A phobia is a type of anxiety disorder defined by a persistent and excessive fear of an object or situation. Phobias typically, result in a rapid onset of fear and are present for more than six months. Those affected will go to great lengths to avoid the situation or object, to a degree greater than the actual danger posed. If the object or situation cannot be avoided, they experience significant distress. Other symptoms can include fainting, which may occur in blood or injury phobia, and panic attacks, which are often found in agoraphobia. Around 75% of those with phobias have multiple phobias.Phobias can be divided into specific phobias, social phobia, and agoraphobia. Specific phobias include those to certain animals, natural environment situations, blood or injury, and specific situations. The most common are fear of spiders, fear of snakes, and fear of heights. Specific phobias may be caused by a negative experience with the object or situation in early childhood. Social phobia is when a person fears a situation due to worries about others judging them.
