Guide To The Causes, Risk Factors, And Complications Of Thyroid Nodules

Thyroid nodules are lumps or growths in an individual's thyroid gland above their breastbone and at the base of their neck. The majority of thyroid nodules do not produce symptoms or cause any issues. However, some nodules can make it hard for a patient to swallow correctly, breathe well, and produce a healthy amount of thyroid hormone called thyroxine. Thyroid nodules that produce excess hormones can result in symptoms such as unexplained weight loss, tremor, rapid heartbeat, increased sweating, and nervousness. Thyroid nodules can be identified through the use of a physical examination, thyroid function tests, thyroid scans, ultrasonography, and fine-needle aspiration. Thyroid nodule treatment is dependent upon the type of nodules and the symptoms they produce, though common methods include thyroid hormone suppression therapy, surgery, radioactive iodine, anti-thyroid medications, and alcohol ablation.
