What is the thyroid gland?
The thyroid gland is located at the base of the neck, and is comprised of two lobes (on each side of the windpipe), joined together by an isthmus.
The thyroid gland produces thyroxine (a thyroid hormone), which is important in regulating the metabolic rate of tissues and cells.
An overactive thyroid gland (hyperthyroidism) produces too much thyroxine and causes symptoms of tremor, palpitations, nervousness, poor sleep, weight loss, and heat intolerance.
An under active gland (hypothyroidism) causes the opposite type of symptoms due to a slowing of the metabolic rate. This may result in fatigue, weakness, weight gain, depression, cold intolerance, and dry rough skin.
