Anxiety - Topic Overview

Feeling worried or nervous is a normal part of everyday life. Everyone frets or feels anxious from time to time. Mild to moderate anxiety can help you focus your attention, energy, and motivation. If anxiety is severe, you may have feelings of helplessness, confusion, and extreme worry that are out of proportion with the actual seriousness or likelihood of the feared event. Overwhelming anxiety that interferes with daily life is not normal. This type of anxiety may be a symptom of another problem, such as depression.

Anxiety can cause physical and emotional symptoms. A specific situation or fear can cause some or all of these symptoms for a short time. When the situation passes, the symptoms usually go away.

Physical symptoms of anxiety include:

  • Trembling, twitching, or shaking.
  • Feeling of fullness in the throat or chest.
  • Breathlessness or rapid heartbeat.
  • Lightheadedness or dizziness.
  • Sweating or cold, clammy hands.
  • Feeling jumpy.
  • Muscle tension, aches, or soreness (myalgias).
  • Extreme tiredness.
  • Sleep problems, such as the inability to fall asleep or stay asleep, early waking, or restlessness (not feeling rested when you wake up).

Anxiety affects the part of the brain that helps control how you communicate. This makes it harder to express yourself creatively or function effectively in relationships. Emotional symptoms of anxiety include:

  • Restlessness, irritability, or feeling on edge or keyed up.
  • Worrying too much.
  • Fearing that something bad is going to happen; feeling doomed.
  • Inability to concentrate; feeling like your mind goes blank.

Anxiety disorders occur when people have both physical and emotional symptoms. Anxiety disorders interfere with how a person gets along with others and affect daily activities. Women are twice as likely as men to have problems with anxiety disorders. Examples of anxiety disorders include panic attacks, phobias, obsessive-compulsive disorder, and post-traumatic stress disorder (PTSD).

Often the cause of anxiety disorders is not known. Many people with an anxiety disorder say they have felt nervous and anxious all their lives. This problem can occur at any age. Children who have at least one parent with the diagnosis of depression are more than twice as likely to have an anxiety disorder than other children.

Anxiety disorders often occur with other problems, such as:
