What is a phobia? What are the different kinds of phobias?

A phobia is defined as the unrelenting fear of a situation, activity, or thing that causes one to want to avoid it. The three kinds of phobias are social phobia (fear of public speaking, meeting new people or other social situations), agoraphobia (fear of being outside), and specific phobias (fear of particular items or situations). Phobias are largely underreported, probably because many phobia sufferers find ways to avoid the situations to which they are phobic. Therefore, statistics that estimate how many people suffer from phobias vary widely, but at minimum, phobias afflict more than 6 million people in the United States.

Other facts about phobias include that these illnesses have been thought to affect up to 28 out of every 100 people, and in all western countries, phobias strike 7%-13% of the population. Women tend to be twice as likely to suffer from a phobia compared to men. Some of the most common kinds of phobias include fears of public speaking or other social situations (social phobia or social anxiety disorder), open spaces (agoraphobia), closed-in spaces (claustrophobia), clowns (coulrophobia), flying (aerophobia), blood, animals (zoophobia), commitment (commitment phobia), driving, spiders (arachnophobia), needles (aichmophobia), snakes (ophidiophobia), math, heights (acrophobia or altophobia), germs (mysophobia), and having dental work done (dentophobia). Fears of midgets, haunted houses, helmets, pickles, and feet are just a few of the less common phobias and may be considered strange by some but can be just as debilitating as those phobias that are more common. Agoraphobia often coexists with panic disorder.

What are the effects of phobias?

If left untreated, a phobia may worsen to the point in which the person's life is seriously affected, both by the phobia itself and/or by attempts to avoid or conceal it. In fact, some people have had problems with friends and family, failed in school, and/or lost jobs while struggling to cope with a severe phobia. There may be periods of spontaneous improvement, but a phobia does not usually go away unless the person receives treatments designed specifically to help phobia sufferers. Alcoholics can be up to 10 times more likely to suffer from a phobia than those who are not alcoholics, and phobic individuals can be twice as likely to be addicted to alcohol than those who have never been phobic.

What are the causes and risk factors for phobias?

While there is no one specific known cause for phobias, it is thought that phobias run in families, are influenced by culture, and can be triggered by life events. Immediate family members of people with phobias are about three times more likely to also suffer from a phobia than those who do not have such a family history. Phobia sufferers have been found to be more likely to manage stress by avoiding the stressful situation and by having difficulty minimizing the intensity of the fearful situation.

What are the signs and symptoms of phobias?

Symptoms of phobias often involve having a panic attack -- in that they include feelings of panic, dread, or terror, despite recognition that those feelings are excessive in relationship to any real danger -- as well as physical symptoms like shaking, rapid heart beat, trouble breathing, and an overwhelming desire to escape the situation that is causing the phobic reaction. Also, extreme measures are sometimes taken to escape the situation.
