Your thyroid is a tiny butterfly-shaped gland found at the base of your neck, a gland that weighs less than an ounce but plays a critical role in your body. A common disorder related to the thyroid is hyperthyroidism, which is an overactive thyroid in which your thyroid begins to produce too much thyroxine. Once you understand what the thyroid does in your body, it is easier to understand the seemingly random symptoms of hyperthyroidism.
