What is Anxiety Disorders? Causes & Symptoms of Anxiety

What is Anxiety Disorders

Having a feeling of anxiety is extremely normal. Everyone may feel anxious at some point in life, an exam, a medical test or an important interview. However, people with generalized anxiety disorder (GAD) are not just anxious for one specific event, they are hard to control their worries and feel anxious about a lot of situations and issues. The anxious feeling is always constant, lasts for a long time and affects their daily life.

What causes anxiety

Generalized anxiety disorder is a mental health, and the exact cause of it remains unclear so far. Genetics, brain chemistry and environmental stresses are suspected to be contributors of GAD.

Some researchers suggest that GAD runs in families. So genes may play a role for people developing GAD.

An imbalance of certain chemicals called neurotransmitters may be one of the causes of GAD. Once the level of these chemicals in your brain is out of balance, it can alter the way the brain react in certain situation, leading to anxiety.

Environmental factors like increased stress often appear to trigger the disorder. Many people develop GAD after a major stressful incident like divorce, job loss, a death in the family. But mental health professionals hold that stress is merely a trigger, not the cause.

Most researchers believe that GAD is caused by a combination of factors rather than single factor. Your body’s biological process, your environment, your life experience, and genetics may be combined to lead to the generalized anxiety disorder.
