Feeling nervous before a big event is completely normal. But when anxious feelings become persistent, hard to control, or start affecting daily life, they may be pointing to something that deserves proper attention. Anxiety symptoms take many forms, and knowing what to look for is often the first step toward getting the right support.
Anxiety is one of the most common mental health conditions in the UK. According to the NHS, generalised anxiety disorder alone affects an estimated 5% of the population, with anxiety in its various forms affecting many more people than that.
What Is Anxiety?
Anxiety is the body’s natural response to stress or perceived threat. In short bursts, it can be useful, sharpening focus and helping you respond to a challenge. It becomes a problem when it is persistent, disproportionate, or when it begins to interfere with everyday life.
There are several recognised forms, including generalised anxiety disorder (GAD), social anxiety, panic disorder, and health anxiety. The symptoms across these conditions share common features, though they vary in how and where they show up.
What Are the Physical Symptoms of Anxiety?
Anxiety has a significant physical component that many people do not immediately connect to their mental state. According to the NHS, common physical symptoms include:
These symptoms are caused by the body’s stress response releasing adrenaline, which prepares it to act in the face of perceived danger. When anxiety is chronic, that response activates too frequently and without a genuine threat.
What Are the Psychological Symptoms?
The psychological side of anxiety is often what people notice first, though it can be harder to name. Mind, the UK mental health charity, describes psychological symptoms including a persistent sense of worry or dread, feeling on edge or unable to relax, difficulty concentrating, and a tendency to expect the worst.
Many people also experience a feeling of detachment from their surroundings, sometimes described as feeling unreal or disconnected. This is a recognised feature of anxiety disorders rather than a sign that something more serious is happening.
How Does Anxiety Affect Behaviour?
Anxiety does not only affect how you feel. It also changes what you do. Common behavioural patterns include:
| Behaviour | What It Can Look Like |
|---|---|
| Avoidance | Steering clear of situations, places, or people that feel triggering |
| Reassurance seeking | Repeatedly checking in with others to confirm that things are okay |
| Overpreparation | Spending disproportionate time preparing for events to feel in control |
| Withdrawal | Pulling back from social situations, work, or activities previously enjoyed |
| Irritability | Becoming easily frustrated, particularly when feeling overwhelmed |
These behaviours can feel like coping strategies in the short term but tend to reinforce anxiety over time rather than reducing it.
When Is Anxiety More Than Just Worry?
Everyone experiences worry and nervousness. The distinction between everyday anxiety and an anxiety disorder lies in how long symptoms last, how intense they are, and how much they affect daily life.
NICE guidelines on generalised anxiety disorder indicate that a diagnosis is considered when excessive worry is present on more days than not for at least six months, is difficult to control, and causes significant distress or impairment. If anxiety is affecting your work, relationships, sleep, or ability to carry out ordinary tasks, it is worth speaking to a professional rather than waiting to see if it passes.
What Should You Do If You Recognise These Symptoms?
- 1Speak to your GP: your General Practitioner is the first point of contact for most mental health concerns in the UK. They can discuss your symptoms, rule out physical causes, and refer you for appropriate support
- 2Keep a record: noting when symptoms occur, how long they last, and what seems to trigger them gives a clinician much more to work with
- 3Consider a professional assessment: a formal assessment can identify whether your experiences meet the criteria for an anxiety disorder and what treatment is most appropriate
- 4Do not wait: anxiety tends to become more entrenched over time without support, and early intervention generally produces better outcomes
