Extreme morning sickness a novel long-term risk factor for CVD: study

Guidelines should include hyperemesis gravidarum as a pregnancy-related cardiovascular risk factor, Canadian doctors say.

Women with hyperemesis gravidarum are almost 50% more likely to be hospitalised for cardiovascular events in the decades after delivery than those without hyperemesis, a large cohort study shows.

This risk was even higher among women with a history of pre-eclampsia, according to Canadian doctors, who followed more than 1.4 million women from pregnancy for up to 30 years.
