At the base of the neck, just over the collarbone is your thyroid. The thyroid is a gland that is shaped like a butterfly. This gland helps to determine how quickly a person burns off calories, how fast your heart beats, regulates your hormones, and more. If there is something off with the thyroid, a patient can have some pretty major symptoms that will need to be addressed. There can even be some life-threatening implications if hyperthyroidism is left untreated.
Information. Hyperthyroidism means that the thyroid is functioning too much. It produces too much of the thyroxin hormone. The thyroxin hormone can cause the body’s metabolism to speed up, which will cause some notable symptoms. Symptoms can vary, and will vary from person to person. Symptoms may come on all of a sudden, or they may be gradual in nature.
