What can cause anxiety?

There are many factors that can trigger an anxiety disorder and they can be different for each of us. They include:

  • Persistent/extreme stress
  • Physical factors (e.g. thyroid problems, respiratory problems)
  • Your environment
  • Your life experiences
  • Your genes
  • Biochemical imbalances (changes in the levels of chemical messengers in the brain)

Knowing the cause of an anxiety disorder doesn’t help much in dealing with the day to day problems that arise as a result of the disorder but it can be reassuring to know that there are factors out of their control that may have contributed to their current health.
