If you have betel nut residue stuck in your throat, you can eat or drink to make it slide off; if the location is shallow and the betel nut residue is large, you can use tweezers to remove it.
Betel nut residue is a granular hard object, the throat is more narrow and complex cavity, so it is easier to get stuck in larger and harder chunks of food. Generally, it can slide off naturally with eating, swallowing and breathing; if it still does not slide off and the location is shallow, it is recommended to consult a doctor in time to remove it with tweezers.
If the stuck position is deeper and more hidden, or there is discomfort, such as breathing difficulties, foreign body sensation, hoarseness, etc., you need to go to the hospital in a timely manner, in the laryngoscope, tracheoscopy, forceps and other professional equipment operation for foreign body removal.
