Condition : Anxiety
What is anxiety?
Anxiety is a natural response to threats that causes you to feel worried, nervous, concerned, or uneasy.
When anxiety becomes difficult to control and affects your everyday life, then you may have an anxiety disorder. Panic disorders and phobias (fear of something specific) are types of anxiety disorder.
Examples of anxiety disorders include:
- generalised anxiety disorder (GAD) – often feeling very anxious about lots of different things
- social anxiety disorder (also known as social phobia) – a fear of social situations
- selective mutism – being unable to speak in certain social situations
- agoraphobia – a fear of being in situations, such as on a bus or in a crowd, where help or an easy escape might not be available
- body dysmorphic disorder (BDD) – worrying about flaws in your appearance
It’s common to have more than one type of anxiety disorder at the same time.
Alongside feelings of stress or worry, common symptoms of anxiety disorders include:
- faster, irregular, or more noticeable heartbeat (palpitations)
- feeling lightheaded or dizzy
- stomach problems
- chest pain
- trembling or shaking
- numbness or pins and needles
- feeling tense, nervous, or irritable
- problems with concentration
- getting tired easily
- difficulty sleeping (insomnia)
- being unable to relax or enjoy leisure activities
- avoiding situations that create anxiety
- panic attacks (sudden, intense episodes of anxiety and fear where you may have a racing heartbeat and feel faint, sick, or breathless)
People with anxiety often also have, or go on to develop, other mental health conditions, such as depression and eating disorders.
Anxiety is also linked with obsessive compulsive disorder (OCD), which is when you can’t stop unpleasant thoughts and feel you need to do a particular action to get temporary relief from the feelings those thoughts bring.

What causes anxiety?
We have evolved to feel anxious when we’re in danger so that our ‘fight, flight, or freeze’ response will be triggered to protect us. This response involves the release of hormones which make you feel more alert and increase your heart rate so blood can quickly get where it’s needed most (to enable you to run away or fight).
If you have an anxiety disorder, this response is being triggered at times when there is no real threat, and the feelings it brings are very strong or last for a long time.
It’s not fully understood what causes anxiety disorders, though it’s believed that a mixture of things can trigger them, including:
- an event that caused a lot of stress
- genetics (having a close family member who has an anxiety disorder)
- an imbalance of neurotransmitters (chemical messengers) in the brain
