When to call

This is a psychiatric emergency. Ask for an urgent assessment the same day — not an appointment next week. The NHS instruction is exact: "See a GP immediately if you think you, or someone you know, may have developed symptoms of postpartum psychosis. You should request an urgent assessment on the same day." The Royal College of Psychiatrists says the same in one line: "It is a psychiatric emergency — you should seek help as quickly as possible."

If you cannot speak to a GP, call NHS 111 (or your local urgent mental health line). The NHS says to use 111 "if you cannot speak to a GP or do not know what to do next."

Call your local emergency number (999 in the UK and Ireland, 911 in the US and Canada, 000 in Australia, 111 in New Zealand) or go to an emergency department if there is any danger of imminent harm to the mother or the baby. The NHS wording: "Go to A&E or call 999 if you think you, or someone you know, may be in danger of imminent harm."

If you are a partner, parent or friend, act on what you can see. The NHS warns: "if you have postpartum psychosis, you may not realise you're ill. Your partner, family or friends may spot the signs and have to take action." Action on Postpartum Psychosis puts the reason bluntly: "PP can get worse very quickly and should always be considered as a medical emergency."

You will not be wasting anyone's time. Postpartum psychosis is treatable and most women recover fully, but the speed of the response changes how bad it gets.

What postpartum psychosis is

The RCPsych definition: "Postpartum psychosis (or puerperal psychosis) is a severe mental illness. It starts suddenly in the days, or weeks, after having a baby. Symptoms vary, and can change rapidly. They can include high mood (mania), depression, confusion, hallucinations and delusions."

It is rare. The RCPsych says "about 1 in every 1000 women (0.1%) who have a baby will have a postpartum psychosis." It is also not anyone's fault: "Postpartum psychosis is not your fault, and is not caused by anything you or your partner have done." And it can arrive without warning — it "can happen to any woman and often occurs 'out of the blue', even if you have not been ill before."

When it happens

Early. The NHS: "Symptoms usually start suddenly within the first 2 weeks after giving birth - often within hours or days of giving birth, though more rarely, they can develop several weeks after the baby is born." The RCPsych agrees: "Usually in the first two weeks after birth. Often symptoms begin in the first few days."

That two-week window is the single most useful fact on this page. A dramatic change in the first fortnight is not the baby blues running long.

The symptoms

The RCPsych list includes: feeling "high", manic or on top of the world; low mood and tearfulness; anxiety or irritability; rapid changes in mood; severe confusion; being restless and agitated; racing thoughts; behaviour that is out of character; being far more talkative and active than usual, or very withdrawn; finding it hard to sleep or not wanting to sleep; losing inhibitions; feeling paranoid, suspicious or fearful; feeling as if you are in a dream world; delusions ("odd thoughts or beliefs that are unlikely to be true"); and hallucinations, where "you see, hear, feel or smell things that aren't really there."

The NHS groups them as mania, low mood, a mixture of both or rapidly changing moods, plus hallucinations, delusions and confusion. Both sources stress how fast the picture changes — "from hour to hour and from one day to the next," in the RCPsych's words.

Who is at higher risk

The RCPsych names bipolar disorder type I, schizoaffective disorder, a previous episode of postpartum psychosis, and a mother or sister who has had it. Its published risk table is worth knowing if any of that applies to you:

No history of mental illness and no family history: about 1 in 1000.
No history of mental illness, but a mother or sister who had postpartum psychosis: about 3 in 100.
Bipolar type I or schizoaffective disorder, first pregnancy, no family history: about 1 in 5.
Previous postpartum psychosis: about 1 in 2.

NICE CG192 turns this into a clinical instruction: "If a woman has any past or present severe mental illness or there is a family history of severe perinatal mental illness in a first-degree relative, be alert for possible symptoms of postpartum psychosis in the first 2 weeks after childbirth." If you are in one of those groups, the RCPsych advises a pre-birth planning meeting around 32 weeks so that everyone involved knows the plan before the baby arrives.

What happens when you ask for help

NICE sets the clock: "If a woman has sudden onset of symptoms suggesting postpartum psychosis, refer her to a secondary mental health service (preferably a specialist perinatal mental health service) for immediate assessment (within 4 hours of referral)." Four hours — that is the standard you are entitled to.

Treatment usually means hospital. The NHS says admission is normally "in a specialist psychiatric unit called a mother and baby unit (MBU)" where you and your baby stay together, although a general psychiatric ward may be used first if no MBU bed is available. Medication is typically part of treatment; Action on Postpartum Psychosis notes that people affected will "probably need to be given medication and admitted to hospital."

Recovery

The NHS gives the timeline honestly: "The most severe symptoms tend to last 2 to 12 weeks, and it can take 6 to 12 months or more to recover completely." Full recovery is the normal outcome with treatment. The RCPsych: "It can last several weeks or longer — but you will usually recover fully."

Support

Action on Postpartum Psychosis (app-network.org) is the UK charity specifically for this illness, with peer support from women who have been through it and a moderated forum. PANDAS Foundation supports families affected by perinatal mental illness more broadly. Samaritans are free on 116 123 in the UK and Ireland, day or night. In the US, Postpartum Support International's helpline is 1-800-944-4773, and 988 reaches the Suicide and Crisis Lifeline.
