Anxiety is felt by everyone now and then, but uncontrolled anxiety or panic attacks can be a debilitating and terrifying experience. In some cases, the episodes become chronic and ongoing, interfering with a persons ability to live a productive life. Anxiety can strike at any age and appears to affect twice as many women as men.

We all experience the feelings of nervousness, dread or apprehension - and most of the time these feelings are a perfectly normal response to stress. However, anxiety may manifest itself in a variety of physical symptoms, including: chest pains, chills, clamminess, dizziness, difficulty breathing, excessive sweating, fainting, hot flashes, insomnia, intestinal distress (diarrhea, nausea, stomach cramps) and a pounding heartbeat.

In addition to the physical symptoms, one experiencing a panic attack typically feels an overwhelming sense of terror. A panic attack is an instance in which the body's natural "fight or flight" reaction occurs at the wrong time. The physical and emotional symptoms are so terrifying that those who experience panic attacks often are convinced they are having a heart attack.

Panic attacks are unpredictable. Fears caused by the anticipation of a panic attack only adds to the level of anxiety which interferes with normal everyday living and lives being abnormally limited.

Because anxiety disorders tend to run in families, there may well be a genetic component. There is considerable debate about the causes of panic attacks, many experts believe that a neuro-chemical imbalance can trigger both anxiety disorders and depression. (Those prone to depression also tend to experience panic attacks.)

Although prescription medicine and psychological treatments can be helpful in managing anxiety, natural remedies also can be helpful.
