What is generalised anxiety disorder?

Generalised anxiety disorder (GAD) is a type of anxiety disorder where people have persistent worry. It affects their day-to-day life on an ongoing basis.

While it is normal for most people to feel anxious at times, in an anxiety disorder, symptoms are more severe and affect your everyday activities.

There are different types of anxiety disorders. Some involve worry or panic in certain situations or triggered by specific things. In generalised anxiety disorder, worry occurs most of the time and in many different situations. GAD can include prolonged worry that lasts for months over many, often minor, issues. It can affect sleep, energy and general daily life.

Anxiety can be mild, moderate, severe or panic level, depending on how badly the symptoms are affecting you.

  • Mild anxiety — can affect your functioning, but doesn't significantly affect your daily activities.
  • Moderate anxiety — affects you more than mild anxiety and you may feel that your level of worry is out of control often, but not every day.
  • Severe anxiety — negatively affects your quality of life, making it difficult to function properly. You may have physical symptoms of anxiety most of the time.
  • Panic-level anxiety — is characterised by fear, heart palpitations and fast breathing. This is considered a panic attack. They can be scary and significantly affect your wellbeing.
