Taking marijuana for the treatment of nausea and vomiting in pregnancy may cause brain problems in newborns as well as worsen the mother’s health, according to a study on Monday.
About 70 per cent of pregnancies experience morning sickness in
pregnancy, known medically as hyperemesis gravidarum, and characterised by
nausea and vomiting. In severe cases, it can prevent pregnant women from eating
and drinking properly, leading to weight loss and dehydration.
However, resorting to cannabis may be harmful to the health of
both the mother and child, according to a review of studies published in CMAJ
(Canadian Medical Association Journal).
“Use of cannabis in pregnancy has been associated with adverse
neurocognitive outcomes in offspring, as well as other adverse pregnancy
outcomes. Therefore, we advise against the use of cannabis in pregnancy,” said
Dr Larissa Jansen, Amsterdam Reproduction and Development Research Institute,
Erasmus MC, Netherlands.
To date, the cause of morning sickness is not completely
understood. Yet pregnancy at a young age, a female foetus, multiple or molar
pregnancies, underlying medical conditions, and a history of the condition
during previous pregnancies are some known risk factors.
“Hyperemesis gravidarum can have detrimental effects on maternal
quality of life and may lead to short and long-term adverse outcomes among
offspring,” said Dr Larissa.
“Management of hyperemesis gravidarum requires considerable
healthcare resources, as it is a common reason for hospital admission and
emergency department visits in the first trimester,” she added.
