If the goiter is not serious and the thyroid function is normal in the early stage, there are usually no obvious symptoms. As the goiter grows, there may be signs such as compression of the trachea, compression of the jugular veins, compression of the esophagus, compression of the recurrent laryngeal nerve, hyperthyroidism, and hypothyroidism. 1. Compression of the trachea: An enlarged thyroid gland may compress the trachea and may soften the body’s windpipe, which may lead to breathing difficulties. 2. Compression of the neck veins: An enlarged thyroid gland may also cause obstruction of blood flow to the body, which may compress the neck veins and lead to facial edema or blood stasis. 3. Compression of the esophagus: It may also gradually expand into the esophagus and compress its own esophagus, leading to difficulty in swallowing. 4. Compression of the recurrent laryngeal nerve: If the recurrent laryngeal nerve is compressed, hoarseness and spasmodic coughing may occur. 5. Symptoms of hyperthyroidism: If goiter is combined with hyperthyroidism, when the thyroid cells are destroyed, symptoms related to hyperthyroidism, such as excessive sweating, fear of heat, palpitations, etc., will appear. 6. Hypothyroidism Symptoms: If goiter is combined with hypothyroidism, hypothyroidism-related symptoms, such as fatigue, fear of cold, etc., will appear. If the phenomenon of goiter occurs, you need to consult the doctor as soon as possible for examination, and actively and correctly deal with the disease.
