Panic alone does not cause symptoms such as trembling of the hands and legs and sweating. If these symptoms occur together, it may be caused by hyperthyroidism. Hyperthyroidism refers to a disease in which the synthesis or release of thyroid hormones is excessive, leading to an increase in the level of thyroid hormones in the blood, which causes the body’s metabolic activity to increase, and the excitability of the nervous, circulatory, digestive and other systems to increase; common clinical symptoms include nervousness, anxiety, irritability, panic, trembling of the hands, excessive sweating, weight loss, and so on. For treatment, medication and surgery can be used. 1. Commonly used drugs include antithyroid drugs, such as methimazole, propylthiouracil, etc., which can reduce the synthesis of thyroid hormone; β-blockers, such as propranolol, metoprolol, etc., which can control the panic caused by hyperthyroidism; iodine, which can inhibit the synthesis and release of thyroid hormone, but it can only be applied temporarily for the preparation of preoperative, hyperthyroidism crisis and so on. 2. Surgery is suitable for patients with moderate or severe hyperthyroidism that is ineffective in drug treatment; goiter with compression symptoms; retrosternal goiter with hyperthyroidism; nodular thyroid hormone with hyperthyroidism; and patients suspected of malignant changes. Therefore, if the patient has symptoms such as panic, trembling hands, excessive sweating, etc., it is necessary to go to the hospital in time for examination, to clarify whether there is hyperthyroidism, and to choose the appropriate treatment plan according to the condition.
