Pregnancy Morning Sickness? There Could Be A Benefit…

Section: Morning sickness

New research suggests pregnant women who suffer from morning sickness could have healthier, more intelligent babies

Morning sickness might be one of the more uncomfortable symptoms of pregnancy (and whoever decided to call it morning sickness has obviously not been struck down with it until 10pm at night), but there could be an upside to it.

A study carried out at the Hospital for Sick Children in Toronto, Canada, looked at mothers who suffered morning sickness to any extent and found they were less likely to have low birth weight babies and the babies had a smaller chance of having birth defects.

Researchers looked at data from 10 separate studies conducted in five countries between 1992 and 2012, which included a total of 850,000 pregnant women.

The findings also showed that mothers who felt sick and vomited were less likely to have a premature birth – 6.4% compared with 9.5% who didn’t get morning sickness.

The study also tested the intelligence of babies born to mums who had morning sickness as they got older, discovering that they scored higher for IQ, language and overall behaviour.

Study author Gideon Koren, said, ‘This reveals a consistent, favourable effect of nausea and vomiting in pregnancy on rates of miscarriages, foetal growth, prematurity, and developmental outcomes.

‘Women with moderate to severe nausea and vomiting in pregnancy often experience major negative impact on their health and quality of life. Our analysis indicates that reassuring these women that their severe symptoms may be beneficial for their unborn babies, is logical.’

However, the study also looked at women who had hyperemesis gravidarum – extreme morning sickness – and found the benefits did not extend to their babies.

If you struggling with morning sickness – and around 90% of pregnant women will – find out how to cope.
