Study: Pregnancy sickness apparently genetic

Pregnant women are three times more likely to suffer from severe morning sickness if their mothers did.

This is according to a study in the British Medical Journal.

Around 2 percent of women suffer excessive nausea and vomiting in pregnancy. The condition ends up sending many women to the hospital and can cause low birth weight and premature birth.

Norwegian researchers say their results suggest a genetic link between mothers and daughters, but shared lifestyle and environmental factors are also being considered.
