While there are numerous panic attack causes, no single cause has been singled out as the most prominent one. Nonetheless, several theories have claimed that panic attacks arise from a combination of biological, environmental, genetic, social, as well as real-life experiences. The complex interaction between these factors often leads to psychological imbalances in human beings, thereby causing chronic anxiety attacks. Let us now take a closer look at some of these:

1. Biological Reasons

The human brain contains millions of chemical messengers which constantly interact with each other. GABA, serotonin and norepinephrine are a few neurotransmitters which play a major role in maintaining the panic disorder in the human body. If any one of these neurotransmitters is imbalanced, it triggers a violent reaction in the human brain thereby causing panic attacks.

2. The Fight Or Flight Theory

The second cause of panic attacks is the fight and the flight syndrome, which in turn is triggered because it is inbuilt in the body's alarm system. This is a natural fight or flight syndrome which is also present in animals as well as birds. In simple words, when a human body perceives a possible threat, it changes physically as well as psychologically and either gears up for a fight or informs the person to 'take a flight'.

3. The Theory Of False Alarm

After several years of studies, researchers have come to the conclusion that carbon dioxide has a major role to play in triggering panic related attacks. According to this theory, when the existing levels of CO2 and oxygen are changed; a signal of 'possible suffocation' is dispatched to the brain. This results in panic. People who are extremely sensitive to the changes in the level of oxygen and CO2 have been known to suffer from acute panic attacks. Owing to a sudden rise in anxiety, the breathing level of a human being is greatly disrupted. Disrupted breathing upsets the exchange between CO2 and oxygen and leads to an imbalance between the two.
