Severe nausea in pregnancy linked to 50% higher risk of mental health issuesHyperemesis gravidarum during pregnancy raises the risk of mental health issues by over 50%, including post-partum depression, psychosis, and PTSD. Severe HG can cause metabolic disturbances, underlining the importance of mental health support and specialist care. Women with HG experience prolonged and severe nausea and vomiting, leading to dehydration and weight loss. The researchers also examined whether this categorisation is correlated with mental health outcomes. This finding highlights the importance of adequate mental health screening and support for all women with HG, regardless of perceived severity.
