What Is Anxiety Disorder?

Anxiety disorders refer to a variety of mental disorders, in which patients undergoing these disorders experience a variety of exaggerated and, sometimes, paranoid symptoms. Common symptoms include fear, anxiety, anger, feeling of doom or something bad about to happen, trembling, rapid heart rate, sweating and loss of concentration among others. While the disorders do not yet have a clearly defined cause, some physical illnesses, psychological trauma and genetics may contribute to the occurrence of these disorders. Treatment for anxiety disorders may be obtained through drugs and or psychological counseling/ therapy.

Types and Symptoms of anxiety disorders

Anxiety disorders range widely. Common ones include particular phobias, social phobia, agoraphobia, selective mutism, separation anxiety disorder, substance-induced anxiety disorder and panic disorder among others. Symptoms of any one anxiety disorder can exhibit in the form of psychological, physiological or emotional symptoms. Trembling/ shivering, headaches, nail biting, nausea, stomach aches, constipation, increased bowel movement or urination frequency comprise some of the physiological symptoms that a person, who experiences one anxiety disorder or another exhibits, and which should make a person seek medical help. Delusions, extreme paranoia, worry, anger, depression, fear, and sometimes suicidal thoughts comprise some of the psychological and emotional symptoms that patients experience.

Common causes of anxiety disorders

Causes of anxiety disorders can be physical health-related, psychological and life experience-related, genetical or even neurological. Physical conditions and diseases such as heart problems, menopause, gastroesophageal reflux disease, hyperthyroidism and hypothyroidism have been attributed to being some of the causes of anxiety disorders. Life experiences and psychological trauma such as a strong rejection or discrimination, accidents tied to a specific event and life uncertainties, comprise some of the psychological and life experiences that trigger one type of anxiety disorder or another; leading people to overly react to situations that do not carry the weight or danger these people perceive. Drugs have been known to mess up with the neurological system of the brain and the CNS (central nervous system); thereby leading to paranoia, involuntary trembling, accelerated heart beat and an inappropriate reaction to external stimuli.

Risk factors

While anybody may suffer anxiety disorder of one type or another, people who already have other mental illnesses, are constantly using or abusing drugs, or have relatives who suffer the same are highly prone to suffering anxiety disorders. Additionally, certain personality types, such as perfectionists and introverts, among others, may be highly predisposed to some anxiety disorders than their counterparts. People who were subjected to emotional or physical suffering at one point or another in their lives may also suffer some anxiety disorders.


Some people exhibit extreme fear, anxiety, accelerated heartbeat and inversely proportional reactions to external stimuli, which do not elicit the same physiological or psychological/ emotional reactions in other people. These anxiety disorders range from situational, drug and chemical-induced, psychological trauma and physical trauma among others. People can seek treatment for anxiety disorders in the form of psychological therapy and use of drugs that help people calm down or process reality in real time.
