If you look on social media, you’ll see plenty of mothers showing how “perfect” their lives are with their babies and children. But smiles and cuddles don’t always show the whole truth. 

While most of us know that having a baby comes with physical consequences for the mother, not all are aware that it can impact a woman’s mental health too, and, in rare cases, can lead to severe episodes of illness known as postpartum psychosis.

Postpartum psychosis is rarely talked about. When it appears in the news it is usually because it was not spotted in time or because, on rare and tragic occasions, a new mother has committed suicide or harmed their baby. It isn’t very often that mothers speak out about their experiences.

But, despite this lack of coverage, it is more common than you might think. This severe episode of mental illness affects one to two mothers in every 1000 births. It has a clear onset, days or weeks after childbirth. Symptoms during an episode are acute, and can change rapidly, within days or even hours. They may include high or low mood, confusion, abnormal beliefs, and hearing or seeing things that are not there. They are very different from the “baby blues” or postpartum depression.

Causes and circumstances

Research has shown that in around 50 percent of cases where postpartum psychosis happens the mother has an established history of severe mental illness. But women with no previous psychiatric history can experience postpartum psychosis too. Women with bipolar disorder are at a particularly high risk – around one in five go on to experience an episode of psychosis following childbirth. For these women, being pregnant for the first time, or reporting sleep loss as a usual trigger of manic episodes, is associated with having postpartum psychosis. In other cases, childbirth can trigger further bipolar episodes.

In a recent BBC documentary hosted by Louis Theroux, the “perfect storm” of events and circumstances that can lead to postpartum psychosis was mentioned – with hormones, breastfeeding, sleep changes, obstetric complications, previous history and genetics and adapting to new circumstances among them.

The mechanisms underlying why women experience postpartum psychosis are complex, however. And while we know about some of the links with other mental illnesses, we don’t yet understand the full range of other biological factors, nor how genetics and environmental factors can affect or cause women to experience it.

Unfortunately this also means that we don’t yet know much about how to predict who is going to have an episode either, and, more importantly, how can we prevent it. So far it is just history of bipolar disorder or postpartum psychosis that is the most established associated factor and so is used in clinics to identify those at higher risk.

Lack of support

Becoming unwell after having a baby can have a huge impact on the lives of women and their families, disrupting the relationship with the new child. As it is an emergency, women experiencing it will need to be admitted to hospital in the initial stages, ideally with their babies. An episode of postpartum psychosis can last from weeks to months, but despite its severity, with the right treatment, most women recover – sometimes within weeks – and go on to develop excellent relationships with their children.

To achieve this goal, we currently need women who have experienced postpartum psychosis and/or have bipolar disorder – especially those who are currently pregnant – to take part in our studies. By continuing our research we hope that we can develop better ways of predicting postpartum psychosis and improve treatment for mothers affected by it and other mental illnesses.
