Postpartum depression: baby blues vs depression, causes and what helps

Postpartum depression, also called postnatal depression, is a common form of depression that can happen after having a baby, and it usually gets better with treatment (NHS, 2026). A mother is not to blame for it: it is not caused by anything she has or has not done (NIMH, 2023). Even in studies limited to healthy mothers with no history of depression who had healthy babies, 12% developed depression after birth (Shorey et al., 2018). The WHO’s International Classification of Diseases (ICD-11) adds a “pregnancy and childbirth” code to depression that starts in pregnancy or within about 6 weeks of birth (WHO, 2024), but symptoms can begin in pregnancy or at any time up to a year after birth (NHS, 2026).

The WHO estimates that about 1 in 10 women in high-income countries, and 1 in 5 in low- and middle-income countries, experience anxiety or depression in pregnancy or the year after birth (WHO, 2022). An analysis of 565 studies from 80 countries and regions found postpartum depression in 17.22% of women who had given birth, but most studies used questionnaire scores; in the 5 studies that diagnosed it with a structured clinical interview (SCID), the figure was lower, at 10.11% (Wang et al., 2021). Rates also vary widely between countries, from 3% to 38% (Hahn-Holbrook et al., 2018). In an analysis of 123 Japanese studies, the figure about 1 month after birth was 14.3% (Tokumitsu et al., 2020a).

In Korea’s 2024 postnatal care survey of 3,221 women who gave birth in 2023, 68.5% said they had felt low after giving birth, but this was a self-reported feeling, not a diagnosis; the ministry reported that 6.8% had actually been diagnosed with postpartum depression (Ministry of Health and Welfare, 2025a). In Korean health insurance data on 81,447 women who gave birth in 2004-2013, only 0.82% had a record of treatment for postpartum depression within 6 months of birth (Nam et al., 2017). Far fewer people may be treated than are affected.

mind.io does not offer a postpartum depression test. If low mood lasts more than 2 weeks, see depression symptoms as well. If you have thoughts of harming yourself, please do not carry them alone. Reach out to a crisis line right away: call or text 988 in the US and Canada, call Samaritans on 116 123 in the UK and Ireland, or find a line at findahelpline.com elsewhere. If you are in immediate danger, contact your local emergency services.

Feeling down, anxious or irritable for a few days after giving birth is very common and usually passes within 2 weeks; this is called the baby blues (NHS, 2026). France’s national health insurance says 50% to 80% of women who give birth experience it, that it starts on day 2 to 5 after birth and disappears completely within 2 weeks, and that it does not need medicine (Assurance Maladie, 2025a). The WHO’s classification likewise does not count the mild, passing low mood soon after birth as a diagnosis (WHO, 2024).

Postnatal depression may begin like the baby blues, but it is more intense, lasts longer and makes daily life, including caring for the baby, harder (WHO, 2024). Symptoms can include low mood, finding it hard to enjoy anything, feeling hopeless or unable to cope, feeling guilty or like a bad parent, constant anxiety and worry, difficulty sleeping even when you get time to rest, difficulty concentrating or making decisions, difficulty bonding with your baby, and thoughts of harming yourself or your baby. It is important to get help even if you only have some of these (NHS, 2026). Not being able to sleep even when the baby is asleep, night after night, may be more than ordinary tiredness from caring for a newborn (NIMH, 2023).

Anxiety is common after birth too. In an analysis of 102 studies, 15.0% of women had anxiety symptoms 1 to 24 weeks after birth, and 9.9% had an anxiety disorder (Dennis et al., 2017). Worries that the baby will be hurt, and unwanted thoughts about possible harm, are also common after birth; they are not a disorder in themselves, and are diagnosed as a pregnancy-related mental health condition when they persist, cause a lot of distress and get in the way of daily life (WHO, 2024). Unwanted thoughts are covered in the FAQ of OCD: what helps, and anxiety in anxiety symptoms.

Postpartum psychosis is rare but an emergency, affecting around 1 in 1,000 mothers after giving birth (NHS, 2023); population-based studies found an incidence of 0.89 to 2.6 per 1,000 (VanderKruik et al., 2017). It usually starts suddenly within the first 2 weeks after birth, and the mother may see or hear things that are not there, firmly believe things that are not true, feel very high or have rapidly changing moods, or seem very confused. She may not realise she is ill, so partners, family or friends may need to spot the signs and contact emergency services straight away. Most people make a full recovery with the right treatment (NHS, 2023).

The exact cause of postnatal depression is not known; the stress of caring for a new baby, lack of sleep and hormonal changes in pregnancy may all be involved (NHS, 2026). Sensitivity to hormone changes is one factor, but the risk factors are mostly similar to those for depression in general (O’Hara & McCabe, 2013). Pooling many reviews, the strongest risk factors were depression during pregnancy and current abuse, and high life stress, lack of support and dissatisfaction with the relationship were also common (Hutchens & Kearney, 2020). In data on 3,127 Korean women who gave birth in 2020, depression during pregnancy was also the strongest predictor, and the risk was slightly lower the more the father was involved in childcare (Cho & Lee, 2025). Having risk factors does not mean it will happen, and having none does not mean it cannot.

