Pneumothorax occurs when air gets trapped between a lung and the chest wall. This causes pressure on the lung, which can force it to give way, partially or completely, resulting in a collapsed lung. Since the lung cannot expand fully, breathing is difficult. In mild cases, some people do not notice any changes and the issue can resolve itself over time. More serious cases require surgery.


1. Causes

This breathing condition usually occurs because of an injury. However, lung disease may be the underlying cause of pneumothorax in some cases. Spontaneous pneumothorax develops on its own when no disease or injury is present. While a small spontaneous pneumothorax may be treated without medical attention, one caused by injury or lung disease requires treatment.
