The thyroid is a butterfly-shaped endocrine gland that is normally located in the lower front of the neck. The thyroid’s job is to make thyroid hormones, which are secreted into the blood and then carried to every tissue in the body.

The thyroid hormone helps the body use energy, stay warm, keep the brain, heart, muscles, and other organs working as they should, and regulate the body's metabolism.

Thyroid disorders can cause a variety of symptoms, including weight gain or loss, fatigue, anxiety, and depression.

There are a number of disorders that can affect the thyroid gland, such as hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). Thyroid cancer is also a possibility, though it is relatively rare.

Most thyroid disorders are treatable with medication.
