A number of medical conditions can cause anxiety symptoms. These include an overactive thyroid, hypoglycemia, mitral valve prolapse, anemia, asthma, COPD, inflammatory bowel disease, Parkinson's disease, and dementia among others. Your physician may perform certain tests to rule out these conditions. But it is important to remember that anxiety is more often due to poor coping skills or substance abuse than any medical condition.
Test anxiety is the uneasiness, apprehension, or nervousness felt by students who have a fear of failing an exam. Students who have test anxiety may experience any of the following: the association of grades with personal worth; fear of embarrassment by a teacher; fear of alienation from parents or friends; time pressures; or feeling a loss of control. Sweating, dizziness, headaches, racing heartbeats, nausea, fidgeting, uncontrollable crying or laughing and drumming on a desk are all common. Because test anxiety hinges on fear of negative evaluation, debate exists as to whether test anxiety is itself a unique anxiety disorder or whether it is a specific type of social phobia. The DSM-IV classifies test anxiety as a type of social phobia.
In fact, some studies have suggested that people with chronic anxiety disorders have an increased prevalence of CAD—that is, chronic anxiety may be a risk factor for CAD. So doctors should not be too quick to simply write the chest pain off as being “simply” due to anxiety. They should at least entertain the possibility that both disorders may be present and should do an appropriate evaluation.
People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).
