When you're bent over with nausea and clutching your belly bump, don't blame your wee one for your misery -- scientists have found a link between the severity of your morning sickness and that of your own mother.

BBC News reports that a study by Norwegian researchers indicates that pregnant women are three times more likely to suffer from severe morning sickness if their mothers did, as well.

Hyperemesis gravidarum
, or excessive nausea and vomiting in pregnancy, affects about 2 percent of all pregnant women, and can sometimes even require hospitalization. The Norwegian study, which looked at 2.3 million births, showed that women whose mothers had the condition are three times more likely to suffer from it, as well. The results could help women know their risk for the disease.

Hyperemesis is very different from typical morning sickness, which generally disappears after the first trimester. Instead, moms who suffer from it have excessive nausea that begins before the 22nd week of pregnancy and, in its most serious form, can lead to dangerous health conditions including dehydration and weight loss.

It's also the most common reason that pregnant women are admitted to the hospital early. Hyperemesis also takes the blame for some babies with low birth weights, and even premature birth. Researchers tell BBC News that previous studies asserted that the condition was caused by psychological issues.

The study, published in the British Medical Journal, also revealed that mom and daughter may share lifestyle risk factors that contribute to the condition.
