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.

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.


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.
