (pulmonary edema)

  • Headaches 

  • Vision impairment

Don't freak out! This may sound scary. But, most women who have preeclampsia deliver healthy babies and fully recover. It is important to detect it early and receive proper prenatal care to prevent complications. 


Gestational Hypertension vs Preeclampsia 


Gestational hypertension or pregnancy induced hypertension (PIH) and preeclampsia are different. PIH is when a woman develops high blood pressure in the second half of pregnancy without any other symptoms. Preeclampsia is a multisystem disorder.(3)


Signs and Symptoms 


Preeclampsia can sometimes develop without any signs at all, but the most common are


  • High blood pressure 

  • Swelling of the face, hands, or feet

  • Protein in the urine

According to the American Pregnancy Association, blood pressure that is > 140/90 mm Hg, documented on 2 occasions and at least 4 hours apart, is abnormal and can be early signs of preeclampsia. (4)

As preeclampsia progresses, advanced signs and symptoms may include:(5)


  • Severe headaches

  • Changes in vision: blurred vision, flashing lights, oversensitivity to light,

  • Abdominal pain, or pain under the ribs

  • Decreased urination

  • Shortness of breath or burning behind the sternum

How Do You Get Preeclampsia During Pregnancy?


The exact cause of preeclampsia is unknown, but ongoing research is shedding light on potential causes. Some theories involve the placenta, which nourishes the baby. As the baby grows, more nutrients and resources are required from the mother. Therefore, the mother's health is crucial. Pre-existing diseases, genetic factors, and vitamin and mineral status are also important considerations.  (4)

Who Is At Risk?


  • First-time moms

  • Women with a personal history of preeclampsia

  • Family history

  • Age: Women under 20 or over 40 years old are at a higher risk

  • Certain pre-existing medical conditions

  • Women having twins or triplets 

  • Obesity: Being overweight or obese before pregnancy increases the risk

  • Certain ethnicities: African-American women have a higher incidence of preeclampsia.



Diet Approaches for Lowering Blood Pressure


If you're wondering how to prevent preeclampsia naturally, consider two evidence-based diets that can help lower blood pressure:


1. The DASH Diet


The DASH diet (Dietary Approaches to Stop Hypertension) emphasizes fruits, vegetables, whole grains, low-fat dairy, and plant protein while limiting red meat, processed meat, sweets, and sugar-sweetened beverages.  (7)


2. The Mediterranean Diet


The Mediterranean diet prioritizes healthy fats like fish, nuts, and seeds, large amounts of vegetables and fruits, and minimal added sugar, processed foods, and saturated fats.


While there's no magic preeclampsia diet, making small dietary changes can help manage blood pressure. Here are some things to think about (8):


  • Try to eat 25–30 grams of fiber every day.

  • Eat at least 5 cups of fruits and veggies every day.

  • If you don't like seafood, you can take special pills with fish oils.

  • Make sure you get enough vitamin D. (9)

  • Eat foods with potassium.

  • Don't eat too much fatty, salty, or sugary foods.

There are no foods to avoid with preeclampsia; moderation is key. You can still enjoy your favorite foods in small amounts.
