Hypertensive disorders of pregnancy, such as preeclampsia, are the most common and dangerous pregnancy complications, occurring in 5-8% of pregnancies. An animal study revealed that placental ischemia-induced hypertension in rats was alleviated by exercise. Researcher Jeff Gilbert explains, “The data from our study raise the possibility that exercise regimens, if started before pregnancy and maintained through most of gestation, may be an important way for women to mitigate the risk of preeclampsia.”
