There are a lot of theories on why anxiety disorders develop. Like other forms of mental illness, it comes from a combination of many factors like brain changes, genetics, and environmental factors.

Anxiety disorders run in families, and it’s associated with the faulty circuits in the brain that controls the emotions and fear.

5Risk factors

Just one factor doesn’t cause an anxiety disorder but a combination of things. Here are the risk factors for anxiety disorder.

Family History

A family history of mental health conditions may increase the likelihood of a person to develop anxiety disorders. However, having a family member who experiences anxiety disorder or other mental health problems doesn’t mean you’ll have one too automatically.


Some research suggests that people with certain personality traits. Individuals who are perfectionists, timid, inhibited, controlling, lack self-esteem and who are easily flustered are more likely to develop anxiety.

Stressful Events

During an ongoing stressful event, anxiety conditions may develop or progress. The most common triggers are changes in living arrangements, being laid off from work, changes and stress in work, family conflicts, pregnancy and giving birth, relationship problems, emotional shock, traumatic events, death or loss of a loved one, and verbal, sexual, physical or emotional trauma or abuse.

Physical Illness

Having a physical or health problem may increase the risk of developing anxiety disorders. Chronic diseases may contribute to anxiety disorders such as diabetes, asthma, heart disease and hypertension.


An anxiety disorder is a medical condition that can interfere with one’s life. People who have this condition find it hard to handle school or job responsibilities, perform daily tasks, concentrate and maintain relationships. At times, they may even have a difficult time getting out of bed.

When anxiety is left untreated, it can increase the risk of severe and even life-threatening complications.


Depression often occurs with general anxiety disorder. It’s a prevalent condition in people with anxiety that sometimes, it’s hard to distinguish the two.

Bipolar Disorder

Some symptoms of people with anxiety are common in those who have bipolar disorder. In fact, the presence of anxiety may worsen the condition.

Suicidal Thoughts

Panic disorder is commonly associated with a risk of suicidal thoughts. Studies have shown that 18 percent of people with panic disorder attempt suicide. Other types of anxiety disorders increase the risk of suicide. When any of these disorders are accompanied by depression, the risk is higher.

Physical Effects

Anxiety disorders may affect one’s physical health. Research suggests that people who have an anxiety disorder and a physical illness have a worse quality of life. Moreover, they have an increased risk of disability.

Another physical effect of anxiety disorders is heart disease. People with anxiety disorders commonly have cardiovascular diseases such as unhealthy cholesterol levels, thicker blood vessels, and hypertension.


Anxiety is difficult to diagnose. A complete physical examination is necessary. This helps the doctor rule out other illnesses that may be causing the symptoms. Moreover, a complete personal history is needed for an accurate diagnosis.

Laboratory examinations are also required if a medical condition is suspected and the doctor will ask detailed questions about the medical history and symptoms.

Here are other diagnostic tests for anxiety disorders:

Zung Self-Rating Anxiety Scale

The Zung Self-Rating Anxiety Scale is a 20-item questionnaire wherein you’ll rate your condition on subjects like shaking, anxiety, racing heartbeat, being nervous, frequent urination, fainting, and nightmares.

Hamilton Anxiety Scale (HAM-A)

The Hamilton Anxiety Scale (HAM-A) is a test to determine and rate moods, tension, and fears. It’s one of the first rating scales for anxiety.

Anxiety disorders and depression are treatable. There are many treatment options you can choose from.


When it comes to the treatment of anxiety disorders, the most common and effective method is through therapy. Therapy, unlike medications, helps treat more than just the symptoms but also the underlying causes of the worries and fear. You will learn how to relax and develop coping mechanisms.

Cognitive Behavioral Therapy

Cognitive behavioral therapy is now a widely-used treatment option for anxiety. Cognitive therapy examines how negative thoughts contribute to anxiety, and behavioral therapy sees how a person behaves in situations that trigger anxiety.


Medications used in the treatment of anxiety are safe and effective. It’s used in conjunction with therapy. The most commonly used medications are the following:

  • Selective Serotonin Reuptake Inhibitors (SSRIs)
  • Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)

If anxiety disorders, particularly the Generalized Anxiety Disorder (GAD) are not treated, the prognosis is poor. Patients might develop complications like secondary depression, which may require medical and psychological therapy.

Though it’s treatable, anxiety disorder is among the most common and disabling mental disorders. Effective management requires early detection and treatment.


The development of an anxiety disorder can be prevented. The exact cause of anxiety disorders is still unknown, making it hard to prevent their development. However, there are steps to reduce anxiety and alleviate future episodes.

Another substance to avoid is coffee. Caffeine can cause increased anxiety.
