What are some common causes of respiratory distress?

Respiratory distress can stem from a variety of medical conditions, particularly those that directly affect the airways, lung function, and overall respiratory system. Asthma, chronic obstructive pulmonary disease (COPD), and heart failure are all well-known conditions that can lead to significant breathing difficulties.

Asthma involves inflammation and narrowing of the airways, making it hard to breathe, especially during an asthma attack. COPD is a progressive lung disease that causes obstructed airflow, typically due to long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. Heart failure can lead to fluid buildup in the lungs, further complicating the ability to breathe as the heart struggles to pump effectively, which can result in pulmonary edema.

Understanding these conditions is crucial for recognizing respiratory distress effectively, as they illustrate how various underlying health issues can compromise respiratory function. Additionally, while other options mention conditions that can impact health, they do not directly correspond to the primary causes of respiratory distress as specifically and prominently as the conditions listed in the correct choice.
