Study: HG in Pregnancy Linked to Higher Mental Health Risks
Being very sick during pregnancy with severe nausea and vomiting is called HG.
A new study found women with HG might face greater risks of mental health problems, like feeling sad or anxious after giving birth.
The study shows HG could double the chance of some of these problems.
The study also found that women with the more severe type of HG didn't necessarily have worse mental health, highlighting the need for support for all women with HG.
HG affects up to 3.6% of pregnancies.
HG is a common cause of first trimester hospitalization.
Study links HG to increased mental health condition risks.
Over 50% increased risk found in 13 conditions.
Risk of post-partum depression 2.7 times greater.
