Thyroid disorders generally have no specific symptoms in the early stages, and are relatively serious when symptoms are felt. The thyroid gland is an endocrine organ of the human body. Clinically, hypothyroidism, hyperthyroidism, thyroid nodules, thyroid cancer, thyroid tumors and other diseases are more common, but these diseases do not have obvious symptoms in the early stage, and the corresponding symptoms may appear in the later stage. Generally, thyroid nodules, thyroid tumors and thyroid cancer can be detected by ultrasound. In the early stage of thyroid cancer, there may be enlargement of the neck. In the later stage, the enlargement of the swelling may compress the trachea or nerves, causing difficulty in breathing, swallowing, and sometimes a certain degree of pain and discomfort. Hyperthyroidism may result in fear of heat, excessive sweating, panic attacks, agitation, increased food intake, loss of weight, and irregular menstruation. Hypothyroidism may cause fear of cold, body swelling, weight gain, rough skin, decreased food intake, and menstrual cycle disorders. It is important to go to the hospital promptly for examination and treatment after any uncomfortable symptoms appear.
