Hyperthyroidism  (甲状腺功能亢进)

甲状腺功能亢进症是一种内分泌疾病，其特征是甲状腺分泌和释放过多的甲状腺激素，导致甲状腺毒症和一系列全身性影响。常见症状包括神经质、易怒、体重减轻、怕热、心悸、震颤、疲劳、肌肉无力、失眠和月经周期改变。严重情况下，甲状腺功能亢进症可能发展为危及生命的甲状腺危象。最常见的病因是格雷夫斯病（一种自身免疫性疾病），其他病因包括毒性多结节性甲状腺肿和甲状腺炎。如果不及时治疗，甲状腺功能亢进症可导致严重的并发症，例如心房颤动、心力衰竭、骨质疏松症和不孕症。治疗方案包括抗甲状腺药物、放射性碘治疗和手术，目的是使激素水平正常化并缓解症状。

Hyperthyroidism is an endocrine disorder characterized by the overproduction and release of thyroid hormones by the thyroid gland, leading to thyrotoxicosis and a wide range of systemic effects. Common symptoms include nervousness, irritability, weight loss, heat intolerance, palpitations, tremors, fatigue, muscle weakness, insomnia, and changes in menstrual cycles. In severe cases, it can progress to thyroid storm, a life-threatening condition. The most frequent cause is Graves' disease, an autoimmune disorder, though other causes include toxic multinodular goiter and thyroiditis. Left untreated, hyperthyroidism can lead to serious complications such as atrial fibrillation, heart failure, osteoporosis, and infertility. Treatment options include antithyroid medications, radioactive iodine therapy, and surgery, with the goal of normalizing hormone levels and alleviating symptoms.
