It is possible for patients to develop pharyngitis without smoking, because there are many causes of pharyngitis, and smoking is only one of the common factors. Some patients suffer from acute bacterial or viral infections and inflammation, while others may suffer from improper diet, such as eating spicy and irritating foods, or eating foods to which they are allergic. Some patients may also suffer from chronic alcohol consumption or excessive use of the voice, and there are individual differences in the causes. After the onset of the disease, it is recommended to visit the ENT department for routine blood tests and laryngoscopy, which can help determine the condition and make a clear diagnosis. In terms of treatment, if the inflammatory reaction is mild, you can choose dietary regimen. If the inflammatory reaction is severe, it is necessary to cooperate with medication, which is more commonly taken orally, and nebulization can also be done.
