Coughing as a protective reflex

Coughing is a natural defense mechanism that helps clear the respiratory tract when something foreign, like a piece of food or a boba pearl, enters it. Dr. Sermed Mezher explained this on Instagram, using the example of a boba pearl to highlight how such objects trigger a strong coughing response.

Choking and airway irritation

Choking happens when food, liquid, or a foreign object enters the respiratory tract instead of the esophagus. This can cause irritation, watery eyes, and sudden coughing, as the body tries to remove the obstruction through this reflex action.

Intense coughing in healthy individuals

Dr. Mezher noted that a young, healthy person without neurological issues or vocal cord problems would likely experience a severe coughing fit if something like a boba pearl entered their airway. This reaction is consistent with the body's protective mechanisms.

Silent aspiration in young adults

While rare, silent aspiration—where a foreign object enters the respiratory tract without triggering a cough—is possible even in young adults without known health conditions. This risk is higher in specific situations, such as swallowing disorders, previous strokes, or neurological conditions.
