Women with nausea early in pregnancy were half as likely to have miscarriages and stillbirths as those who sailed through the first few months. STUDY STRENGTHSUnlike some previous studies linking morning sickness with fewer miscarriages, the new research had data on women even before they became pregnant, so they were able to include miscarriages that occurred soon after conception. Some previous studies asked women months later to recall whether they had morning sickness — a weaker method than using daily diaries. THE REASONSCauses of morning sickness are uncertain but it has been linked with high hormone levels that occur early in pregnancy. THE BOTTOM LINEHinkle said the results should be reassuring to women concerned that morning sickness could be harmful.
