Most patients with hyperthyroidism have goiter of varying degrees, while a few patients have no goiter, especially elderly patients. Thyroid gland is diffuse, symmetrical swelling, soft in texture, and moves up and down when swallowing. However, in addition to hyperthyroidism, there are other diseases that can also cause goiter, such as iodine deficiency, bad habit of smoking and drinking, insulin resistance, hypothyroidism, thyroid inflammation, or increased iodide content in food and water, which can cause thyroid substances (such as cabbage, cabbage, cauliflower, cabbage, etc.) and certain drugs (thiourea, sulfur? Acid salt, perchlorate, lithium salt, etc.) can also cause goiter.
