ANXIETY

Experiencing occasional anxiety is a normal part of life. However, people with anxiety disorders frequently have intense, excessive and persistent worry and fear about everyday situations. Often, anxiety disorders involve repeated episodes of sudden feelings of intense anxiety and fear or terror that reach a peak within minutes (panic attacks).

These feelings of anxiety and panic interfere with daily activities, are difficult to control, are out of proportion to the actual danger and can last a long time. You may avoid places or situations to prevent these feelings. Symptoms may start during childhood or the teen years and continue into adulthood.

Examples of anxiety disorders include generalized anxiety disorder, social anxiety disorder (social phobia), specific phobias and separation anxiety disorder. You can have more than one anxiety disorder. Sometimes anxiety results from a medical condition that needs treatment.

Whatever form of anxiety you have, treatment can help.

Symptoms

Common anxiety signs and symptoms include:

Feeling nervous, restless or tense

Having a sense of impending danger, panic or doom

Having an increased heart rate

Breathing rapidly (hyperventilation)

Sweating

Trembling

Feeling weak or tired

Trouble concentrating or thinking about anything other than the present worry

Having trouble sleeping

Experiencing gastrointestinal (GI) problems

Having difficulty controlling worry

Having the urge to avoid things that trigger anxiety

Several types of anxiety disorders exist:

Agoraphobia (ag-uh-ruh-FOE-be-uh) is a type of anxiety disorder in which you fear and often avoid places or situations that might cause you to panic and make you feel trapped, helpless or embarrassed.

Anxiety disorder due to a medical condition includes symptoms of intense anxiety or panic that are directly caused by a physical health problem.

Generalized anxiety disorder includes persistent and excessive anxiety and worry about activities or events — even ordinary, routine issues. The worry is out of proportion to the actual circumstance, is difficult to control and affects how you feel physically. It often occurs along with other anxiety disorders or depression.

Panic disorder involves repeated episodes of sudden feelings of intense anxiety and fear or terror that reach a peak within minutes (panic attacks). You may have feelings of impending doom, shortness of breath, chest pain, or a rapid, fluttering or pounding heart (heart palpitations). These panic attacks may lead to worrying about them happening again or avoiding situations in which they've occurred.

Selective mutism is a consistent failure of children to speak in certain situations, such as school, even when they can speak in other situations, such as at home with close family members. This can interfere with school, work and social functioning.

Separation anxiety disorder is a childhood disorder characterized by anxiety that's excessive for the child's developmental level and related to separation from parents or others who have parental roles.

Social anxiety disorder (social phobia) involves high levels of anxiety, fear and avoidance of social situations due to feelings of embarrassment, self-consciousness and concern about being judged or viewed negatively by others.

Specific phobias are characterized by major anxiety when you're exposed to a specific object or situation and a desire to avoid it. Phobias provoke panic attacks in some people.

Substance-induced anxiety disorder is characterized by symptoms of intense anxiety or panic that are a direct result of misusing drugs, taking medications, being exposed to a toxic substance or withdrawal from drugs.

Other specified anxiety disorder and unspecified anxiety disorder are terms for anxiety or phobias that don't meet the exact criteria for any other anxiety disorders but are significant enough to be distressing and disruptive.

PANIC DISORDER

A panic attack is a sudden episode of intense fear that triggers severe physical reactions when there is no real danger or apparent cause. Panic attacks can be very frightening. When panic attacks occur, you might think you're losing control, having a heart attack or even dying.

Many people have just one or two panic attacks in their lifetimes, and the problem goes away, perhaps when a stressful situation ends. But if you've had recurrent, unexpected panic attacks and spent long periods in constant fear of another attack, you may have a condition called panic disorder.

Symptoms

Panic attacks typically begin suddenly, without warning. They can strike at any time — when you're driving a car, at the mall, sound asleep or in the middle of a business meeting. You may have occasional panic attacks, or they may occur frequently.

Panic attacks have many variations, but symptoms usually peak within minutes. You may feel fatigued and worn out after a panic attack subsides.

Panic attacks typically include some of these signs or symptoms:

Sense of impending doom or danger

Fear of loss of control or death

Rapid, pounding heart rate

Sweating

Trembling or shaking

Shortness of breath or tightness in your throat

Chills

Hot flashes

Nausea

Abdominal cramping

Chest pain

Headache

Dizziness, lightheadedness or faintness

Numbness or tingling sensation

Feeling of unreality or detachment

One of the worst things about panic attacks is the intense fear that you'll have another one. You may fear having panic attacks so much that you avoid certain situations where they may occur.

Although panic attacks themselves aren't life-threatening, they can be frightening and significantly affect your quality of life. But treatment can be very effective.
