Anxiety disorders are among the most common mental illnesses in the world. Although it is normal to be anxious at times, anxiety disorders involve excessive, persistent worry or fear that interferes with daily life. Anxious feelings and thoughts, if not treated, can lead to long-term physical and emotional health problems.

What Is an Anxiety Disorder?

An anxiety disorder is a mental illness that includes ongoing, intense feelings of fear, worry, or panic. These emotions are often accompanied by physical symptoms like restlessness, perspiration, or a quick pulse. Anxiety becomes difficult to control and causes distress in social, school, or work environments for many.

Fast Fact: More than 301 million individuals globally suffered from an anxiety disorder in 2019 — making it the most prevalent mental illness worldwide.

Prevalent Anxiety Disorder Symptoms

Individuals with anxiety disorders might experience:

• A feeling of dread, panic, or impending doom
• Difficulty concentrating or making decisions
• Irritability or restlessness
• Nausea or stomach discomfort
• Sweating, tremors, or shakiness
• Insomnia
• Avoidance of situations that induce anxiety

If the symptoms persist for six or more months, they may be symptoms of a treatable anxiety disorder.

Anxiety Disorder Types

Anxiety disorders come in several different types, with their respective symptoms and stimuli:

1. Generalized Anxiety Disorder (GAD)

Persistent, excessive worrying about things occurring in everyday life, without apparent reason.

2. Panic Disorder

Recurring panic attacks and constant fear of additional attacks.

3. Social Anxiety Disorder

Severe fear of social performance or criticism by others.

4. Agoraphobia

Fear of public places or situations that may result in panic or helplessness.

5. Separation Anxiety Disorder

Overwhelming fear of being away from loved ones, commonly experienced by children.

6. Specific Phobias

Irrational fear of specific objects or situations (e.g., fear of heights, spiders, flying).

7. Selective Mutism

Persistent failure to speak in specific contexts, with fluent speech elsewhere (mostly occurs in children).

Multiple anxiety disorders can be present at the same time.

What causes anxiety disorders?

A combination of biological, psychological, and environmental factors is responsible for anxiety disorders. Some of these factors are:

• Abusive life experiences (e.g., violence, abuse, loss)
• Family history of anxiety or mental illness
• Chronic illness
• Brain chemical imbalance
• Persistent stress or poor coping strategies

Additionally, women are more likely to be given an anxiety disorder diagnosis than men.

Risk Factors & Long-Term Consequences

If not treated, anxiety disorders can escalate to:

• Depression or drug abuse
• Suicidal thoughts and actions
• Chronic disease that is stress-related (heart disease)
• Poorer quality of life and tense relationships

Diagnosis and Treatment Options for Anxiety

1. Psychological Interventions

Cognitive-behavioral therapy (CBT) is the best type of talk therapy for anxiety. CBT teaches individuals how to recognize and change negative thinking patterns and behaviors.

Other therapies applied include:

• Exposure therapy
• Group therapy
• Mindfulness-based therapies
• Online websites or self-help applications

2. Medications

• SSRIs (Selective Serotonin Reuptake Inhibitors) are a commonly prescribed medication for anxiety. 
• Benzodiazepines offer short-term relief but are not recommended long-term because they lead to dependency problems.

Always consult a licensed mental health professional before using medication.

Self-Care Methods for Managing Anxiety

In addition to therapy or medication, self-care can reduce symptoms and overall mental well-being:

• Don't use alcohol and recreational drugs
• Exercise every day—short walks are good too
• Stick to regular sleep and meal schedules
• Practice relaxation skills (deep breathing, muscle relaxation)
• Try mindfulness or meditation daily—even 5 minutes matter.

Why So Few Get Treated (And Why That Must Change)

Despite having effective treatments, only approximately 1 in 4 people who experience anxiety are treated. The reasons for this are:

• Unawareness of mental health
• Social stigma
• Insufficiently funded health services
• Inadequate trained staff

Building awareness and reducing stigma are critical to improving access to care.

Final Thoughts: Don't Ignore Anxiety

Anxiety disorders are real, common, and treatable. If you or someone you care about is experiencing persistent anxiety, finding a healthcare professional is the initial and most important step in the healing process.
