Once in our life we felt anxious about something, like a person or a situation. Anxiety is a feeling of apprehension, worry, nervousness, or fear. Headaches, trembling, muscle tension, abdominal pain, sweating, and diarrhea are only some of its symptoms. There are various reasons why we feel anxious. It can be due to a particular circumstance, the surroundings, past experiences, medical reasons, or a combination of these. Others link anxiety to brain imbalance due to medications. To learn more about its causes, below are some factors that contribute in the development of anxiety disorder.
- Research shows a link between anxiety disorder and genetics. Studies show that if one of the identical twins demonstrates this disorder, the other twin could possibly have the sickness as well. This illustrates that heredity could probably play a role in getting anxiety disorder.

- The personality of a person could also contribute in having the illness. If one has low self-esteem and cannot easily deal with the changing environment or circumstances, he or she is more susceptible to have anxiety disorder. On the other hand, developing the disorder at an early age can then be a factor in developing low self-confidence.
- People who have phobia can feel anxious when faced with a situation or a thing that they fear. They start to panic and feel nervous. Having phobic disorder is closely related to anxiety disorder.
- The chemistry of the brain can possibly be linked to the sickness, based on some studies. This theory was arrived at due to the fact that medications are given to relieve those with anxiety disorder. Such medications change the chemical levels in the brain to make them calm.
- Bad experiences in life are also factors that could lead to anxiety disorder. Those who experienced poverty, violence, abuse, and other traumatic events are more prone to have the sickness.
- Stress from different aspects such as school, work, medical condition, emotional problems, etc., greatly contribute in the development of anxiety disorder. Minimal stress can be healthy as it pushes an individual to work harder. On the other hand, too much stress can be serious and can lead to anxiety disorder.
- It is a known fact that illegal drugs cause various bad side effects. One of which is anxiety disorder.
- Certain medications also cause anxiety. And usually, as a side effect of taking such medications, companies make sure to indicate this in their packaging for the consumers to be cautious.
