What are the causes of female hypothyroidism?

Hypothyroidism is hypothyroidism. The causes of female hypothyroidism mainly include autoimmune diseases, thyroid surgery or radioactive iodine treatment, drug factors, pituitary or hypothalamic diseases, iodine deficiency, pregnancy-related factors, etc. 1. Autoimmune diseases Hashimoto thyroiditis is one of the common causes of hypothyroidism. When the body's immune system is abnormal, autoantibodies against the thyroid gland are produced, destroying thyroid tissue and resulting in decreased synthesis and secretion of thyroid hormones. This is more common in women and may be related to factors such as female hormone levels and genetic susceptibility. 2. Thyroid surgery or radioactive iodine treatment If a woman has undergone total or partial thyroidectomy for thyroid nodules, thyroid cancer, etc., or has received radioactive iodine treatment, the thyroid tissue will be significantly reduced, resulting in hypothyroidism. The direct damage to the thyroid gland by surgery and the destruction of thyroid cells by radioactive iodine will affect its function. 3. Drug factors Some drugs such as lithium salt and amiodarone may interfere with the synthesis or release of thyroid hormones, and long-term use may lead to hypothyroidism. Women need to pay close attention to changes in thyroid function when using these drugs. 4, pituitary or hypothalamic disease pituitary or hypothalamic secretion of thyrotropin releasing hormone, thyrotropin decreased, can not normally stimulate thyroid secretion of thyroid hormone, can also cause secondary hypothyroidism. This situation is relatively rare, but if there are pituitary tumors, hypothalamic lesions, etc., you need to consider. 5. Iodine deficiency In areas with severe iodine deficiency, if women consume insufficient iodine for a long time, it will lead to a lack of thyroid hormone synthesis raw materials, which in turn will cause hypothyroidism. However, with the popularity of iodized salt, this situation has become relatively rare. 6. Pregnancy-related factors Women during pregnancy, the demand for thyroid hormones increases, and if the thyroid gland does not increase secretion accordingly, hypothyroidism during pregnancy may occur. In addition, postpartum thyroiditis may also lead to transient hypothyroidism or permanent hypothyroidism. In short, the causes of female hypothyroidism are more complex, and the treatment methods for hypothyroidism caused by different reasons are also different. Therefore, when hypothyroidism is suspected, it should be promptly sought medical attention, relevant examinations should be carried out to clarify the cause, and standardized treatment should be carried out under the guidance of doctors.
