The thyroid is a butterfly-shaped endocrine gland located below the Adam's apple in the lower part of the neck that wraps around the windpipe (trachea). Common thyroid problems include:
- Hyperthyroidism (also called overactive thyroid), a condition in which the body produces too much thyroid hormone and increases the body’s metabolism
- Hypothyroidism (underactive thyroid) occurs when a person produces insufficient amounts of thyroid hormone
- Hashimoto’s disease, of the most common cause of hypothyroidism
- Thyroid nodules and thyroid cancer
Tests done to check the thyroid for problems include:
- Blood tests
- Thyroid-stimulating hormone (TSH)
- Thyroxine (T4)
- Triiodothyronine (T3)
- Thyroid antibody tests
- Other blood tests to help determine the cause of hyperthyroidism (such as Graves' disease, toxic nodular goiter, or thyroiditis)
- Other tests
- Thyroid scan
- Ultrasound
- Radioactive iodine uptake test
- Fine needle aspiration biopsy for thyroid nodules
