The Health Risks of Headaches During Pregnancy

By Petra Vollavic

Being pregnant comes with an increase in risk to the health of you and your unborn child. Today we look at the connection between migraines during pregnancy and how this affects you and your babys health.

Experiencing migraines while pregnant has been linked to an increase in the chance of having a stroke, according to a study in the United States. It found that you were fifteen times more likely to have a stroke compared to woman who were not pregnant.

Information was collated from over 33,000 pregnant women who were also experiencing migraines.

Age was a determining factor, as women over the age of 40 were nearly two and a half times more likely to suffer from a migraine than women under the age of twenty. White women were also more likely to experience migraines during pregnancy than any other race or ethnicity.

Migraines have also been linked to a rise in the risk of heart disease, blood clots, high blood pressure, high cholesterol and diabetes. They suggest it is possible that the migraine itself is an indication that the cardiovascular system is not working as well as it should be.

The authors suggest that the most logical explanation for the findings lies in the interaction between migraines and the normal physiological changes during pregnancy (such as increased blood volume and heart rate) which put extra stress on the vascular system.

Previous studies have pointed towards a problem with the cells that make up the inner wall of blood vessels. It is thought that they don't function correctly when a woman is pregnant and also suffers from migraines.

The study further links migraines with an increase in the risk of stroke and heart disease, particularly when accompanied with a visual distortion or an aura. - 32503
