What it means

The thyroid gland is a butterfly-shaped gland located in the front of your neck, just below the Adam's apple. It produces hormones — mainly thyroxine (T4) and triiodothyronine (T3) — that regulate your metabolism, meaning how fast your body burns energy. Thyroid hormones also affect heart rate, body temperature, growth, and mood. The pituitary gland in your brain controls the thyroid by releasing thyroid-stimulating hormone (TSH). An overactive thyroid (hyperthyroidism) causes weight loss, rapid heartbeat, and anxiety. An underactive thyroid (hypothyroidism) causes fatigue, weight gain, and cold intolerance. Thyroid nodules, goiters (enlarged thyroid), and thyroid cancer are all conditions that affect this gland.
