The thyroid gland is situated at the front of the throat, below the larynx (Adam’s apple), and comprises two lobes that lie on either side of the windpipe. The thyroid gland secretes hormones to regulate many metabolic processes, including growth and energy expenditure. If the thyroid gland is overactive or sluggish, the metabolism will be affected, leading to a variety of symptoms that are easily misdiagnosed. Around one in 20 people will experience some form of thyroid dysfunction in their lifetime. Women are more susceptible than men.
