Hyperthyroidism or thyrotoxicosis results from excess quantities of thyroid hormone
in the body. This excess of hormones may be caused by tumors of the thyroid or rarely
of the pituitary or ovaries, inflammation of the thyroid, or ingestion of excessive
amounts of thyroid hormone or iodine. Those with increased thyroid hormone levels
experience heat intolerance, increased energy, difficulty sleeping, diarrhea and
anxiety.