The risk is higher if you or your family have had depression or bipolar disorder, or if you had depression in a previous pregnancy (NIMH, 2023). In an analysis of 4,023 women with bipolar disorder or a previous postpartum psychosis (5,700 deliveries), 35% relapsed after birth (Wesseloo et al., 2016). In that case, tell your doctor before pregnancy and prepare for the time after birth together; with the right care, the risk can be reduced (NHS, 2023). Bipolar disorder is covered in bipolar disorder.

Fathers and partners can also have depression after a baby is born (NHS, 2026). In an analysis of 74 studies, 8.4% of fathers had depression during pregnancy or after birth (Cameron et al., 2016), and fathers’ depression was moderately linked to mothers’ depression (Paulson & Bazemore, 2010). An analysis of studies of Japanese fathers also found postpartum depression in about 10%, most often 3 to 6 months after birth (Tokumitsu et al., 2020b). The WHO notes that partners and other caregivers often feel they have no right to support (WHO, 2022).

Postnatal depression usually gets better in 3 to 6 months, but it can sometimes last much longer, and it is more likely to get better with treatment (NHS, 2026). Some studies link postnatal depression with effects on children’s emotional development, but these are not inevitable: treating the parent’s depression so that it does not last, and support from a partner and others with caregiving, matter (Stein et al., 2014). In an analysis of 47 trials treating depressed mothers with psychological therapy, mothers’ depression eased, and mother-child interaction and children’s mental health probably improved too, by a small but significant amount (Cuijpers et al., 2026).

Cognitive behavioural therapy (CBT) and interpersonal therapy are evidence-based treatments (NIMH, 2023). In an analysis of 43 trials (6,270 people) of psychological therapy for depression in pregnancy or after birth, therapy had a moderate effect on depression (effect size 0.67, or 0.53 after adjusting for publication bias) that lasted 6 to 12 months; CBT was the most studied (Cuijpers et al., 2023). UK guidelines suggest considering facilitated self-help for mild to moderate depression, and for moderate or severe depression a high-intensity psychological therapy such as CBT, an antidepressant if the woman prefers medicine or therapy has not helped, or both together (NICE, 2014).

Prevention is possible too. When pregnant and postpartum women at higher risk, for example with a history of depression or some current depressive symptoms, received counselling such as CBT or interpersonal therapy, the chance of developing perinatal depression fell by about 39% (USPSTF, 2019). A Cochrane analysis of prevention trials also found about a 22% lower risk in women who received counselling or support, with intensive home visits by nurses or midwives, telephone support from mothers who had been through it, and interpersonal therapy especially promising (Dennis & Dowswell, 2013). In a Canadian trial (701 women) in which mothers who had recovered from postnatal depression gave telephone support to high-risk mothers in the first 2 weeks after birth, 14% had high depression scores at 12 weeks, compared with 25% without this support (Dennis et al., 2009).

Most women can be helped with psychosocial support and psychological therapy, but medicine may be needed for moderate to severe symptoms, when psychological therapy has not helped, or with bipolar disorder or psychosis (WHO, 2022). In a Cochrane analysis of 11 trials of antidepressants for postnatal depression, 55% of women on SSRIs improved versus 43% on placebo, suggesting a possible benefit, but the certainty of the evidence was low or very low (Brown et al., 2021). The general effects and precautions of antidepressants are covered in antidepressants and psychiatric medication.

If you are breastfeeding, tell your doctor. The NHS says many antidepressants are safe to use while breastfeeding (NHS, 2026), while UK guidelines note that safety data during breastfeeding are limited, so benefits and risks should be weighed, and the baby watched for side effects if the mother takes medicine while breastfeeding (NICE, 2014). Each woman should be supported in the feeding choice that suits her and her family (NICE, 2014). Talk to your doctor before starting or stopping any medicine.

Postpartum psychosis is treated with medicines such as antipsychotics or mood stabilisers (NHS, 2023) and is a psychiatric emergency that needs hospital care (NIMH, 2023). There is not enough evidence that supplements such as omega-3 prevent postnatal depression (Miller et al., 2013).

Talk about your feelings to a friend, family member or health professional, and ask for help with practical things such as shopping, chores and childcare. Try to get regular exercise, even just a short daily walk, get as much sleep and rest as you can, and make time for things you enjoy, however small. A local parent and baby group can help too. Do not use alcohol or illegal drugs to manage your feelings (NHS, 2026). In analyses of exercise trials after birth, exercise reduced depressive symptoms a little, but results varied widely and the quality of evidence was low (Pritchett et al., 2017; Carter et al., 2019). Think of gentle activity that suits your body as something to do alongside treatment, not instead of it.

Partners and family may be the first to notice changes. Encourage a visit to a doctor, go to appointments together, listen, and share the baby care and housework (NIMH, 2023). France’s national health insurance advises protecting the mother’s sleep, involving the partner or someone close in handling the nights, avoiding isolation, and no alcohol while breastfeeding (Assurance Maladie, 2025b). If you cannot sleep even when the baby is asleep, night after night, see insomnia: what helps too.

