Which demographic is typically predisposed to a spontaneous pneumothorax?

The demographic predisposed to a spontaneous pneumothorax typically includes tall, thin, young adults. This group is often observed to have a higher incidence of spontaneous pneumothorax due to a combination of physiological factors. In many cases, the underlying cause is related to the anatomical considerations of lung apices that are more susceptible to the formation of blebs or bullae, which can rupture and lead to pneumothorax.

The taller build may contribute to a greater amount of lung tissue and the stress placed on the pleura due to rapid growth during adolescence and early adulthood. Additionally, the condition is more frequent in males within this age group, as they may engage in activities that increase the risk, such as vigorous exercise or certain sports.

This predisposition is well-documented in medical literature, which highlights how the combination of age, body type, and gender contributes significantly to the likelihood of experiencing a spontaneous pneumothorax.
