Enlargement of the laryngeal nodes can be seen in normal thin people with dry mouth and may be caused by inflammation of the larynx or thyroid disease. Inflammation of the larynx can lead to inflammation and enlargement of the lymph nodes around the larynx, accompanied by sore throat and dry mouth. The swelling of the laryngeal nodes and the surrounding lymph nodes will subside when the infection is controlled. Diseases of the thyroid gland, such as diffuse toxic goiter, simple goiter, multiple thyroid nodules, and thyroid cancer, may cause enlargement of the laryngeal nodes. If you often feel dry mouth, eat too much and lose weight recently, you need to go to the hospital for a thyroid ultrasound and thyroid hormone level test to make a clear diagnosis for further treatment.
