Thyromegaly is an enlarged thyroid, the gland at the base of the neck that produces hormones that help the body balance metabolism. Medicalpoint notes that it is more commonly known as goiter.

When the thyroid becomes enlarged, it can become visible at the base of the neck, cause a tight sensation in the throat, or cause difficulty breathing or swallowing. Thyromegaly may not need to be treated unless it is causing discomfort or problems in the throat, but it should be checked by a doctor to rule out a severe underlying condition.

The most common causes of thyromegaly are iodine deficiency, the oversecretion of thyroid hormones (hyperthyroidism or Graves' disease) and the underproduction of thyroid hormones (hypothyroidism or Hashimoto's disease).
