You may feel unnaturally afraid all of the sudden, and in mortal danger. You are not alone. Between 6.5 – 10% of Americans have been diagnosed with Panic Disorder, which means the individual has suffered more than one panic attack within a period of time. There are several successful treatments available from conventional physicians and therapists. Any number or combination of a number of things can help anxiety attacks from taking over your life. An anxiety attack is a sudden rush of physical and mental discomfort or trauma caused by unknown or known sources. Panic attacks could be generated through bad traffic, a stressful morning, or nothing at all. There are a variety of conditions that may cause anxiety attacks or an anxiety attack disorder. They include but are not limited to: low blood sugar levels, certain heart conditions, excessive intake of caffeine, drug use, tumors (some tumors cause excess adrenaline which can lead to anxiety attacks), or an overactive thyroid gland. Because of this elevated anxiety, people with panic attack and depression will often experience panic attacks on a normal basis. When someone has more than one panic attack, they can develop a phobia towards the situation, or a fear to return to a specific place. Add in an already depressed view of the world, a worry that others find no worth in you, and you have a recipe for one miserable person. Mainly because the attack is even less rational then a standard panic attack. Why they experience a fear of traveling beyond a certain distance, or going to a certain place is unknown. But anyone of the numerous anxiety / panic disorders can take root and cause agoraphobia. Social anxiety can lead to a fear of certain public places, especially grocery stores and other places that have a large gathering of people. Anxiety Attack Heart Problems Anxiety attack heart problems are any problems related to the cardiovascular system of your body that are caused by anxiety or panic attacks. Due to the very nature of a panic attack, it is not surprising that anxiety attack heart problems are among the leading causes of heart attacks or other cardiovascular issues among North Americans today.
