Anxiety: Symptoms, Types and Treatment Options

Anxiety is your body’s natural response to stress or perceived threat — a “fight or flight” reaction that’s meant to be short-lived and protective. In an anxiety disorder, this response becomes disproportionate, persistent, or triggered without a clear cause, and starts interfering with everyday life: work, relationships, sleep, and physical health.

Anxiety affects both the mind and the body simultaneously. The most common symptoms include:

Psychological symptoms:

• Persistent worry or fear — a constant sense that something bad is about to happen
• Racing or intrusive thoughts — a mind that won’t switch off, even at night
• Difficulty concentrating — trouble focusing on tasks at work, school, or home
• Irritability — feeling on edge, snappy, or easily overwhelmed
• A sense of dread — even without an identifiable cause
• Avoidance behaviour — deliberately avoiding situations, places or people that trigger anxiety

Physical symptoms:

• Rapid or irregular heartbeat — palpitations that can feel alarming
• Shortness of breath — tightness in the chest or inability to take a full breath
• Sweating and trembling — particularly in social situations or during panic attacks
• Nausea and stomach problems — including diarrhoea, cramps, and appetite loss
• Dizziness and lightheadedness — a feeling of being detached from your surroundings
• Muscle tension and headaches — chronic tightness across the shoulders, neck, and jaw
• Insomnia — difficulty falling or staying asleep due to persistent worrying thoughts

If these symptoms have lasted more than two weeks and are affecting your daily life, it’s worth speaking to a GP.

Generalised Anxiety Disorder (GAD) — the most common form of anxiety in the UK, affecting around 5% of the population. Characterised by persistent, excessive worry about a wide range of everyday situations — work, health, finances, relationships — that’s difficult to control and significantly impacts daily functioning.

Panic Disorder — sudden, unexpected episodes of intense fear (panic attacks) that produce overwhelming physical symptoms: racing heart, difficulty breathing, dizziness, and a terrifying sense of losing control. Panic attacks typically peak within 10 minutes and can occur without any obvious trigger.

Social Anxiety Disorder — an intense fear of social situations, driven by overwhelming concern about being judged, embarrassed, or humiliated. Affects an estimated 1 in 10 people in the UK, and can make everyday activities — speaking at work, eating in public, making phone calls — feel impossible.

Health Anxiety — formerly known as hypochondria, an excessive and persistent preoccupation with having or developing a serious illness. More common in people who’ve experienced serious illness personally or in their family, and can lead to repeated, unnecessary medical appointments.

Post-Traumatic Stress Disorder (PTSD) — develops following exposure to a traumatic or life-threatening event, causing flashbacks, nightmares, severe anxiety, and emotional numbness that can persist for months or years without treatment.

Anxiety also commonly occurs alongside depression — the two conditions share overlapping symptoms and are often treated together.

Specific Phobias — an intense, irrational fear of a specific object or situation (heights, flying, needles, certain animals) that’s disproportionate to the actual danger and leads to active avoidance.

Agoraphobia — a fear of situations where escape might be difficult or help unavailable if things go wrong, such as crowded places, public transport, or being far from home. Often develops alongside panic disorder, and can become severe enough that someone avoids leaving the house altogether.

Stress and anxiety often feel similar, but they’re not the same thing. Understanding the difference can help you know when it’s time to seek support.

Some stress is a normal, even useful, part of life. Anxiety becomes a concern when it’s persistent, disproportionate, or starts limiting what you’re able to do. If your symptoms feel more connected to workload or exhaustion than to generalised worry, our Stress & Burnout guide may be a better starting point.

Quick answer: “Anxiety attack” isn’t an official medical term — it’s a phrase people use to describe a gradual build-up of intense worry. A panic attack, by contrast, is a recognised clinical term (defined in the DSM-5) for a sudden, short burst of intense fear that peaks within minutes, often without any clear trigger.

The two get confused constantly, but there are real differences worth knowing:

Both are genuinely frightening in the moment, and panic attacks in particular can feel like a heart attack or medical emergency — but they aren’t dangerous, even though they feel that way. If these episodes are happening regularly, it’s worth being properly assessed rather than trying to self-diagnose, since the right label helps guide the right treatment.

There’s rarely a single cause — usually a combination of factors:

• Family history — anxiety disorders can run in families, suggesting a genetic component
• Brain chemistry — imbalances in neurotransmitters like serotonin and GABA are linked to anxiety
• Life events — trauma, bereavement, relationship breakdown, or major life changes can trigger or worsen anxiety
• Chronic stress — prolonged work, financial, or caregiving stress can develop into a clinical anxiety disorder
• Physical health conditions — thyroid problems, heart conditions, and chronic illness are all linked to increased anxiety
• Substance use — alcohol, caffeine, and recreational drugs can trigger or worsen anxiety symptoms
• Personality traits — perfectionism and a tendency toward negative thinking patterns are associated with higher anxiety risk

A GP will typically start with a conversation about your symptoms, how long they’ve lasted, and how they’re affecting your daily life. There’s no single blood test or scan for anxiety — diagnosis is based on:

• Symptom history — using standardised questionnaires (such as GAD-7) to assess severity
• Ruling out physical causes — such as thyroid problems, which can mimic anxiety symptoms
• Identifying the specific type — GAD, panic disorder, social anxiety, health anxiety, or PTSD, as treatment can vary
• Assessing risk — checking for any thoughts of self-harm, and for co-existing depression, which commonly overlaps with anxiety

Anxiety is one of the most treatable mental health conditions — the vast majority of people see significant improvement with the right support.

