What can cause PTSD?

The situations we find traumatic can vary from person to person. There are many different harmful or life-threatening events that might cause someone to develop PTSD. For example:

being involved in a car crash
being raped or sexually assaulted
being abused, harassed or bullied - including racism, sexism, homophobia, biphobia or transphobia, and other types of abuse targeting your identity
being kidnapped, held hostage or any event in which you fear for your life
experiencing violence, including military combat, a terrorist attack, or any violent assault
seeing other people hurt or killed, including in the course of your job (sometimes called secondary trauma)
doing a job where you repeatedly see or hear distressing things, such as working in the emergency services or armed forces
surviving a natural disaster, such as flooding, earthquakes or pandemics, such as the coronavirus pandemic
traumatic childbirth as a mother, or as a partner witnessing a traumatic birth
losing someone close to you in particularly upsetting circumstances
being sectioned or getting treatment in a mental health ward
being diagnosed with a life-threatening condition.

Evidence suggests that pandemics can cause psychological trauma. If you're looking for support during the coronavirus pandemic you can find more information on looking after your mental health in our coronavirus and mental health hub.

I was mugged then about a year later I was on the Tube when the police were trying to arrest someone who had a gun. In neither experience was I physically injured – although in the second one I thought I was going to die and that I was going to see lots of other people die.

Are some people more at risk of PTSD?

Some factors may make you more vulnerable to developing PTSD, or may make the problems you experience more severe, including:

experiencing repeated trauma
getting physically hurt or feeling pain
having little or no support from friends, family or professionals
dealing with extra stress at the same time, such as bereavement, money worries, racism, seeking asylum, homelessness or spending time in prison
previously experiencing anxiety or depression.

If you experienced trauma at an early age or you have experienced long-lasting or multiple traumas, you might be given a diagnosis of complex PTSD.

Racial trauma

The impact racism can have on your mind and body is sometimes described as racial trauma. There's no universal definition of racial trauma. Some researchers say that it should be included as part of PTSD. Others say that it should be separate from PTSD, to reflect the specific traumatic experiences and effects of racism.

But however you choose to define your experiences, it is always ok to ask for help with your mental health.

I was diagnosed by my GP with PTSD a few weeks after the death of my father who died very suddenly, following a family outing to the local pub for lunch. He collapsed in front of us and we had to administer CPR at the scene while waiting for the ambulance. He died later on the way to hospital.

Anyone can experience traumatic events, but you may be particularly likely to have experienced trauma if you:

work in a high-risk occupation, such as the emergency services or armed forces
are a refugee or asylum seeker
were taken into foster care.

Secondary trauma

If you experience symptoms of PTSD while supporting someone close to you who has experienced trauma, this is sometimes known as 'secondary trauma' or 'secondary traumatic stress'.

'Secondary' means that although the original (primary) trauma happened to someone else, the impact it's having in your life is traumatic for you. It doesn't mean it's any less significant than any other kind of PTSD, or any easier to deal with. Our page for friends and family has some tips on looking after yourself.

Repeatedly witnessing or hearing about traumatic events in the course of your job is also sometimes called 'secondary trauma', although this experience is increasingly thought of by professionals as an original (primary) trauma.
