With the development of society and changes in people’s lifestyles in recent years, thyroid disorders are on the rise. Many people have questions about whether a nodule on the thyroid gland means that you have hyperthyroidism. In fact, thyroid nodules are a very common disease, and are two different diseases from hyperthyroidism. Let’s learn more about what happens when there are nodules on the thyroid gland. What is a thyroid nodule? A thyroid nodule is the collective name for a lump in the thyroid gland, which is a common thyroid condition, especially in middle-aged women. Thyroid nodules are complicated by a variety of thyroid disorders, such as simple goiter, thyroiditis, and thyroid tumors, all of which can manifest clinically as nodules. Thyroid nodules can be solitary or multiple. Multiple nodules have a higher incidence than solitary nodules, but solitary nodules have a higher incidence of thyroid cancer. There is a difference between benign and malignant nodules, with benign nodules accounting for the majority and less than 1% of malignant nodules. Early recognition of the nature of thyroid nodules, especially the distinction between benign and malignant lesions, is important for the choice of treatment options and prognosis. Difference between thyroid nodules and hyperthyroidism Hyperthyroidism is a disorder of the endocrine system caused by an overproduction of thyroid hormones due to hyperthyroidism. A thyroid nodule is a lump in the thyroid gland that moves up and down with the thyroid gland with swallowing movements. It is a common clinical condition that can be caused by a variety of factors and is mainly an endocrine system disorder caused by degenerative changes in the thyroid gland. It can be differentiated by ultrasound and thyroid function tests. It is common for adults to have nodules on the thyroid gland. Patients with nodules on the thyroid gland do not necessarily affect the function of the thyroid gland, which means that these patients may have normal thyroid function. Only a very small number of patients with nodules on the thyroid gland are accompanied by hyperthyroidism. The different symptoms of thyroid nodules and hyperthyroidism The symptoms of thyroid nodules are: the disease progresses slowly and most patients are asymptomatic. The nodules are soft or slightly hard, smooth and painless to the touch. Touching the surface of the thyroid gland only gives an irregular or lobulated sensation. Larger nodular goiters may cause symptoms of pressure, difficulty breathing, difficulty swallowing and hoarseness. The symptoms of hyperthyroidism are: patients may suffer from insomnia and nervousness, restlessness, and easy to get angry, etc.; they may eat a lot and lose weight, and some of them may have diarrhea due to rapid metabolism; many patients with hyperthyroidism may have panic attacks and palpitations in the early stage, and their heart beats faster than normal people. As the disease progresses, various cardiovascular diseases such as heart disease may appear.
