What is Anxiety

Anxiety is the response of the body during fear. Anxiety is a disorder results from the fear response becoming out of proportion to the actual risk. Anxiety disorders involve excessive levels of negative emotions, such as fear, worry, nervousness, and tension, and the anxious feelings occur involuntarily despite your best attempts to avoid them or stave them off.

The body responds to anxiety stimulus both physically and mentally. Anxiety can lead to over-stimulation of the sympathetic nervous system. It manifests by the physical symptoms such as a racing heartbeat, sweating and trembling, and psychological symptoms such as restlessness, insomnia and difficulty in concentrating.Anxiety is often seen as a triggering of the fight-or-flight reaction, causing excess adrenaline to be produced by the adrenal glands, which in turn produce other hormones (catecholamines) that affect various parts of the body, such as heartbeat and respiration.

Causes of Anxiety Disorder:-
The cause of anxiety disorder has been studied for decades. There are various reasons for feeling the way that you do. Modern studies indicate that as a result of past, present or perceived circumstances that occurred to an individual, a chemical imbalance may have occurred in the brain. The emotions we feel are based on the release and reuptake of neurotransmitters in the brain. This is how cells within the brain communicate. Feelings off anxiety are triggered by an imbalance of specific 'neurochemicals' in the brain.

What is the cause of the chemical imbalance?
Some theories suggest that chemical imbalances are a normal part of life. Everyone feels stressed or anxious at times, even depressed. This is a normal response by our body to events occurring around us. It is important to note that the physical or mental feelings we experience and exhibit are being caused by the release of chemicals and hormones in our brains. Most modern methods for treating chemical imbalances come in the form of prescription medications. Drugs like Paxil, Prozac and Effexor are believed to have a direct effect on key neurotransmitters.
