Panic attacks are extremely unpleasant and can be very frightening. As a result, people who experience repeated panic attacks often become very worried about having another attack and may make changes to their lifestyle so as to avoid having panic attacks. For example, avoiding exercise so as to keep their heart rate low, or avoiding certain places.
Research is inconsistent as to whether nutritional deficiencies (for example, zinc or magnesium deficiency) may be risk factors for panic disorder. While food additives like aspartame, alone or in combination with food dyes, are suspected to play a role in the development of panic attacks in some people, it has not been confirmed by research so far.
People with generalized anxiety disorder (GAD) display excessive anxiety or worry, most days for at least 6 months, about a number of things such as personal health, work, social interactions, and everyday routine life circumstances. The fear and anxiety can cause significant problems in areas of their life, such as social interactions, school, and work.
