Migraine and complications in pregnancy linked together?

For gestational high blood pressure, 7% of pregnancies among women with migraine developed this condition compared to 5% among pregnancies in women without migraine.

Women with migraine may have a higher risk of pregnancy complications like preterm delivery, gestational high blood pressure and preeclampsia, according to a preliminary study released today, February 24, 2022, that will be presented at the American Academy of Neurology's 74th Annual Meeting being held in person in Seattle, April 2 to 7, 2022 and virtually, April 24 to 26, 2022.

Researchers also found that women with migraine with aura may have a somewhat higher risk of preeclampsia than women with migraine without aura. Auras are sensations that come before the headache, often visual disturbances such as flashing lights. Preeclampsia involves high blood pressure with additional symptoms, such as protein in the urine, during pregnancy, which can threaten the life of the mother and baby.

Researchers examined women's complications during pregnancy such as preterm delivery, defined as a baby born before 37 weeks gestation, gestational diabetes, gestational high blood pressure, preeclampsia, and low birthweight.

After adjusting for age, obesity, and other behavioral and health factors that could affect the risk of complications, researchers found that when compared to women without migraine, women with migraine had a 17% higher risk of preterm delivery, a 28% higher risk of gestational high blood pressure, and a 40% higher risk of preeclampsia.

Researchers found that migraine was not associated with gestational diabetes or low birthweight.

"While the risks of these complications are still quite low overall, women with a history of migraine should be aware of and consult with their doctor on potential pregnancy risks," said Purdue-Smithe.
