(Specific Phobia; Simple Phobia)


A phobia is an intense fear to an object or situation. There are three main groups of phobias:
  • Agoraphobia —Fear of being trapped in places or situations that could be hard to escape.
  • Social phobia —Fear of social situations and being judged by others.
  • Specific phobia—Fear of a specific object or a situation.


The cause is not known. Genetics, the environment, and stressors may play a role.

Risk Factors

Phobias are more common in women. Other things that may raise the risk are:
  • Having a parent, sibling, or child with a phobia
  • Going through a stressful event, such as trauma or illness


Symptoms happen when a person is exposed to the object or situation that they fear. The fear may become more intense if the person cannot easily get away from it.
Mental health problems may be:
  • Intense feelings of panic and worry when exposed to the phobia
  • Fear of getting hurt, losing control, going crazy, or dying
  • Feelings of unreality or being detached from one's body
  • Knowing that the fear is not normal, but not being able to control the reaction
  • Wanting to flee from the fear or taking extreme steps to avoid it
  • A fear that gets in the way of daily activities
Physical problems may be:
  • Racing, pounding, or skipping heartbeat
  • Problems breathing
  • Chest pain
  • Sweating
  • Lightheadedness, feeling faint
  • Nausea
  • Tingling or numbness in parts of the body
  • Hot or cold flashes
