Anxiety is a multifaceted response to either real or perceived threats, encompassing a range of cognitive, physical, and behavioral changes.

Sometimes, the intensity and duration of anxiety can be disproportionate to the original stressor or trigger. This can lead to physical symptoms such as nausea and increased blood pressure, which can extend beyond anxiety and develop into an anxiety disorder.

When anxiety escalates to a disorder, it can negatively affect daily life and interfere with regular functions.

While many people will occasionally experience these symptoms in daily life, people with general anxiety disorder (GAD) will experience them at persistent or extreme levels.


The Diagnostic and Statistical Manual of Mental Health Disorders: 5th Edition, text revision (DSM-5-TR) classifies anxiety disorders into several main types.

In previous editions of the DSM-5-TR, anxiety disorders included obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD), as well as acute stress disorder. However, the manual no longer groups trusted Sources of these mental health difficulties under anxiety.

Panic disorder

Brief or sudden attacks of intense terror and apprehension characterize the panic disorder. These attacks can lead to shaking, confusion, dizziness, nausea, and breathing difficulties. Panic attacks tend to occur and escalate rapidly.

Panic disorders usually occur after frightening experiences or prolonged stress but may also occur without a trigger.

Specific phobia

This is a fear and avoidance of a particular object or situation. Phobias are not like other anxiety disorders, as they relate to a specific causeTrusted Source.

A person with a phobia might acknowledge fear as illogical or extreme but remain unable to control feelings of anxiety around the trigger. Triggers for a phobia range from situations and animals to everyday objects.


This is a fear and avoidance of places, events, or situations from which it may be difficult to escape or where help would not be available in emergencies.

People often misunderstand this condition as a phobia of open spaces and the outdoors. A person with agoraphobia may fear leaving home or using elevators and public transport.

Selective mutism

Some children experience this form of anxiety, in which they cannot speak in certain places or contexts, even though they may have excellent verbal communication skills around familiar people.

The causes of anxiety disorders are complicated. Many might occur at once, some may lead to others, and some might not lead to an anxiety disorder unless another is present.

Possible causes include:

  • environmental stressors, such as relationship problems or family issues
  • genetics
  • medical factors, such as disease symptoms or the effects of a medication
  • substance withdrawal

Treatment is often consistsTrusted Source of psychotherapy, behavioral therapy, and medication.

Sometimes, alcohol dependence, depression, or other underlying conditions require treatment before treating an anxiety disorder can take place.


Sometimes, a person can treat an anxiety disorder at home without clinical supervision. However, this may not be effective for severe or long-term anxiety disorders.

There are several exercises and actions to help a person cope with milder, more focused, or shorter-term anxiety disorders, including:

  • stress management
  • relaxation techniques
  • maintaining support networks
  • physical exercise


A standard way of treating anxiety is psychological counseling. This can include cognitive behavioral therapy (CBT), psychotherapy, or a combination of therapies.

CBT is a type of psychotherapy that aims to recognize and change harmful thought patterns that form the foundation of anxious and troublesome feelings.


A person can support anxiety management with several typesTrusted Sources of medication.

Medicines that might control some physical and mental symptoms include antidepressants, benzodiazepines, and tricyclic antidepressants.

  • Benzodiazepines: A doctor may prescribe these for certain people with anxiety, but they can cause addiction. Diazepam, or Valium, is a common benzodiazepine.
  • Antidepressants: These commonly help with anxiety, even though they also target depression. Serotonin reuptake inhibitors (SSRIs), fluoxetine, and citalopram are examples.
  • Tricyclic antidepressants: These are an older class of drugs that benefit most anxiety disorders other than obsessive-compulsive disorder (OCD). Imipramine and clomipramine are two examples of tricyclics.

Additional drugs a person might use to treat anxiety include:

  • monoamine oxidase inhibitors (MAOIs)
  • beta-blockers
  • buspirone

Seek medical advice if the adverse effects of any prescribed medications become severe.


There are ways to reduce the risk of anxiety disorders. Remember that anxious feelings are a natural factor of daily life, and experiencing them does not always indicate the presence of a mental health disorder.

People may benefit from the following:

  • reducing caffeine intake
  • checking with a health professional before using over-the-counter or herbal remedies
  • maintaining a balanced, nutritious diet
  • keeping a regular sleep pattern
  • regularly exercising
  • avoiding alcohol, cannabis, and other recreational drugs


Anxiety is not a medical condition but a natural emotion that is vital for survival when an individual faces danger.

An anxiety disorder develops when this reaction becomes exaggerated or out-of-proportion to the trigger that causes it. There are several types of anxiety disorders, including panic disorder, phobias, and social anxiety.

Treatment involves a combination of therapy, medication, and counseling alongside self-help measures.

An active lifestyle with a balanced diet can help keep anxious emotions within healthy limits.
