Most people feel anxious from time to time. Before a job interview, during a difficult period, or when facing something uncertain. That kind of anxiety is a normal part of life. Adult anxiety disorders are different. They involve persistent, intense anxiety that does not go away when the situation changes, and that significantly affects how a person thinks, feels, and functions day to day.

Anxiety disorders are among the most common mental health conditions in the UK. According to the NHS, generalised anxiety disorder alone is a common long-term condition that causes people to feel anxious about a wide range of situations and issues, often most days, and can affect every area of daily life.

What Is an Anxiety Disorder?

An anxiety disorder is not simply feeling stressed or worried. It is a recognised clinical condition in which anxiety becomes persistent, disproportionate to the situation, and difficult to control without support.

The distinction matters. Everyday anxiety tends to be tied to a specific event and eases once that event passes. With an anxiety disorder, the anxiety is ongoing, harder to switch off, and tends to affect work, relationships, and quality of life in ways that are hard to manage alone.

What Are the Main Types of Adult Anxiety Disorder?

Anxiety disorders are not a single condition. The NHS recognises several distinct types, including generalised anxiety disorder, social anxiety, panic disorder, phobias, agoraphobia, and health anxiety. Each has its own particular characteristics, and it is common to experience more than one at the same time, or to have anxiety alongside depression.

Our guide to the different types of anxiety disorders explains what each one involves and how they differ.

What Causes Anxiety Disorders in Adults?

The exact cause of anxiety disorders is not fully understood, and it is rarely a single factor. According to the NHS, things that can increase the likelihood of developing an anxiety disorder include:

  • A history of stressful or traumatic experiences, such as abuse, bereavement, or prolonged financial difficulty
  • Having close relatives with anxiety disorders or other mental health conditions
  • A long-term physical health condition, particularly one that is painful or unpredictable
  • Previous or current misuse of alcohol or drugs
  • Having another anxiety disorder or mental health condition

Anxiety disorders are more commonly diagnosed in women than in men, though this may partly reflect differences in help-seeking and how symptoms are recognised rather than a true difference in prevalence.

How Is an Anxiety Disorder Diagnosed?

A GP is the usual first step. They will ask about your symptoms, how long they have been present, and how much they are affecting your daily life. They may also rule out physical causes for symptoms such as palpitations or dizziness, which can be linked to anxiety but may also have other explanations.

A formal diagnosis is based on clinical assessment rather than a single test. If a GP suspects an anxiety disorder, they may refer you for a psychological assessment or suggest a talking therapies service. In England, adults aged 18 and over can also refer themselves directly to NHS talking therapies without going through a GP first.

What Treatment Is Available?

Treatment for anxiety disorders is effective, and many adults see significant improvement with the right support. The main options include:

  • 1
    Talking therapies: Cognitive Behavioural Therapy (CBT) is the most widely recommended approach. It focuses on the connection between thoughts, feelings, and behaviours, and building practical strategies to manage them. It is available through the NHS individually or in a group
  • 2
    Medication: a GP may prescribe a type of antidepressant known as an SSRI (Selective Serotonin Reuptake Inhibitor) to help manage anxiety, usually alongside talking therapies rather than as a standalone option
  • 3
    Self-help and lifestyle approaches: regular exercise, breathing techniques, reducing caffeine and alcohol, and relaxation strategies can all support day-to-day management of anxiety

Most people benefit from a combination of approaches, tailored to the type and severity of the disorder.

What Should You Do If You Think You Have an Anxiety Disorder?

If anxiety has been affecting your daily life for some time, it is worth speaking to someone rather than waiting for it to improve on its own. A GP is the usual starting point. If you would prefer not to wait for an NHS appointment or referral, KPI:Access can connect you with qualified specialists who provide anxiety assessments and support for adults.
