After drinking soy milk, feeling uncomfortable in the throat, the following clinical conditions may exist: 1. The patient’s body is allergic to the components of soy milk, resulting in throat discomfort. Soy milk is rich in protein and soy products. Some patients who are allergic to soy products may experience localized congestion or edema in the throat after drinking soy milk; 2. Patients may drink soy milk that is too hot or too cold, which stimulates the throat and leads to the symptoms of pharyngitis. For the above, it is recommended that the patient go to an ENT clinic to have the doctor examine the oropharynx and also use an electronic laryngoscope to examine the underside of the throat to see if there are any problems. In the case of edema due to local allergy, symptomatic treatment is needed by applying nebulization and, if necessary, hormones. If it only shows chronic pharyngitis, the patient is advised to drink more warm water. If the symptoms are severe, you can take tablets as well as proprietary Chinese medicine preparations for throat treatment for symptomatic treatment.
