Assumption: There is no known way to prevent preeclampsia.

According to the Preeclampsia Foundation,

Thousands of women and babies die or get very sick each year from a dangerous condition called preeclampsia, a life-threatening disorder that occurs only during pregnancy and the postpartum period. Preeclampsia and related disorders such as HELLP syndrome and eclampsia are most often characterized by a rapid rise in blood pressure that can lead to seizure, stroke, multiple organ failure and death of the mother and/or baby.

There are many theories about the causes of preeclampsia and how to prevent it, but none have been proven.  However, there are studies taking place that hope to shed some light on the topic.  This is a study that demonstrates that many women who experience preeclampsia have notably low levels of vitamin D.

My Views:
Lately, doctors have been recommending increased vitamin D for maintaining health in a variety of ways.  My mom has been told to increase her vitamin D and my gynecologist recommended a multivitamin with increased vitamin D.  My pediatrician is even recommending vitamin D supplements for my infant!  It seems that vitamin D is an important nutrient for many facets of health and apparently, pregnancy is one of them.  Check your prenatal multivitamin and ask your doctor or midwife about the possibility of increasing your dose of D!
