Pregnancy and childbirth are normal life events and can bring a range of emotions. However, throughout this journey, these emotions can be complicated by disturbances in mental wellbeing, described as ‘perinatal mental health’ (PMH).

PMH is the overarching term for mental health during pregnancy and the first postnatal year (although some areas will continue to provide support beyond the first year). It can be characterised by either an existing mental health issue or a condition that arises/exacerbated during pregnancy or is related to pregnancy. In severe cases, a mother's distress can become so overwhelming, potentially leading to suicide. See: .

According to the NHS, perinatal mental illness affects up to 27% of new and expectant mums in the UK and covers a wide range of conditions. Elsewhere, evidence from the World Health Organisation (WHO) suggests that worldwide about 10% of pregnant women and 13% of women who have just given birth experience a mental disorder, primarily depression. In developing countries this figure is even higher, for example . 

A mental health condition is considered a disability if it has a long-term effect on normal day-to-day activity. This is defined under the . The condition is ‘long term’ if it lasts, or is likely to last, 12 months. ‘Normal day-to-day activity’ is defined as something that is done regularly in a normal day. This includes things like using a computer, working set times or interacting with people.

Severe mental illness support during pregnancy

In 2021, the charity Tommy’s partnered with Kings College London (KCL), NHS England (NHSE) and Public Health England (PHE) (since been replaced by the UK Health Security Agency and Office for Health Improvement and Disparities) to produce a suite of mental illness resources. These resources aimed to support women with a severe mental illness (SMI) to make informed decisions about when to get pregnant, what to watch out for and how to treat their condition during and after pregnancy.

The resources include a new online information and support hub for anyone with a SMI planning a pregnancy, as well as practical guidance for the frontline health care professionals who support them. Tommy’s also offers a  Planning for Pregnancy tool so users with severe mental illness get specific tailored information and support. 

Factors that impact on mental wellbeing include:

• feelings, thoughts and actions
• age can be a factor; in particular, young mums
• physical health, wellness and experiences
• education and employment
• social/family relationships/domestic abuse 
• economic and social circumstances
• lifestyle choices
• culture and ethnic background
• gender and sexuality
• use of drugs or alcohol
• past experiences, such as abuse, neglect, and other adverse childhood experiences, as well as experiences from being in care.
• any dependents, for example a child or elderly relative.

Mental health issues during pregnancy and post birth could include:

1. Generalised anxiety disorder (GAD), social anxiety, panic disorder, obsessive-compulsive disorder (OCD)

2. Severe mental health issues such as:

• depression
• psychosis and bipolar disorders
• personality disorders
• tokophobia
• PTSD
• eating disorders.

3. Some developmental conditions are more likely to have mental health problems including: 

• autistic spectrum disorders
• attention deficit hyperactivity disorder.

4. Suicide and self-harm

PMH describes mental health during pregnancy and the first postnatal year. This could be characterised by an existing mental health issue or a condition that arises during pregnancy, including antenatal depression and postpartum.

Suicide continues to be the leading cause of direct maternal death between 6 weeks and 12 months after birth, accounting for a staggering 39% of deaths in this period. Some 37% of the women who died were known to have a previous or existing mental health condition.

• Do you have new feelings or thoughts that you have never had before, which make you disturbed or anxious? 
• Are you experiencing thoughts of suicide or harming yourself in violent ways?

• Do you feel you are getting worse?  

During pregnancy, women may also be subject to specific mental health issues, generally identified as antenatal depression.

Antenatal depression can occur at any stage during pregnancy. There is a range of support available, including self-help, psychological therapy and medication to manage symptoms. The NHS provides further information on this: . If antenatal depression is not treated symptoms can get worse and may continue after the baby is born (‘postnatal depression’).

Postnatal (or puerperal) mental health issues include three main presentations:

• Maternity blues: Normally occurs around days three to four and affects 80% of women.
• Postnatal depression: Affects 10% of women.
• Puerperal psychosis: Rare but severe form of psychiatric illness.

Continuity of care is a key component of maternity care, and care for mental wellbeing. These should include:

• identify that there is an issue
• diagnosis
• early intervention
• appropriate care
• aftercare. 

NICE recommends asking Whooley questions which are:

• “During the past month, have you often been bothered by feeling down, depressed or hopeless?”
• “During the last month, have you often been bothered by having little interest or pleasure in doing things?”

Also consider asking about anxiety using the :

• Over the last 2 weeks, how often have you been bothered by feeling nervous, anxious or on edge?
• Over the last 2 weeks, how often have you been bothered by not being able to stop or control worrying?

If a woman responds positively to either of the depression identification questions, is at risk of developing a mental health problem, or there is clinical concern, consider:

• Using the or the as part of a full assessment or
• Referring the woman to her GP or, if a severe mental health problem is suspected, to a mental health professional.

When asking a woman ‘how are you feeling?' consider asking supplementary questions such as:

• How could you take time to look after yourself, even just a few minutes a day?
• How are you coping?
• Would you say you are feeling low?
• How are you sleeping?
• How often are you eating and how is your appetite in general?
• Would you say you are tearful, angry and/or anxious?
• Do you have concerns about your emotional wellbeing and your mental health?
• Who could you talk to about your concerns and what impact is this having? (Here you can suggest local groups, especially if the mum has no trusted family or friends to call upon for support.)

Specialist teams in Scotland

Scottish Government investment in perinatal mental health (PMH) since 2019 has led to the expansion of specialist services throughout Scotland, meaning many more women, babies, and families can benefit from this critical care. While this is good news, continued investment to ensure sustainable services and quality standards are met must be a priority. 

There are two Mother and Baby Units (MBUs), both located in Central Scotland.
