Anxiety is an emotion that may feature excessive worry, sleep disturbances, shakiness, ritualistic behavior, fear of being alone or in public places, impatience, easy distraction, and great apprehension concerning the welfare of loved ones. Associated physical symptoms include racing pulse, heart palpitations, shortness or rapidity of breath, sweating, dry mouth, numbness, and tingling of the hands and feet or cold/clammy hands, lightheadedness or dizziness, fatigue, trembling, indigestion, and diarrhea.
Anxiety disorders occur in people of all ages, but appear to be more common among women. The occurrence of an anxiety or panic attack is often unpredictable, but it may be associated with certain situations such as driving a car. The exact cause is complex, involving constitutional factors, emotional stress, biochemical imbalances, and environmental triggers. In women, hormone imbalances can cause anxiety. Therefore, hormone assessment is essential. Amino and fatty acid imbalances can also play an important role in triggering anxiety attacks.
