Food debris in the airways of adults does not go away on its own. If the foreign body is small, there is a possibility of expulsion. If the foreign body is large, it may block the trachea and cause serious consequences. 1. Smaller foreign bodies: When smaller food debris enters the trachea, the human organism’s self-protection consciousness will be activated, and there will be violent coughing and other bodily reactions, during which the smaller foreign bodies may be expelled from the trachea. 2. Larger foreign objects: If larger food debris enters the trachea, it is very likely to lead to trachea obstruction, making people feel breathless, and the situation is very dangerous, requiring emergency Heimlich maneuver. Adults with food debris in the trachea should seek medical attention as soon as possible, and remove the foreign body through bronchoscopic intervention with the help of a doctor to avoid blockage of food debris in the trachea or bacterial infection, which can lead to more serious consequences.
