The common causes of frequent inflammation of the throat are: the persistence of inflammation in the neighboring areas, low immunity, and stimulation by adverse factors. 1. The persistence of inflammation in the neighboring parts: Since the throat is the same as the nasopharynx, if you originally suffer from rhinitis and sinusitis, due to the increased secretion of the nasal cavity, the nasal mucus flows backward to the throat, and the mucous membrane of the throat is stimulated by the nasal mucus for a long time, and it is repeatedly inflamed. 2. Low immunity: some people are weak, low immunity, when the environment temperature is lowered, dusty. Or increased pressure, overwork and other factors appear, easy to trigger the inflammation of the throat. 3. Adverse factors stimulation: often eat spicy stimulating food, stay up late, excessive use of voice, smoking and drinking, etc., is also the cause of frequent inflammation of the throat. There are other reasons for this condition, and if you can’t recover in a short period of time, you should go to the hospital in time to find out the cause of the problem and give symptomatic treatment.
