The risk with no label: perinatal mental illness and maternal death

A medication label lists the risks of the medication. Nothing on it lists the risks of the illness going untreated, and that asymmetry is why a decision made from labels alone is not balanced. This stop puts the other column on the page. If it is heavy going, that is its honest weight - and crisis lines exist for anyone reading this in a bad moment.

Significant findings

In the United States, maternal mortality review committees in 38 states examined 525 pregnancy-related deaths from 2020 and identified an underlying cause for 511. Mental health conditions were the single most frequent at 115 deaths - 22.5% - ahead of cardiovascular conditions (16.6%), infection (16.4%) and haemorrhage (11.2%). The category covers, in the committees' own definition, suicide, overdose or poisoning related to substance use disorder, and other deaths judged related to a mental health condition. "Pregnancy-related" means a death during pregnancy or within one year of its end that the committee judged causally related to the pregnancy or its management. Forty-seven per cent occurred 7 to 365 days postpartum, and committees judged 430 of 515 - 83.5% - preventable (cdc.gov/maternal-mortality/php/data-research).

One precision, because the two systems get confused: this is maternal mortality review committee data, not the CDC's Pregnancy Mortality Surveillance System, whose leading underlying cause in 2020 and 2021 was infection driven by COVID-19.

The peer-reviewed analysis anchoring this row covers an earlier, smaller set: 421 such deaths with a committee-determined cause across 14 states, 2008-2017. Mental health conditions accounted for 11%. Those deaths were likelier to be judged preventable (100% against 64%) and far likelier to occur late - 63% between 43 and 365 days postpartum against 18%. Sixty-three per cent were suicides. The 11% and the 22.5% are not interchangeable: different eras, different states, and a coding change for substance-use-related deaths.

The UK confidential enquiry reaches the same place independently. In 2021-2023, across the UK and Ireland, 155 women died from psychiatric causes in pregnancy or the following year - 7.14 per 100,000 maternities (95% CI 6.06-8.36) - of which 88 were suicides, 4.06 per 100,000 (3.25-5.00), up significantly from 2.64 in 2017-2019 (RR 1.54, 1.10-2.17). It states that maternal suicide is now the leading cause of death between six weeks and one year after pregnancy ends, and that psychiatric causes account for 34% of maternal deaths in that window (npeu.ox.ac.uk/mbrrace-uk, MBRRACE-UK 2025).

Which is why the guidance reads as it does. ACOG's 2023 clinical practice guideline "recommends against withholding or discontinuing medications for mental health conditions due to pregnancy or lactation status alone" and tells clinicians to "consider untreated or inadequately treated mental health disorders an exposure" (Obstet Gynecol 2023, doi:10.1097/AOG.0000000000005202). NICE guideline CG192 tells UK clinicians to discuss, in one conversation, the risks of each treatment, the background risk from the mental health problem, and "the risk or harms to the woman and the fetus or baby associated with stopping or changing a treatment" (nice.org.uk/guidance/cg192, rec 1.4.6).

Worth asking

This trail has no recommendation to give, deliberately: every stop ends with a question because the decision belongs to you and the people who know your history. The ones worth carrying out hold both columns at once: what is documented about the specific medication I take rather than its class; what is documented about my own illness untreated, and what it has done before; what the first year after birth would look like on each option, since that is when this stop's risk concentrates; and who I would contact, and how fast, if things changed. Bring them to a prescriber and an obstetrician together. If you are struggling right now, that is not a question to save for an appointment - a crisis line answers immediately.
