Introduction
Anxiety is a normal emotional response to stress or danger. It is characterized by feelings of tension, worry, and physical changes like increased heart rate and sweating. While occasional anxiety is a normal part of life, chronic or intense anxiety that interferes with daily functioning may indicate an anxiety disorder.

Causes of Anxiety
Anxiety can result from a combination of biological, psychological, and environmental factors:
1. Genetic Factors
- Family history of anxiety or other mental health disorders increases risk.
2. Brain Chemistry
- Imbalance in neurotransmitters like serotonin, dopamine, and GABA may contribute to anxiety.
3. Stress and Trauma
- Chronic stress, childhood abuse, traumatic events, or loss of a loved one can trigger anxiety.
4. Personality Traits
- People with low self-esteem, perfectionism, or overthinking tendencies are more prone to anxiety.
5. Medical Conditions
- Conditions such as hyperthyroidism, heart disease, or respiratory disorders can mimic or worsen anxiety.
6. Substance Use
- Excessive caffeine, alcohol, or drug use can increase anxiety symptoms.
Conclusion
Anxiety is a natural response to stress but becomes a disorder when it interferes with daily life. Understanding its symptoms, types, and causes is essential for early recognition and treatment. With proper therapy, medication, and lifestyle changes, anxiety disorders are manageable and treatable.
