What is Anxiety?
Problem anxiety may be caused by a mental condition, a physical condition, the effects of drugs, or from a combination of these. The doctor's initial task is to see if your anxiety is caused by a medical condition. Conditions as varied as anemia, asthma attack, infection, drug intoxication or withdrawal, or a number of heart conditions are just a few examples of medical problems that can be associated with anxiety.
Common types of anxiety are classified as a number of distinct mental conditions.
Panic disorder: In addition to attacks of anxiety, called panic attacks, common symptoms of panic disorders are stomach upset, palpitations (feeling your heart beat), dizziness, and shortness of breath. These same symptoms also can be caused by caffeine consumption, amphetamines ("speed" is the street slang for amphetamines when they are not prescribed by a doctor), an overactive thyroid, abnormal heart rhythms, and other heart abnormalities (such as mitral valve prolapse). The panic attack sufferer may experience their mind going blank or that they somehow do not feel real, in that they feel as if they are looking at themselves from outside of themselves. In order to qualify for the diagnosis of panic disorder, the individual would experience repeated panic attacks rather than just one episode.
Generalized anxiety disorder: Those who endure this condition experience numerous worries that are more often on the mind of the sufferer than not. Those worries interfere with the person's ability to sleep, frequently affect appetite, energy level, concentration, and other aspects of daily functioning.
Phobic disorders: People with phobias experience irrational fear that may rise to the level of panic attacks in response to a specific thing or situation. Examples of phobias include fears of spiders, insects in general, open spaces, closed-in spaces, air travel, heights, and social anxiety.
Obsessive compulsive disorder: Individuals with this condition either suffer from intrusive and distressing thoughts (obsessions) or engage in irresistible, often repetitive behaviors (compulsions). Examples of obsessions include worries about germs or having items in a particular order. Examples of compulsions include counting items or activities, avoiding walking on cracks, or avoiding touching doorknobs.
Separation anxiety disorder: Considered a disorder of children, separation anxiety disorder can be diagnosed when a child becomes extremely anxious in response to anticipating or being separated from one or more caregiving adults (usually a parent). The separation may come with the child's going to school each day or going to bed each evening, for example.
