What are 2 conditions in which hyperventilation may occur?

Hyperventilation can occur in a variety of conditions, including:

1. Anxiety disorders: Hyperventilation is a common symptom of anxiety disorders, such as panic disorder and generalized anxiety disorder. During an anxiety attack, people may experience a sudden onset of intense fear or panic, which can lead to rapid breathing and hyperventilation.

2. Respiratory conditions: Hyperventilation can also occur in respiratory conditions that affect the lungs or airways, such as asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. In these conditions, the airways may become narrowed or obstructed, making it difficult to breathe, which can lead to rapid, shallow breathing and hyperventilation.
