The difficulty in swallowing saliva may be due to thyroid problems, such as enlargement of the thyroid gland, which can easily compress the patient’s airway or even esophagus, resulting in difficulty in swallowing, but there is also a certain possibility that the difficulty in swallowing is caused by the patient’s tonsil hypertrophy or pharyngeal mucosa or epiglottis edema. It is advisable to go to the hospital for a detailed examination, either to the ENT department or to the general surgery department to clarify the cause, and it is best to check the laryngoscope and neck ultrasound to clearly identify the cause and avoid delaying the patient’s condition. It is recommended to take a light diet, and patients need to exercise properly to enhance their resistance.
