The thyroid gland plays a major role in regulating metabolism, energy levels, body temperature, heart rate, and mood. When it does not function properly, even small imbalances in hormone production can affect nearly every system in the body. Because symptoms often develop slowly, many people do not realize there is an issue until the condition becomes more advanced.

One of the most common thyroid disorders is hyperthyroidism, where the gland produces too much hormone. This can speed up the body’s metabolism and lead to symptoms such as rapid heartbeat, anxiety, weight loss, excessive sweating, heat intolerance, and irritability.

Another common condition is hypothyroidism, which occurs when the thyroid does not produce enough hormones. This slows down body functions and may cause fatigue, weight gain, cold sensitivity, dry skin, constipation, memory issues, and depression
