Anxiety is a very common condition and we have all experienced anxiety in some form of another when we have exams, interviews, etc. Anxiety disorders are found in 1 out of every 10 people.
Anxiety is described as experiencing fear when faced with difficult circumstances. The symptoms experienced can be varied and can range from sweating, palpitation (fast heart beat), fast breathing, shakes in hand, headaches, feeling the need to go to toilet more often, restless, feeling light headed (dizziness), nausea and feeling uncomfortable.
People can either experience anxiety in certain situations ( Social Anxiety) or it can be present at all times (Generalized Anxiety Disorder).
Panic is a form of extreme sudden anxiety which have all the symptoms of anxiety along with a feeling of loss of control and impending doom (death). Other very common symptoms in Panic are rigidity/spasm and bad posturing of hands (tetany) and feeling of numbness or pins and needles in fingers, toes and face.
Panic attacks usually come suddenly and the patient may not be in a difficult or threatening situation. Normally, patients complain of a feeling of having a heart attack and are usually rushed to Emergency rooms, where often they can get misdiagnosed as having a heart attack.
There are several theories about why people develop anxiety disorders. It is found more common in children of people suffering from anxiety and depressive disorders. Being exposed to frightening or disturbing circumstances can also cause anxiety disorders. Difficulties experienced during childhood and use of drugs and heavy alcohol can also initiate or make anxiety more troublesome.
