The thyroid gland does not cause chest pain. The thyroid gland is an important endocrine organ in the human body, and its role is to secrete thyroid hormones. Hypothyroidism is caused when too little thyroid hormone is secreted, and hyperthyroidism is caused when too much thyroid hormone is secreted. Both hyperthyroidism and hypothyroidism belong to metabolic diseases, both affect the body’s metabolic processes and may cause chest pain, which can be seen in the following cases: a. Hyperthyroidism, hyperthyroidism is caused by an excess of thyroid hormones, thyroid hormones can increase the metabolic rate, increase oxygen consumption, and also increase myocardial oxygen consumption, so it may cause hyperthyroidism heart disease. In middle-aged and elderly patients, especially in patients with ischemic heart disease, it can also cause anterior heart pain, chest pain and other symptoms of myocardial ischemia. Second, hypothyroidism, hypothyroidism is caused by too little secretion of thyroid hormone, hypothyroidism can cause slow heart rate, can also cause pericardial effusion, etc., individual patients may have chest pain. Therefore, the thyroid gland itself will not cause chest pain, but the abnormal function of the thyroid gland, that is, hyperthyroidism or hypothyroidism may cause chest pain.
