Panic Disorder: Symptoms, Causes, and Support in the UK

Panic disorder is a type of anxiety disorder where you experience regular and recurring panic attacks, often without an obvious trigger. While many people may experience one or two panic attacks in their lifetime during particularly stressful periods, panic disorder is diagnosed when these attacks become frequent and are accompanied by a persistent worry about having further episodes.

In the UK, panic disorder affects approximately 2 in 100 people. It can be a debilitating condition that leads to avoidant behaviour, as individuals may stop visiting certain places or engaging in activities where they fear an attack might occur. However, it is important to remember that panic disorder is a recognised medical condition and effective support is available through the NHS and private providers.

The core feature of panic disorder is the panic attack—a sudden intense surge of fear or discomfort that reaches a peak within minutes. Because the physical symptoms are so intense, many people mistake a panic attack for a heart attack or another medical emergency.

Common physical symptoms include:

• Palpitations or a racing heartbeat
• Shortness of breath or a feeling of choking
• Chest pain or discomfort
• Trembling or shaking
• Excessive sweating and chills
• Nausea or stomach upset
• Dizziness, lightheadedness, or feeling faint
• Numbness or tingling sensations (paresthesia)

Psychological symptoms often involve a sense of impending doom, a fear of losing control, or a fear of dying. You may also experience 'derealisation' (feeling like the world around you isn't real) or 'depersonalisation' (feeling detached from yourself).

The exact cause of panic disorder is not fully understood, but it is likely a combination of biological, psychological, and environmental factors. Some people may have a genetic predisposition to anxiety, while others may develop the condition following a period of significant life stress, such as a bereavement or a major career change.

In some cases, the 'fear of fear' becomes the primary trigger. A person becomes so sensitised to their body's physical sensations that a slight increase in heart rate (perhaps from climbing stairs or drinking caffeine) is interpreted as the start of a panic attack, which then triggers the very attack they were afraid of. Substance use, including excessive caffeine or alcohol, can also exacerbate symptoms for those prone to panic.

If you are diagnosed with panic disorder, there are several evidence-based treatments recommended by the National Institute for Health and Care Excellence (NICE). The goal of treatment is to reduce the frequency of attacks and ease the severity of symptoms.

• Cognitive Behavioural Therapy (CBT): This is often the first-line treatment. CBT helps you identify and change the thought patterns that lead to panic. You learn that the physical sensations of panic are not dangerous.
• Applied Relaxation: This involves learning specific techniques to relax your muscles quickly during times of high tension.
• Medication: If therapy alone is not sufficient, a GP may prescribe Selective Serotonin Reuptake Inhibitors (SSRIs), which are commonly used for anxiety and depression. These are not addictive but require several weeks to become effective.
• Self-Help: Using NHS-approved workbooks or apps can be an effective way to manage mild symptoms.

Managing a panic attack in the moment requires focus and practice. One of the most effective methods is 'square breathing' or 'box breathing'—inhaling for four seconds, holding for four, exhaling for four, and holding for four. This helps regulate the carbon dioxide levels in your blood, which often drop during hyperventilation.

It is also helpful to stay where you are during an attack if it is safe to do so. If you run away from the situation, you reinforce the belief that the situation was dangerous. By staying, you allow your body's 'fight or flight' response to naturally subside, proving to your brain that the danger was internal rather than external. Grounding techniques, such as the 5-4-3-2-1 method (identifying 5 things you can see, 4 you can touch, etc.), can also help bring your focus back to the present moment.

If panic attacks are beginning to interfere with your daily life, your work, or your relationships, it is important to speak with a healthcare professional. An online GP can provide a safe, confidential space to discuss your symptoms and help differentiate between panic disorder and other physical health conditions.

A GP consultation is a vital first step in accessing mental health support. They can review your medical history, discuss the frequency of your attacks, and refer you to psychological therapies or prescribe medication if appropriate. They can also provide a fit note if your condition is currently preventing you from working. Seeking help early can prevent panic disorder from developing into agoraphobia (a fear of being in situations where escape might be difficult).
