Quick answer
What is Postpartum psychosis?
Postpartum (puerperal) psychosis is a rare but serious mental illness that can develop in the days or weeks after having a baby, often coming on suddenly. It is different from, and much more serious than, the common "baby blues" or postnatal depression.
- How it is treated: Postpartum psychosis is a medical emergency and needs urgent specialist assessment and treatment, usually in hospital — ideally in a specialist mother and baby unit, which allows the mother and baby to stay together while she is treated.
- Self-care: This is an emergency requiring urgent treatment rather than self-management.
- When to seek help: Seek urgent help immediately if a new mother develops confusion, a rapidly changing mood, or loses contact with reality (delusions or hallucinations) — contact the GP, maternity or mental health crisis team urgently, or call 999.
What it is
Postpartum (puerperal) psychosis is a rare but serious mental illness that can develop in the days or weeks after having a baby, often coming on suddenly. It is different from, and much more serious than, the common "baby blues" or postnatal depression. Symptoms can include a rapidly changing mood (very high, very low, or fluctuating), confusion, restlessness, difficulty sleeping, and loss of contact with reality — such as strong false beliefs (delusions) or seeing or hearing things that are not there (hallucinations). Behaviour may be out of character. It is more likely in women with a personal or family history of bipolar disorder or previous postpartum psychosis, but can happen without warning. Because it can escalate quickly and, rarely, carries risks to the mother or baby, it is a psychiatric emergency needing urgent assessment and treatment.
How it is treated
Postpartum psychosis is a medical emergency and needs urgent specialist assessment and treatment, usually in hospital — ideally in a specialist mother and baby unit, which allows the mother and baby to stay together while she is treated. Treatment includes medication (such as antipsychotics, mood stabilisers, and sometimes other treatments) and close support, and most women make a full recovery, though it can take time. With prompt treatment the outlook is good. Because of the risk of recurrence, women who have had it, or who are at higher risk (for example with bipolar disorder), are offered careful planning and support around future pregnancies. Support for the whole family is important. The key message is that it is a treatable emergency, and prompt help leads to recovery.