In Korea’s 2024 postnatal care survey, mothers most often named their spouse (57.8%) as the person who eased their low mood after birth, but 23.8% said they had received no help (Ministry of Health and Welfare, 2025a). Korea’s Mother and Child Health Act includes the spouse in counselling and education on depression in pregnancy and after birth (Mother and Child Health Act, Article 10-5). How to ask about suicidal thoughts and how to support someone are covered in depression: what helps.

If postpartum psychosis is suspected, for example seeing or hearing things that are not there, firmly believing things that are not true, or seeming very high or confused, or if, unlike unwanted intrusive thoughts, you really want to harm your baby or have a plan to harm yourself now, or feel you cannot keep your baby safe, contact your local emergency services now (NHS, 2023; NIMH, 2023). If low mood or anxiety continues or gets worse more than 2 weeks after birth, see a doctor even if you only have some of the symptoms. You may be scared that your baby will be taken away if you ask for help, but this is very rare, and your care team will help you care for your baby (NHS, 2026).

If violence is still going on, safety comes first: in immediate danger, call your local emergency number; in the US the National Domestic Violence Hotline is 1-800-799-7233 and in the UK the National Domestic Abuse Helpline is 0808 2000 247. Outside Korea, talk to your family doctor, midwife or health visitor. In Korea, you can talk to an obstetrician or a psychiatrist, and public health centres offer postpartum depression screening and refer you to counselling services (Ministry of Health and Welfare, 2022). Depression and anxiety around pregnancy and birth can also be discussed at the central and regional counselling centres for infertility and pregnancy (Ministry of Health and Welfare, 2024; Mother and Child Health Act, Article 11-4), and the mental health crisis line 1577-0199 (24 hours) connects you to a nearby mental health welfare centre (Ministry of Health and Welfare, 2025b). The conditions for the 2026 counselling voucher are in depression: what helps. mind.io does not offer a postpartum depression test; the depression check-in (PHQ-9) looks at depressive symptoms over the past 2 weeks but does not replace a diagnosis.

Up to 20% of women with mental health conditions in pregnancy or after birth have suicidal thoughts or self-harm (WHO, 2022). In France, about 1 in 20 women (5.4%) reported suicidal thoughts 2 months after giving birth (Doncarli et al., 2023). If you have thoughts of harming yourself, please do not carry them alone. Reach out to a crisis line right away: call or text 988 in the US and Canada, call Samaritans on 116 123 in the UK and Ireland, or find a line at findahelpline.com elsewhere. If you are in immediate danger, contact your local emergency services.

Q. Is there a self-test for postpartum depression? A. mind.io does not offer one. Health centres and hospitals sometimes use questionnaires to check mood, and UK guidelines suggest using such questionnaires (the EPDS or PHQ-9) as part of a full assessment (NICE, 2014). A depression check-in (PHQ-9) score alone cannot diagnose postnatal depression.

Q. Can fathers get postnatal depression? A. Yes. In a pooled analysis, 8.4% of fathers had depression during pregnancy or after birth (Cameron et al., 2016), and fathers were more often depressed when mothers were (Paulson & Bazemore, 2010). Fathers can get help too, so do not just put up with it.

Q. I keep having distressing thoughts of harming my baby. A. Unwanted thoughts like these are common after birth and are not a disorder in themselves; they are diagnosed as a pregnancy-related mental health condition when they persist, cause a lot of distress and get in the way of daily life (WHO, 2024). If the thoughts are very distressing or you find yourself avoiding your baby, talk to your doctor or midwife. More is in the FAQ of OCD: what helps. But if you feel confused, see or hear things that are not there or feel completely unlike yourself, or if you really want to harm your baby or feel you cannot keep your baby safe, contact your local emergency services now.

Q. Can I take medicine while breastfeeding? A. Many antidepressants can be used while breastfeeding (NHS, 2026), but safety data during breastfeeding are limited, so you and your doctor weigh the benefits and risks (NICE, 2014). Always tell your doctor you are breastfeeding, and do not stop medicine on your own.

Q. How long does postpartum depression last? A. It usually gets better in 3 to 6 months, but it can last longer, and it is more likely to get better with treatment (NHS, 2026). Without proper treatment, it can last more than a year (National Mental Health Information Portal, 2021).

Q. Will it happen again if I have another baby? A. The risk is higher if you had depression in a previous pregnancy (NIMH, 2023). After postpartum psychosis, there is about a 1 in 2 chance of another episode after a future birth, but the right care can reduce the risk (NHS, 2023). Talk to your doctor when you start planning a pregnancy.

Q. It’s so hard I’m having thoughts of harming myself. A. Please do not carry them alone. Reach out to a crisis line right away: call or text 988 in the US and Canada, call Samaritans on 116 123 in the UK and Ireland, or find a line at findahelpline.com elsewhere. If you are in immediate danger, contact your local emergency services.
