Thyrotoxicosis is a disease that manifests itself as a result of excessive secretion of thyroid hormones in the body, which leads to increased excitability and hypermetabolism in the nervous, digestive, and circulatory systems. Diffuse goiter is the most common cause of thyrotoxicosis and occurs in adult women between the ages of 30 and 50, especially those with a history of thyroid disease, autoimmune disease, smoking, and alcohol consumption. thyrotoxicosis is usually caused by toxic nodular goiter in older patients over the age of 60, and is most common in iodine-deficient areas. The clinical manifestations of thyrotoxicosis include anxiety, fatigue, weight loss, heat intolerance, palpitations, and tremors in the hands. If left untreated or inadequately treated, thyrotoxicosis can easily lead to thyroid crisis, where patients may exhibit serious problems such as fever, altered mental status, heart failure, abnormal liver function, and tachycardia. Patients with thyrotoxicosis are prone to severe hypokalemia and acute muscle paralysis after strenuous physical activity and infection. Therefore, patients with thyrotoxicosis are recommended to take timely treatment to avoid aggravation of the disease. The specific treatment plan needs to be based on the patient’s condition to choose whether to use modern medical treatment or Chinese herbal medicine for evidence-based treatment.
