Thousands of New Mothers Experience Undiagnosed PTSD After Childbirth

A substantial number of women may be developing post-traumatic stress disorder after childbirth without being identified or receiving appropriate treatment, according to a new analysis led by researchers at the University of East Anglia. The report warns that birth-related psychological trauma is frequently overlooked during routine postnatal care, even though childbirth-related PTSD can affect a mother’s health, her relationship with her baby, decisions about future pregnancies and her willingness to seek medical help. The researchers estimate that around one in 20 postnatal women develop PTSD, a proportion that would represent tens of thousands of mothers across the United Kingdom. Their findings suggest that the true scale may be considerably larger than official diagnoses indicate, because many women are never assessed for the condition or are instead diagnosed with postnatal depression.

PTSD is a psychiatric disorder that can emerge after exposure to an event involving actual or threatened death, serious injury or extreme fear. In the context of childbirth, the triggering experience may include a medical emergency, severe pain, unexpected complications, loss of control, inadequate communication, invasive procedures or concern for the survival of the mother or baby. A birth does not have to be medically complicated for trauma to develop. The disorder may involve intrusive memories, distressing dreams, flashbacks, avoidance of reminders, heightened vigilance, persistent anxiety, emotional numbness and negative beliefs about oneself or the world. Physiologically, these symptoms reflect persistent activation of threat-response systems and impaired processing of the traumatic memory, leaving the person reacting to reminders as though the danger is still present.

The UEA analysis describes maternal suicide as the visible “tip of the iceberg” of a wider mental-health crisis. Recent UK figures identified suicide as the leading cause of death among women between six weeks and one year after pregnancy during 2021–2023. The researchers stress that suicide statistics cannot be used to calculate the prevalence of childbirth-related PTSD, but they illustrate the seriousness of untreated mental-health problems during the postnatal period. Behind the most severe outcomes are likely to be many women living with debilitating anxiety, intrusive recollections and avoidance, while continuing to care for a newborn under intense physical and emotional pressure. The combination can make symptoms difficult to distinguish from the exhaustion, mood changes and anxiety that commonly accompany early parenthood.

The report’s lead researcher, GP Megan Foreman of UEA’s Norwich Medical School, says that primary-care clinicians are often “diagnosing in the dark.” National guidance from the National Institute for Health and Care Excellence and NHS England refers to birth trauma, but the analysis found that general practitioners are not provided with sufficiently practical instructions for determining symptom severity, evaluating risk or deciding when specialist treatment is required. Many clinicians also report limited confidence and training in recognizing trauma-related disorders. In a standard six-to-eight-week postnatal consultation, a GP may have only a short appointment to assess the mother, discuss physical recovery, review contraception and examine or vaccinate the infant. Under those conditions, psychological symptoms may remain unspoken, particularly when the mother believes that distress is a normal consequence of childbirth or fears being judged.

A further concern is diagnostic overlap. Postnatal depression can involve low mood, loss of interest, guilt, sleep disturbance and thoughts of self-harm, while PTSD may also produce depression, irritability, insomnia and impaired concentration. However, the underlying mechanisms and recommended treatments are not identical. Depression is primarily characterized by persistent disturbances in mood and motivation, whereas PTSD includes trauma-linked re-experiencing, avoidance and physiological reactivity. If a woman describes feeling overwhelmed or unable to cope but is not asked about frightening memories, nightmares, panic or avoidance, the trauma component may be missed. The report warns that some women may therefore be prescribed antidepressants for presumed depression while the specialized psychological care required for PTSD is delayed.

Evidence-based treatment for PTSD generally focuses on trauma-oriented psychological interventions, including trauma-focused cognitive behavioral therapy and eye movement desensitization and reprocessing. These approaches aim to reduce avoidance, modify threatening interpretations and help the brain integrate traumatic memories so that reminders no longer trigger the same level of alarm. Antidepressants can be useful for some patients, particularly when depression or anxiety occurs alongside PTSD, but the analysis notes that they are generally less effective as a primary treatment for PTSD than specialist psychological interventions. NICE does not recommend antidepressants as the first-line treatment for PTSD. The distinction matters because an incorrect diagnosis can influence both the treatment offered and the speed with which a woman is referred to an appropriate service.

Untreated childbirth trauma can shape behaviour long after the original delivery. Some women repeatedly seek reassurance from doctors or emergency services because they fear that something is wrong with themselves or their baby. Others avoid healthcare entirely, including antenatal care in a later pregnancy, because medical settings, examinations or discussions of childbirth trigger memories of the earlier experience. The report says that some women request planned Caesarean sections in subsequent pregnancies as a way to regain control, while others reject recommended interventions or choose home birth despite high medical risk because they associate hospitals with the trauma. These decisions should not be interpreted simply as non-compliance. They may represent attempts to reduce perceived danger in the absence of effective psychological support.

The researchers are calling for a validated assessment tool that could be incorporated into the routine postnatal appointment, alongside better training for GPs and clearly defined referral pathways. Screening, however, would need to be carefully designed. A short questionnaire could identify symptoms such as intrusive recollections, avoidance and hyperarousal, but a positive result would not itself establish a diagnosis. Clinicians would need to consider the timing of symptoms, functional impairment, coexisting depression or anxiety, immediate safety concerns and the woman’s preferences for further care. The researchers also caution that asking about trauma abruptly or in front of family members may cause distress or make a mother feel retraumatized. Assessment should therefore be private, empathetic and separated where possible from the practical demands of examining a newborn.

The analysis, conducted by UEA in collaboration with City St George’s University of London and the University of Birmingham, presents the evidence gap as a health-system problem rather than an individual failure. GPs are the main gateway to specialist mental-health services for many new mothers, yet they face staff shortages, rising workloads and limited consultation time. Improving recognition of childbirth-related PTSD will require more than adding another question to a crowded appointment. It will depend on accessible psychological services, consistent clinical guidance, professional education and a system capable of responding when screening identifies significant trauma. The report, titled “Diagnosing in the dark: The childbirth-related post-traumatic stress disorder GP evidence gap,” is published in the British Journal of General Practice. Its central message is that childbirth-related PTSD is common enough to demand routine attention, but sensitive enough to require more than a tick-box diagnosis.
