Patients with thyroid disorders may have had the experience of unintentionally finding a “nodule” in their neck, and then rushing to the hospital for a checkup. At this time, you must be confused, what is a “nodule”? Why do nodules grow? Is it serious or not? At this point you must have “100,000 questions” inside you. In fact, thyroid nodules, commonly known as “small lumps” in your thyroid gland, is a very common disease, especially among middle-aged women. Many causes can cause this disease, it is not yet completely clear how it is caused, but if you have had the following conditions, then the chances of developing thyroid nodules will increase, please pay attention! 1, suffering from a history of thyroid inflammation, such as acute septic thyroiditis, subacute thyroiditis, chronic lymphocytic thyroiditis, in the recovery phase of inflammation, thyroid tissue due to hyperplasia is prone to nodules. 2, too much iodine intake in food or drugs, such as like to eat nori, kelp, long-term use of iodine-rich drugs such as ethylamine-iodofuranone tablets, huasu tablets, etc.; of course, the intake of iodine in the diet is too little, the body is iodine-deficient over, also very easy to appear thyroid follicular epithelial cell hyperplasia, the formation of nodules. 3. After exposure to radioactive substances, thyroid nodules are likely to grow, and are mostly malignant. Previous exposure to radiation is an important causative factor for thyroid cancer, especially if you have been exposed to radiation in your neck during childhood or have a history of head and neck light exposure, the incidence of thyroid cancer in these people will be significantly higher after several years. Medication is not recommended for thyroid nodule patients, as it can only improve the symptoms, but not cure the disease. (Actually, I could list some drugs, but for the sake of my professionalism, please forgive me for not being able to list them, otherwise not only will they not cause disease, but they may harm people.) The treatment of thyroid nodules also depends on the patient’s age of onset, the cause of onset and the length of the condition. Patients must cooperate with their doctors to find the right treatment for them.
