Postpartum psychosis is not just hormones. Hormonal changes after birth may play a part, but they are not the whole story. 

It is a serious psychiatric emergency that can develop suddenly after having a baby.

What is postpartum psychosis? 

Postpartum psychosis affects around 1 in 1,000 mothers. It usually starts in the first two weeks after birth, often within hours or days.

A woman may experience: 

• Hallucinations or delusions
• Severe confusion
• A mood that changes suddenly and intensely
• Not sleeping even when the baby is asleep
• Saying things that do not make sense to people who know her

This is not the baby blues, and it is not simply having a bad week. 

Are hormones involved?

Yes, but hormones are only part of the picture.

After birth, estrogen and prolactin levels shift sharply. At the same time, there may be: 

1. Stress from the birth
2. Severe sleep loss
3. An underlying vulnerability that increases the risk of developing the condition

For someone vulnerable, these changes can contribute to a shift into mania or a break with reality. 

So, calling postpartum psychosis “just hormones” can minimize how serious the illness is. 

Who is more at risk? 

Women who have bipolar disorder have the highest risk. Around 2 in 10 women with bipolar disorder may go on to develop postpartum psychosis. 

Other risks include: 

• Having had postpartum psychosis in a previous pregnancy
• Having schizophrenia
• Having a family history of postpartum psychosis

After one episode of postpartum psychosis, the chance of another episode in a future birth is around 2 in 10 women, or 50%.

What should you do if you are worried?  

Postpartum psychosis needs an urgent same-day assessment. 

If you or someone you know has symptoms, contact a:

• GP or family doctor
• Midwife
• Health visitor

If there is a danger of imminent harm, call 999 or 911 or go to the emergency department. 

One important point is that a woman experiencing postpartum psychosis may not realise that she is ill. Family members may therefore need to act on her behalf. 

Planning ahead 

If you are pregnant and have: 

• Bipolar disorder
• Schizophrenia
• A previous episode of postpartum psychosis
• A strong family history

Tell your doctor early. 

A pre-birth planning meeting in the early third trimester can help you have a written plan for the birth, including who to call, what to watch for, and where to go for help.

Key takeaway

Postpartum psychosis is not just hormones. Hormonal changes can be part of the trigger, alongside factors such as severe sleep loss, birth-related stress, and individual vulnerability. It is a serious condition, but many women make a full or substantial recovery with treatment and support.