The NHS generally follows a “stepped care” model for anxiety, starting with the least intensive effective option and stepping up only if needed:

1. Step 1 — Information, self-help resources, and watchful waiting for mild symptoms
2. Step 2 — Guided self-help, psychoeducational groups, or computerised CBT
3. Step 3 — Individual psychological therapy (such as CBT) or medication
4. Step 4 — Specialist mental health services, for complex or severe cases

This same logic applies broadly whether you’re treated on the NHS or privately — the goal is matching the treatment intensity to how severe and persistent your symptoms are, not jumping straight to the most intensive option.

Talking therapies:

• Cognitive Behavioural Therapy (CBT) — the most well-evidenced therapy for anxiety, helping identify and change unhelpful thought and behaviour patterns
• Counselling — supportive, exploratory talking therapy, useful alongside or instead of CBT depending on the person
• NHS Talking Therapies — a free, self-referral NHS service offering CBT and other evidence-based therapies

Medication:

• SSRIs (Selective Serotonin Reuptake Inhibitors) — the most effective first-line medication for most anxiety disorders, usually taken daily over the longer term
• Short-term anxiety relief medication — used cautiously and only where clinically appropriate, given the risk of dependence with longer-term use
• Beta-blockers — such as propranolol, sometimes used to manage the physical symptoms of anxiety, such as a racing heart, in specific situations like public speaking

Self-help and lifestyle:

• Regular exercise — shown to meaningfully reduce anxiety symptoms
• Reducing caffeine and alcohol — both can worsen anxiety symptoms
• Sleep hygiene — poor sleep and anxiety often feed into each other
• Structured relaxation techniques — breathing exercises, mindfulness, and progressive muscle relaxation

Both routes can get you effective treatment — the main differences are speed and choice:

If you’re currently facing a long NHS wait and your symptoms are affecting your daily life now, a private GP consultation can provide an assessment, treatment plan, and referral the same day — without replacing the option of NHS Talking Therapies self-referral running alongside it.

One of the most effective self-help approaches, drawn from CBT and recommended in NHS self-help guides, is gradually facing situations you’ve been avoiding rather than continuing to avoid them:

1. List the situations you tend to avoid because of anxiety (e.g. “giving a presentation”, “eating in a restaurant”)
2. Score each one from 0 (no anxiety) to 10 (extreme anxiety)
3. Start with the lowest-scoring situation and deliberately put yourself in it
4. Stay in the situation until your anxiety naturally starts to ease, rather than leaving as soon as it spikes
5. Work up the list gradually, moving to the next situation once the previous one feels more manageable

Avoidance tends to make anxiety worse over time, because it never gives you the chance to prove to yourself that you can cope. This approach works gradually and is often more effective when guided by a therapist, but the same underlying principle is one you can start applying yourself.

Myth: Anxiety is just overthinking — you can snap out of it. Fact: Anxiety is a recognised medical condition involving real changes in brain chemistry and the nervous system. It’s not a matter of willpower, and effective treatments exist.

Myth: Medication for anxiety will change your personality or make you dependent. Fact: SSRIs, the most commonly prescribed anxiety medication, are not addictive and don’t change who you are — they help restore balance to brain chemistry affected by anxiety.

Myth: If you’re anxious, you should avoid the things that trigger it. Fact: Long-term avoidance tends to reinforce anxiety. Structured, gradual exposure — often guided through CBT — is one of the most effective ways to reduce it.

Myth: Anxiety is always visible — if someone seems fine, they’re not anxious. Fact: Many people with anxiety are highly skilled at masking it outwardly while experiencing significant internal distress. You often can’t tell from the outside.

• Keep a symptom or worry diary to spot patterns and triggers ahead of GP appointments
• Build regular movement into your week — even short walks measurably reduce anxiety symptoms
• Limit caffeine and alcohol, both of which can heighten physical anxiety symptoms
• Practice grounding techniques (such as the 5-4-3-2-1 method) during moments of acute anxiety
• Prioritise a consistent sleep routine — anxiety and poor sleep often worsen each other
• Talk to someone you trust — isolation tends to intensify anxious thinking

Book an appointment if:

• Your anxiety has lasted longer than 2 weeks without improvement
• Worry and fear are affecting your ability to work, sleep, or socialise
• You are experiencing regular panic attacks
• You have started avoiding everyday situations because of anxiety
• You are using alcohol or other substances to cope with anxious feelings
• Your anxiety is accompanied by low mood
• Previous anxiety treatment has stopped working or feels insufficient

If you are having thoughts of harming yourself, please seek help immediately — speak to a GP urgently, call 111, or go to A&E if you feel unable to keep yourself safe.

If your anxiety is making it difficult to attend work, our GPs can also discuss a fit note as part of your consultation, where appropriate.
