The thyroid is a butterfly-shaped gland at the base of the neck that is responsible for the production of vital hormones that regulate several bodily functions. Thyroid hormones are essential for one’s metabolism as well as for overall growth and development. An overactive thyroid causes what is medically known as hyperthyroidism, while an underactive thyroid leads to hypothyroidism. Both of these conditions can have a serious impact on a person’s routine health and well-being, thus making them a cause of much concern. To detect dysfunction of the thyroid gland, one must be aware of the various symptoms that it can produce. Here are ten signs that may be indicative of thyroid problems and that, if observed, need to be evaluated further by your doctor.
