Tiny foods that enter the trachea are not self-healing and require medical attention to remove the foreign body through bronchoscopy. After some tiny food, such as a grain of rice, mistakenly enters the airway, the human body has an instinctive coughing reflex to expel the small foreign body by choking and coughing. If the tiny food that enters the airway is not discharged by choking, the patient always feels uncomfortable in the airway, and it is easy to secondary bronchial and even lung infections over time, resulting in recurrent coughing, coughing up sputum, fever, etc., which can not be cured on its own. In this case, you must consult the doctor as soon as possible, and take the initiative to provide this special medical history to the doctor to facilitate the doctor’s judgment. In the case of tiny food stuck in the trachea, the doctor will apply bronchoscopy to remove the foreign body, and if there has been a secondary infection, anti-infection treatment can be given. In the process of eating and drinking, we should develop good habits, do not laugh and joke while eating, chew and swallow slowly to avoid some accidents caused by some small foods mistakenly entering the trachea.
