About Anxiety

Anxiety is a feeling of fear, dread, and uneasiness. It might cause you to sweat, feel restless and tense, and have a rapid heartbeat. It can be a normal reaction to stress. For example, you might feel anxious when faced with a difficult problem at work, before taking a test, or before making an important decision. It can help you to cope. The anxiety may give you a boost of energy or help you focus. But for people with anxiety disorders, the fear is not temporary and can be overwhelming.

Anxiety disorders are conditions in which you have anxiety that does not go away and can get worse over time. The symptoms can interfere with daily activities such as job performance, schoolwork, and relationships.

There are several types of anxiety disorders, including:

  • Generalized anxiety disorder (GAD). People with GAD worry about ordinary issues such as health, money, work, and family. But their worries are excessive, and they have them almost every day for at least 6 months.
  • Panic disorder. People with panic disorder have panic attacks. These are sudden, repeated periods of intense fear when there is no danger. The attacks come on quickly and can last several minutes or more.
  • Phobias. People with phobias have an intense fear of something that poses little or no actual danger. Their fear may be about spiders, flying, going to crowded places, or being in social situations (known as social anxiety).

The cause of anxiety is unknown. Factors such as genetics, brain biology and chemistry, stress, and your environment may play a role.

The risk factors for the different types of anxiety disorders can vary. For example, GAD and phobias are more common in women, but social anxiety affects men and women equally. There are some general risk factors for all types of anxiety disorders, including:

  • Certain personality traits, such as being shy or withdrawn when you are in new situations or meeting new people
  • Traumatic events in early childhood or adulthood
  • Family history of anxiety or other mental disorders
  • Some physical health conditions, such as thyroid problems or arrhythmia

The different types of anxiety disorders can have different symptoms. But they all have a combination of:

  • Anxious thoughts or beliefs that are hard to control. They make you feel restless and tense and interfere with your daily life. They do not go away and can get worse over time.
  • Physical symptoms, such as a pounding or rapid heartbeat, unexplained aches and pains, dizziness, and shortness of breath
  • Changes in behavior, such as avoiding everyday activities you used to do

Using caffeine, other substances, and certain medicines can make your symptoms worse.

To diagnose anxiety disorders, your health care provider will ask about your symptoms and medical history. You may also have a physical exam and lab tests to make sure that a different health problem is not the cause of your symptoms.

If you don't have another health problem, you will get a psychological evaluation. Your provider may do it, or you may be referred to a mental health professional to get one.

The main treatments for anxiety disorders are psychotherapy (talk therapy), medicines, or both:

  • Psychotherapy can help you recognize and change troubling emotions, thoughts, and behaviors. To be effective, it should focus on your specific anxieties and needs. There are many types; some of the types used for anxiety disorders include: Cognitive behavioral therapy (CBT), which teaches you different ways of thinking and behaving. It can help you change how you react to the things that cause you to feel fear and anxiety. It may include exposure therapy. This therapy focuses on having you confront your fears so that you will be able to do the things that you had been avoiding.
  • Acceptance and commitment therapy may help with some anxiety disorders. It uses strategies such as mindfulness and goal setting to reduce discomfort and anxiety.

Support groups and stress management techniques may also be helpful.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Anxiety

10,365 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
