London, Apr 30 (ANI): Mothers-to-be are three times more likely to suffer from severe morning sickness if their mums did, a new study claims.
According to the study of 2.3 million births, mothers who suffer excessive nausea and vomiting in pregnancy - known as hyperemesis gravidarum - are at a threefold higher rate of having the condition if their mums had it too, reports The BBC.
To reach the conclusion, boffins analysed birth records, which included information on pregnancy complications, from 1967 to 2006.
Writing in the British Medical Journal, they said the study "shed a new light" on the causes of hyperemesis in pregnancy.
"It might lead to a better appreciation of the underlying biology," they added. (ANI)
