The thyroid is a small, butterfly-shaped gland located at the base of the neck, playing a crucial role in regulating your body’s metabolism. It produces hormones—primarily thyroxine (T4) and triiodothyronine (T3)—that influence almost every cell, organ, and system in the body.
The hormones produced by the thyroid control how your body uses energy, affecting processes like heart rate, body temperature, and weight management. When the thyroid is functioning properly, it keeps these systems in balance, ensuring that your body operates efficiently.
Thyroid disorders can occur when the gland produces too much or too little hormone. Hyperthyroidism, or an overactive thyroid, can lead to symptoms like weight loss, rapid heartbeat, and anxiety. Hypothyroidism, or an underactive thyroid, often causes fatigue, weight gain, and depression. Both conditions are treatable with medication and lifestyle adjustments.
