Key facts
- Anxiety disorders are among the most common mental health conditions worldwide.
- Occasional anxiety is normal; an anxiety disorder involves intense, persistent worry that interferes with daily life.
- The core treatments are psychotherapy, medication, or both, and they work for most people.
- Anxiety often appears alongside depression, and both can be treated together.
What is anxiety?
Anxiety is a feeling of fear, dread, or unease in response to a perceived threat. In small doses it is useful: it sharpens focus, helps you prepare, and keeps you safe. Everyone feels anxious before an exam, a big decision, or a difficult conversation, and that is healthy.
An anxiety disorder is different. The worry is more intense than the situation calls for, it does not go away, and it gets in the way of work, relationships, and everyday activities. Anxiety disorders are real medical conditions with biological, psychological, and social roots, not a sign of weakness or something you can simply talk yourself out of. The good news is that they respond well to treatment.
Symptoms
Anxiety affects the mind and the body. Common signs include:
- Excessive, hard-to-control worry or fear
- A sense of restlessness or feeling on edge
- Difficulty concentrating or the mind going blank
- Irritability
- Muscle tension
- Trouble falling or staying asleep
- Racing heart, shortness of breath, or chest tightness
- Sweating, trembling, or shaking
- Stomach upset, nausea, or dizziness
- Avoiding situations that trigger the anxiety
When these symptoms are frequent, persist for months, and interfere with daily life, they may point to an anxiety disorder.
Types of anxiety disorders
- Generalized anxiety disorder: chronic, excessive worry about many everyday things, often without a clear cause.
- Panic disorder: recurrent, unexpected panic attacks and fear of having more. See our guide to panic disorder.
- Social anxiety disorder: intense fear of being judged, embarrassed, or scrutinized in social situations.
- Phobias: strong, irrational fear of a specific object or situation. See phobias.
- Separation anxiety disorder: excessive fear of being apart from people you are attached to.
Related conditions such as OCD and PTSD were once grouped with anxiety disorders and share some features, though they are now classified separately.
Causes and risk factors
There is no single cause. Anxiety disorders usually develop from a mix of factors:
- Biology: brain chemistry and genetics. Anxiety can run in families.
- Temperament: being naturally shy or prone to negative emotions in childhood.
- Life events: trauma, stress, abuse, or significant change.
- Health: certain physical conditions, chronic illness, and some medications.
- Substance use: caffeine, alcohol, and drug use can trigger or worsen anxiety.
How anxiety is treated
Anxiety disorders are highly treatable. Most people improve significantly with treatment, and a combination often works best.
Psychotherapy
Talk therapy, especially cognitive behavioral therapy (CBT), is a first-line treatment. CBT helps you recognize and reframe the thoughts that fuel anxiety, and exposure therapy gradually and safely reduces fear of the situations you avoid. The skills learned tend to last.
Medication
Several medications can ease anxiety, including antidepressants such as SSRIs and SNRIs, which are often used long term. Other medicines may be used for short-term relief. All should be managed by a prescriber. Learn more about antidepressants.
Lifestyle and self-care
Regular physical activity, good sleep, slow breathing and relaxation techniques, limiting caffeine and alcohol, and staying socially connected all help manage anxiety. These complement, but do not replace, professional treatment for moderate to severe anxiety.
When to seek help
Reach out to a doctor or mental health professional if worry and fear feel out of control, last for months, or interfere with work, relationships, or daily life. Also seek help if anxiety leads you to avoid important activities or if you rely on alcohol or other substances to cope. Treatment is effective, and getting help early makes recovery easier.
Frequently asked questions
What is the difference between normal anxiety and an anxiety disorder?
Normal anxiety is temporary and tied to a specific stressor, and it fades once the situation passes. An anxiety disorder involves worry that is intense, persistent, out of proportion to the situation, and disruptive to daily life.
Can anxiety be cured?
Many people experience lasting relief with treatment. While anxiety may not vanish entirely, therapy and medication can reduce symptoms to a manageable level and give you tools to handle it long term.
Is anxiety a physical or mental condition?
Both. Anxiety affects the mind through worry and fear, and the body through symptoms like a racing heart, muscle tension, and stomach upset. Effective treatment addresses both sides.
