Some degree of worry during pregnancy is normal. Worry about the baby's health, about the birth, about the transition to parenthood – these are reasonable responses to a genuinely significant life event with real unknowns. The distinction between normal worry and an anxiety disorder that warrants treatment is not about the content of the thoughts but about their intensity, persistence, and impact on daily functioning.
Antenatal anxiety tends to be under-recognised by both health professionals and the pregnant person themselves, partly because the cultural narrative around pregnancy presents it as an entirely joyful experience, and expressing fear or persistent dread can feel ungrateful or abnormal. It is neither. Anxiety in pregnancy is more common than postnatal depression, and treating it matters – both for the pregnant person's wellbeing and for outcomes after birth.

How Common It Is
Around 15-20% of pregnant women experience clinically significant anxiety during pregnancy. Prenatal anxiety is at least as prevalent as postnatal depression (PND) and often precedes it: untreated antenatal anxiety is one of the strongest risk factors for PND. The two conditions frequently co-occur.
The Avon Longitudinal Study of Parents and Children (ALSPAC), one of the world's most comprehensive birth cohort studies, documented high rates of anxiety in pregnancy and their associations with maternal and child outcomes. Jean Golding and colleagues have published extensively on these findings.
Risk Factors
Previous mental health difficulties, a history of trauma or abuse, pregnancy loss or infertility history, a complicated pregnancy (physical health problems, high-risk classification), relationship difficulties, poor social support, and previous traumatic birth experiences all increase risk. Anxiety is not a sign of weakness or poor coping; it has specific risk factors and biological underpinnings, including the hormonal shifts of early pregnancy.
What Antenatal Anxiety Looks Like
Anxiety in pregnancy can take different forms. Generalised anxiety presents as persistent, hard-to-control worry about a wide range of pregnancy and non-pregnancy-related concerns. It is accompanied by physical symptoms: tension, sleep disturbance, fatigue, difficulty concentrating, irritability.
Specific anxiety about the baby's health – constant checking, repeated appointments-seeking, being unable to reassure oneself between scans – is common and can be severely distressing.
Health anxiety or hypochondria focused on the pregnancy can mean a woman interpreting every physical symptom as a sign of disaster.
Tocophobia is a specific, intense fear of childbirth that affects around 6-10% of pregnant women. It can be a primary phobia in women with no history of childbirth, or secondary, arising after a traumatic previous birth. Women with severe tocophobia may request caesarean birth as a result of their fear; NICE guidance indicates that a maternal request for caesarean should be considered on its merits with appropriate discussion. Helen Crowther and colleagues at the University of Nottingham have researched the prevalence and management of tocophobia in UK populations. Treatment with CBT-based interventions is effective in many cases.
Perinatal PTSD affects women who have experienced previous birth trauma, trauma during the current pregnancy, or who carry pre-existing PTSD from other trauma. It presents with intrusive re-experiencing, avoidance of reminders, and hypervigilance. It is treatable with trauma-focused CBT or EMDR (Eye Movement Desensitisation and Reprocessing).
Impact on the Baby
Prolonged maternal anxiety during pregnancy is associated with altered cortisol levels and changes in fetal neurodevelopmental programming. Vivette Glover at Imperial College London has led research showing associations between high maternal anxiety in pregnancy and behavioural and emotional difficulties in the child, particularly at age 4-5 years. The mechanism involves glucocorticoid exposure and its effects on fetal brain development. This is not a reason to add to a pregnant person's anxiety by blaming them; it is a reason to ensure that anxiety is treated rather than tolerated.
Treatment
NICE guideline PH25 and associated perinatal mental health guidance recommend that anxiety in pregnancy be assessed and treated with the same priority as depression. Assessment with validated tools (the GAD-7, Edinburgh Postnatal Depression Scale) is recommended at the booking appointment and at other contacts.
CBT is the first-line psychological treatment for anxiety in pregnancy. Mindfulness-based cognitive therapy (MBCT) has evidence supporting its effectiveness in reducing anxiety symptoms in pregnancy. NHS Talking Therapies (IAPT) services provide CBT and support, with some services having specialist perinatal pathways.
Medication: sertraline is the SSRI with the largest perinatal evidence base and is commonly used when medication is indicated. The risk-benefit balance – weighing the risks of untreated anxiety against the risks of medication – needs to be made individually with a prescriber. The notion that no medication is always safer than medication during pregnancy is not supported by evidence; untreated psychiatric illness carries its own risks.
Perinatal mental health teams provide specialist support for women with complex or severe antenatal mental health difficulties. PANDAS Foundation UK (pandasfoundation.org.uk) provides support specifically for perinatal anxiety and depression.
Key Takeaways
Anxiety is the most common mental health problem in pregnancy, affecting around 15-20% of pregnant women, and is at least as common as postnatal depression. Antenatal anxiety is a significant risk factor for postnatal depression and is associated with adverse outcomes for the baby. It is under-identified and under-treated because worry in pregnancy is culturally normalised. Tocophobia (pathological fear of childbirth) affects around 6-10% of pregnant women and is treatable. NICE guidelines recommend that anxiety in pregnancy should be assessed and treated with the same urgency as depression. CBT and mindfulness-based approaches are evidence-based; medication may be needed and can be used safely with appropriate guidance.
